RescueFundsLib performs token/ETH transfers with its own checks. + +### `Socket.sol` +- Constructor simply seeds `gasLimitBuffer`; shared setup happens in `SocketUtils`. +- `execute` validates deadline, call type (`WRITE`), plug registration, `msg.value`, payload ID, execution status, and the switchboard signature chain before invoking user code. +- `_verify` delegates to the switchboard and stores the digest, reverting on failure. +- `_execute` checks available gas against the requested limit (buffered by 5%), then delegates via `LibCall.tryCall`. +- `_handleSuccessfulExecution` emits status and forwards socket fees only when a collector is configured. +- `_handleFailedExecution` marks the payload as `Reverted` and refunds all forwarded funds to either the requester or `refundAddress`. +- `_validateExecutionStatus` guarantees idempotence by blocking second executions unless the prior attempt reverted. +- `sendPayload` and `_sendPayload` both require plugs to be registered before passing control to a switchboard, ensuring only valid relationships exist. +- `fallback` and `receive` either proxy to `_sendPayload` or revert, avoiding accidental ETH acceptance. + +### `SocketBatcher.sol` +- Constructor stores the socket reference and initializes ownership; no user-controlled inputs. +- `attestAndExecute` fetches the specified switchboard and calls `attest` before `socket__.execute`, maintaining the pre-attestation requirement. +- `rescueFunds` is owner-only and routes through `RescueFundsLib`. + +### `SocketConfig.sol` +- `registerSwitchboard` prevents duplicate registrations (`SwitchboardExists`) before assigning IDs. +- `disableSwitchboard`/`enableSwitchboard` change status flags under role control so invalid switchboards cannot be selected. +- `setNetworkFeeCollector` updates the collector address atomically via governance. +- `connect` enforces non-zero switchboard IDs and `REGISTERED` status before emitting configuration. +- `updatePlugConfig` requires prior connection; otherwise `PlugNotConnected` reverts. +- `disconnect` clears the switchboard mapping only when the plug was connected. +- `setGasLimitBuffer` and `setMaxCopyBytes` are governance-only, so downstream gas assumptions stay coherent. +- `getPlugConfig`/`getPlugSwitchboard` simply return stored metadata without mutating state. + +### `SocketUtils.sol` +- Constructor stores the chain slug, hashes the version, and initializes ownership, satisfying immutability requirements. +- `_createDigest` length-prefixes dynamic fields to avoid collision attacks, fulfilling the digest contract. +- `simulate` uses `onlyOffChain` so that on-chain callers cannot consume arbitrary gas or reveal state. +- `_verifyPlugSwitchboard` reverts when plugs are unregistered or tied to disabled switchboards. +- `_verifyPayloadId` ensures the verification metadata embedded in `payloadId` matches the currently authorized switchboard for the target chain. +- `increaseFeesForPayload` first checks that the caller is a registered plug; the downstream switchboard decides whether the fee update is meaningful (finding RV-1 highlights missing logic in the fast switchboard). +- `rescueFunds`, `pause`, and `unpause` each enforce their respective roles so operational requirements remain intact. + +### `switchboard/SwitchboardBase.sol` +- Constructor pins the socket and chain slug while initializing ownership, preventing later reconfiguration. +- `registerSwitchboard` can only be triggered by the owner and simply proxies to `socket__.registerSwitchboard`. +- `getTransmitter` either recovers a signer from `transmitterSignature_` or returns zero, ensuring downstream callers know whether authentication happened. +- `_recoverSigner` is internal and wraps `ECDSA.recover` with the expected prefix. +- `rescueFunds` is role-guarded. + +### `switchboard/FastSwitchboard.sol` +- Constructor simply feeds its parameters into `SwitchboardBase`. +- `attest` verifies watchers via `_recoverSigner` and `WATCHER_ROLE`. +- `allowPayload` ensures the source matches `plugAppGatewayIds` before honoring attestations. +- `setEvmxConfig` demands ownership to avoid misconfiguration. +- `processPayload` guards against unset EVMX config, auto-fills missing deadlines, and increments the payload counter safely. +- `increaseFeesForPayload` suffers from RV-1 (no requirement checks or state changes). +- `updatePlugConfig` decodes and stores the `appGatewayId` under socket control. +- `setRevertingPayload` and `setDefaultDeadline` are owner-only toggles. +- `getPlugConfig` returns the stored mapping value; no user input. + +### `switchboard/MessageSwitchboard.sol` +- Constructor defers to `SwitchboardBase`. +- `setSiblingConfig` requires ownership and writes all three sibling mappings atomically. +- `setRevertingPayload` flips the inherited mapping under owner control. +- `processPayload` enforces override version, sibling existence, min-fee rules, and sponsor approvals before emitting `MessageOutbound`. +- `_decodeOverrides` validates version bytes and supplies default deadlines when omitted. +- `_validateSibling` ensures socket, switchboard, and plug entries exist for the chosen destination chain. +- `_createDigestAndPayloadId` constructs payload IDs deterministically and reverts if the destination switchboard ID is missing. +- `approvePlug`/`approvePlugs` and `revokePlug`/`revokePlugs` manipulate sponsor approvals directly; no user-controlled arithmetic involved. +- `attest` enforces watcher signatures and prevents duplicate attestations. +- `markRefundEligible` requires watcher approval and ensures the payload has refundable fees before flagging eligibility. +- `refund` checks eligibility and idempotence before transferring ETH to the recorded `refundAddress`. +- `setMinMsgValueFees` and `setMinMsgValueFeesBatch` both recover fee-updater signatures (with nonce tracking) and revert on mismatched array lengths. +- `setMinMsgValueFeesOwner` and `setMinMsgValueFeesBatchOwner` give governance a direct override path subject to array length checks. +- `increaseFeesForPayload` delegates to `_increaseNativeFees`/`_increaseSponsoredFees` after decoding the fee type. +- `_increaseNativeFees` and `_increaseSponsoredFees` both confirm that the caller plug matches the payload creator. +- `allowPayload` decodes the source tuple and ensures it matches the registered sibling plug before trusting the attestation. +- `_createDigest` mirrors `_createDigestAndPayloadId`’s encoding strategy to maintain uniqueness guarantees. +- `updatePlugConfig` decodes `(chainSlug, siblingPlug)` and validates sibling sockets/switchboards before storing. +- `getPlugConfig` simply returns the encoded sibling plug for the requested chain. + +## References +- Requirement validation guidance: [https://kadenzipfel.github.io/smart-contract-vulnerabilities/vulnerabilities/requirement-violation.html](https://kadenzipfel.github.io/smart-contract-vulnerabilities/vulnerabilities/requirement-violation.html) + diff --git a/internal-audit/done/UNUSED_VARIABLES_AUDIT.md b/internal-audit/done/UNUSED_VARIABLES_AUDIT.md new file mode 100644 index 00000000..1601e08e --- /dev/null +++ b/internal-audit/done/UNUSED_VARIABLES_AUDIT.md @@ -0,0 +1,61 @@ +# Unused Variables Audit – `contracts/protocol` + +Unused state or local variables often signal incomplete logic, wasted gas, or hidden bugs per SWC-131 guidance [source](https://kadenzipfel.github.io/smart-contract-vulnerabilities/vulnerabilities/unused-variables.html).

🔴 Critical Security Issues + +### 1. Reentrancy Vulnerability +**Location:** `SocketConfig.connect(uint32,bytes)` (lines 164-169, 521-526, 733-738) +**Issue:** External call to `ISwitchboard.updatePlugConfig()` is made before emitting the `PlugConnected` event. This creates a reentrancy risk where state changes occur after external calls. +**Recommendation:** Follow checks-effects-interactions pattern: emit events before external calls, or use reentrancy guards. + +### 2. Unused Return Value +**Location:** `SocketBatcher.attestAndExecute()` (line 17-18) +**Issue:** The return value from `socket__.execute()` is ignored. If `execute()` returns important status information, this could lead to missed error handling. +**Recommendation:** Check and handle the return value appropriately, or explicitly mark it as intentionally ignored. + +### 3. Ether Locking +**Location:** `SocketConfig` contract (lines 720-731) +**Issue:** Contract has payable functions (via `ISocket` interface) but no withdrawal mechanism. Ether sent to this contract could be permanently locked. +**Recommendation:** Add a withdrawal function or ensure ether is properly forwarded/used in payable functions. + +### 4. Arbitrary Ether Transfer +**Location:** `Socket._handleSuccessfulExecution()` (lines 511-514) +**Issue:** Sends ETH to `networkFeeCollector.collectNetworkFee()` which may be an arbitrary address. +**Recommendation:** Verify that `networkFeeCollector` is a trusted, immutable address, or add proper validation. + +### 5. Block Timestamp Dependency +**Location:** `Socket.execute()` (lines 528-531) +**Issue:** Uses `block.timestamp` for deadline comparison (`executionParams_.deadline < block.timestamp`). +**Recommendation:** Be aware that miners can manipulate timestamps within a small range. Consider if this is acceptable for your use case. + +## 🟡 Medium Priority Issues + +### 6. Unimplemented Interface Functions +**Location:** +- `SocketUtils` (lines 358-363): Missing `execute()`, `executionStatus()`, `payloadIdToDigest()`, `sendPayload()` +- `SocketConfig` (lines 828-835): Missing `chainSlug()`, `execute()`, `executionStatus()`, `increaseFeesForPayload()`, `payloadIdToDigest()`, `sendPayload()` + +**Issue:** Contracts claim to implement `ISocket` interface but are missing required functions. +**Recommendation:** Either implement all interface functions or remove the interface inheritance if not needed. + +### 7. Dead Code +**Location:** Multiple functions identified as unused (lines 280-291, 643-649, 788-796) +**Functions:** +- `AccessControl._checkRole()` +- `SocketUtils._createDigest()` +- `SocketUtils._verifyPayloadId()` +- `convertToSolanaUint64()` +- `createPayloadId()` +- `decodePayloadId()` +- `fromBytes32Format()` +- `getOriginInfo()` +- `getVerificationInfo()` +- `toBytes32Format()` +- `Pausable._pause()` and `_unpause()` + +**Recommendation:** Remove unused code to reduce contract size and improve maintainability, or document why they're kept for future use. + +### 8. Unused State Variables +**Location:** +- `AccessControl._gap_access_control` in `NetworkFeeCollector` and `Socket` (lines 508-509, 717-718) + +**Issue:** Storage gap variable is declared but never used. +**Recommendation:** If this is for upgradeability, ensure it's properly sized. Otherwise, consider removing it. + +## 🟢 Low Priority / Informational + +### 9. Solidity Version Mismatch +**Issue:** Two different Solidity versions used: +- `^0.8.21` in protocol contracts +- `^0.8.4` in solady libraries + +**Note:** This is expected when using external libraries. However, be aware that: +- `^0.8.21` has known issue: `VerbatimInvalidDeduplication` +- `^0.8.4` has multiple known issues (listed in output) + +**Recommendation:** Consider upgrading to newer, more stable versions if possible, or ensure you're aware of the limitations. + +### 10. Naming Conventions +**Location:** +- `SocketBatcher.socket__` (line 126) +- `AccessControl._gap_access_control` (lines 325, 475, 684, 825) + +**Issue:** Variables don't follow mixedCase naming convention. +**Recommendation:** Follow Solidity style guide for consistency. + +### 11. Library Code Findings (Expected) +The following findings are in external library code (solady) and are expected: +- Assembly usage (lines 25-84, 171-254, etc.) +- Write-after-write in `SafeTransferLib.permit2()` (lines 19-23, 159-162, etc.) +- Too many digits in literals (lines 129-157, etc.) + +**Note:** These are informational and expected in optimized library code. + +## Summary Statistics + +- **Security Issues:** 5 critical findings +- **Code Quality:** 3 medium priority issues +- **Informational:** Multiple findings (mostly in libraries) +- **Total Contracts Analyzed:** 55 +- **Total Detectors Run:** 100 + +## Recommended Actions + +1. **Immediate:** Fix reentrancy issue in `SocketConfig.connect()` +2. **High Priority:** Review and fix ether locking in `SocketConfig` +3. **High Priority:** Verify return value handling in `SocketBatcher.attestAndExecute()` +4. **Medium Priority:** Implement missing interface functions or remove interface inheritance +5. **Medium Priority:** Clean up dead code +6. **Low Priority:** Address naming conventions for consistency + +--- + +*Note: Many findings related to library code (solady) are expected and don't require action unless you're maintaining those libraries.* + diff --git a/internal-audit/slither/output.txt b/internal-audit/slither/output.txt new file mode 100644 index 00000000..f6289474 --- /dev/null +++

protocol contracts with their context and surrounding code. - ---- - -## 1. MessageSwitchboard.sol - -### Audit 1: Overflow/Underflow Check in Fee Validation - -**Location:** `contracts/protocol/switchboard/MessageSwitchboard.sol:218` - -**Context:** - -```218:220:contracts/protocol/switchboard/MessageSwitchboard.sol - // @audit should check for overflow/underflow? - if (msg.value < minMsgValueFees[overrides.dstChainSlug] + overrides.value) - revert InsufficientMsgValue(); -``` - -**Function:** `processPayload()` - Native token flow validation - -**Issue:** The addition `minMsgValueFees[overrides.dstChainSlug] + overrides.value` could potentially overflow, though Solidity 0.8+ has built-in overflow protection. The audit question suggests verifying if explicit checks are needed. - ---- - -### Audit 2: Reentrancy Guard in Refund Function - -**Location:** `contracts/protocol/switchboard/MessageSwitchboard.sol:442` - -**Context:** - -```441:453:contracts/protocol/switchboard/MessageSwitchboard.sol - function refund(bytes32 payloadId_) external { - // @audit do we need nonReentrant here? - PayloadFees storage fees = payloadFees[payloadId_]; - if (!fees.isRefundEligible) revert RefundNotEligible(); - if (fees.isRefunded) revert AlreadyRefunded(); - - uint256 feesToRefund = fees.nativeFees; - fees.isRefunded = true; - fees.nativeFees = 0; - - SafeTransferLib.safeTransferETH(fees.refundAddress, feesToRefund); - emit Refunded(payloadId_, fees.refundAddress, feesToRefund); - } -``` - -**Function:** `refund()` - Refund claim function - -**Issue:** The function performs an external ETH transfer before updating state. While state is updated before the transfer, the question is whether a reentrancy guard is needed to prevent potential reentrancy attacks through the refund address. - ---- - -### Audit 3: Verification of Plug and PayloadId Before Fee Increase - -**Location:** `contracts/protocol/switchboard/MessageSwitchboard.sol:566` _(REMOVED)_ - -**Context:** - -```561:580:contracts/protocol/switchboard/MessageSwitchboard.sol - function increaseFeesForPayload( - bytes32 payloadId_, - address plug_, - bytes calldata feesData_ - ) external payable override onlySocket { - // Decode the fees type from feesData - uint8 feesType = abi.decode(feesData_, (uint8)); - - if (feesType == 1) { - // Native fees increase - _increaseNativeFees(payloadId_, plug_, feesData_); - } else if (feesType == 2) { - // Sponsored fees increase - _increaseSponsoredFees(payloadId_, plug_, feesData_); - } else { - revert InvalidFeesType(); - } - } -``` - -**Function:** `increaseFeesForPayload()` - Fee increase function - -**Status:** The audit tag has been removed from this function. The internal functions `_increaseNativeFees` and `_increaseSponsoredFees` check that the plug matches the one that created the payload, which may address the original concern. - ---- - -## 2. NetworkFeeCollector.sol - -### Audit 4: Access Control for collectNetworkFee - -**Location:** `contracts/protocol/NetworkFeeCollector.sol:73` - -**Context:** - -```67:76:contracts/protocol/NetworkFeeCollector.sol - function collectNetworkFee( - ExecutionParams calldata executionParams_, - TransmissionParams calldata transmissionParams_ - ) external payable onlyRole(SOCKET_ROLE) { - if (msg.value < networkFee) revert InsufficientFees(); - - // @audit can be called by anyone, with random params value - // add onlySocket? - emit NetworkFeeCollected(msg.value, executionParams_, transmissionParams_); - } -``` - -**Function:** `collectNetworkFee()` - Network fee collection - -**Issue:** The function has `onlyRole(SOCKET_ROLE)` modifier, but the audit comment suggests concern that anyone with SOCKET_ROLE could call this with random parameters. The comment suggests adding `onlySocket` modifier, but the function already has role-based access control. The concern might be about parameter validation or ensuring only the Socket contract itself can call this (not just any address with SOCKET_ROLE). - ---- - -## 3. Socket.sol - -### Audit 5: Input Validation in Constructor - -**Location:** `contracts/protocol/Socket.sol:36` - -**Context:** - -```32:39:contracts/protocol/Socket.sol - constructor( - uint32 chainSlug_, - address owner_ - ) SocketUtils(chainSlug_, owner_) { - // @audit do we need input validation in constructor? - // @note: should not be less than 100 - gasLimitBuffer = 105; - } -``` - -**Function:** `constructor()` - Socket contract initialization - -**Issue:** The constructor doesn't validate inputs like `chainSlug_` or `owner_`. The note suggests `chainSlug_` should not be less than 100, but there's no explicit validation. Also, `owner_` could be `address(0)` which might cause issues. - ---- - -### Audit 6: Reentrancy Guard in Execute Function - -**Location:** `contracts/protocol/Socket.sol:52` - -**Context:** - -```48:77:contracts/protocol/Socket.sol - function execute( - ExecutionParams memory executionParams_, - TransmissionParams calldata transmissionParams_ - ) external payable whenNotPaused returns (bool, bytes memory) { - // @audit do we need nonReentrant here? - // check if the deadline has passed - if (executionParams_.deadline < block.timestamp) revert DeadlinePassed(); - - // check if the call type is valid - if (executionParams_.callType != WRITE) revert InvalidCallType(); - - // check if the plug is connected - address switchboardAddress = _verifyPlugSwitchboard(executionParams_.target); - - // check if the message value is sufficient - if (msg.value < executionParams_.value + transmissionParams_.socketFees) - revert InsufficientMsgValue(); - - // verify the payload id - _verifyPayloadId(executionParams_.payloadId, switchboardAddress); - - // validate the execution status - _validateExecutionStatus(executionParams_.payloadId); - - // verify the digest - _verify(switchboardAddress, executionParams_, transmissionParams_.transmitterProof); - - // execute the payload - return _execute(executionParams_, transmissionParams_); - } -``` - -**Function:** `execute()` - Main payload execution function - -**Issue:** The function performs external calls through `_execute()` which calls untrusted contracts. The execution status is set before the external call, but the question is whether a reentrancy guard is needed to prevent reentrancy attacks. - ---- - -### Audit 7: Gas Limit Type Restriction - -**Location:** `contracts/protocol/Socket.sol:125` - -**Context:** - -```118:138:contracts/protocol/Socket.sol - function _execute( - ExecutionParams memory executionParams_, - TransmissionParams calldata transmissionParams_ - ) internal returns (bool success, bytes memory returnData) { - // check if the gas limit is sufficient - // bump by 5% to account for gas used by current contract execution - - // @audit should we restrict gaslimit to uint64 to prevent overflow/underflow? - if (gasleft() < (executionParams_.gasLimit * gasLimitBuffer) / 100) revert LowGasLimit(); - - // NOTE: external un-trusted call - bool exceededMaxCopy; - // @audit do we need to check if the target is a contract? - // potential risk is, what if a contract connects to socket and use self destruct? - // in this case, .call will return success = true but the call will go to an eoa - (success, exceededMaxCopy, returnData) = executionParams_.target.tryCall( - executionParams_.value, - executionParams_.gasLimit, - maxCopyBytes, - executionParams_.payload - ); -``` - -**Function:** `_execute()` - Internal execution function - -**Issue:** The `executionParams_.gasLimit` is a `uint256`, but the audit suggests restricting it to `uint64` to prevent overflow/underflow in the multiplication `executionParams_.gasLimit * gasLimitBuffer`. While Solidity 0.8+ has overflow protection, restricting the type could prevent edge cases. - ---- - -### Audit 8: Contract Existence Check Before Execution - -**Location:** `contracts/protocol/Socket.sol:130` - -**Context:** - -```118:138:contracts/protocol/Socket.sol - function _execute( - ExecutionParams memory executionParams_, - TransmissionParams calldata transmissionParams_ - ) internal returns (bool success, bytes memory returnData) { - // check if the gas limit is sufficient - // bump by 5% to account for gas used by current contract execution - - // @audit should we restrict gaslimit to uint64 to prevent overflow/underflow? - if (gasleft() < (executionParams_.gasLimit * gasLimitBuffer) / 100) revert LowGasLimit(); - - // NOTE: external un-trusted call - bool exceededMaxCopy; - // @audit do we need to check if the target is a contract? - // potential risk is, what if a contract connects to socket and use self destruct? - // in this case, .call will return success = true but the call will go to an eoa - (success, exceededMaxCopy, returnData) = executionParams_.target.tryCall( - executionParams_.value, - executionParams_.gasLimit, - maxCopyBytes, - executionParams_.payload - ); -``` - -**Function:** `_execute()` - Internal execution function - -**Issue:** The function doesn't check if `executionParams_.target` is a contract before calling it. If a contract connects to the socket and then self-destructs, subsequent calls would go to an EOA, which might return `success = true` but not execute as expected. This could lead to unexpected behavior. - ---- - -## 4. FastSwitchboard.sol - -### Audit 9: Unauthorized Fee Increase Vulnerability in FastSwitchboard - -**Location:** `contracts/protocol/switchboard/FastSwitchboard.sol:169-171` - -**Context:** - -```163:173:contracts/protocol/switchboard/FastSwitchboard.sol - function increaseFeesForPayload( - bytes32 payloadId_, - address plug_, - bytes calldata feesData_ - ) external payable override onlySocket { - if(msg.value > 0) revert MsgValueNotAllowed(); - // @audit here anyone can connect themselves to a sb and increase fees for random payloadId, hence exhausting a gateway's funds? - // verify plug and payloadId in socket before increasing fees? - // should we revert here or just ignore it for now? - emit FeesIncreased(payloadId_, plug_, feesData_); - } -``` - -**Function:** `increaseFeesForPayload()` - Fee increase function - -**Issue:** This function currently only emits an event and doesn't actually increase fees (FastSwitchboard doesn't support fee increases yet). However, the audit raises concerns about: - -1. **Unauthorized fee increases**: Anyone could connect themselves to a switchboard and call this with random payloadIds, potentially exhausting gateway funds -2. **Verification needed**: Should verify plug and payloadId in socket before allowing fee increases -3. **Behavior decision**: Should the function revert for invalid calls or just ignore them? - -**Note:** The function reverts if `msg.value > 0`, but doesn't validate the `payloadId_` or `plug_` parameters. Since this is a no-op function (only emits event), the concern is about future implementation when fee increases are actually supported. - ---- - -## 5. SocketConfig.sol - -### Audit 10: Switchboard Code Existence Check - -**Location:** `contracts/protocol/SocketConfig.sol:76` - -**Context:** - -```75:90:contracts/protocol/SocketConfig.sol - function registerSwitchboard() external returns (uint32 switchboardId) { - // @audit should we check if the switchboard has code? - switchboardId = switchboardIds[msg.sender]; - if (switchboardId != 0) revert SwitchboardExists(); - - // increment the switchboard id counter - switchboardId = switchboardIdCounter++; - - // set the switchboard id and address - switchboardIds[msg.sender] = switchboardId; - switchboardAddresses[switchboardId] = msg.sender; - - // set the switchboard status to registered - switchboardStatus[switchboardId] = SwitchboardStatus.REGISTERED; - emit SwitchboardAdded(msg.sender, switchboardId); - } -``` - -**Function:** `registerSwitchboard()` - Switchboard registration - -**Issue:** The function doesn't verify that `msg.sender` is a contract with code. An EOA could register itself as a switchboard, which might cause issues when the socket tries to call switchboard functions later. A check using `extcodesize` or `address.code.length > 0` (Solidity 0.8.20+) would prevent this. - ---- - -## 6. Floating Pragma Issue - -### Audit 11: Floating Pragma Across All Protocol Contracts - -**Location:** All protocol contracts (17 files) -**Current Pragma:** `pragma solidity ^0.8.21;` -**Severity:** HIGH -**Risk Level:** CRITICAL - -**Affected Files:** - -- `Socket.sol` -- `SocketConfig.sol` -- `SocketUtils.sol` -- `SocketBatcher.sol` -- `NetworkFeeCollector.sol` -- `switchboard/FastSwitchboard.sol` -- `switchboard/MessageSwitchboard.sol` -- `switchboard/SwitchboardBase.sol` -- `base/PlugBase.sol` -- `base/MessagePlugBase.sol` -- All interface contracts (7 files) - -**Issue:** All 17 contracts in the `contracts/protocol/` directory use floating pragmas (`^0.8.21`), which allows compilation with any Solidity version from 0.8.21 to <0.9.0. This introduces several critical risks: - -1. **Unpredictable Behavior**: Different compiler versions may produce different bytecode, leading to inconsistent behavior across deployments -2. **Security Vulnerabilities**: Newer compiler versions may introduce bugs or change behavior in ways that affect security -3. **Digest Generation Inconsistency**: Critical functions like `_createDigest()` in `SocketUtils` and `MessageSwitchboard` must be deterministic - different compiler versions could encode `abi.encodePacked()` differently -4. **Signature Recovery Variations**: ECDSA signature recovery in `SwitchboardBase._recoverSigner()` could behave differently across versions -5. **Payload ID Generation**: Must be deterministic across all deployments - -**Critical Functions at Risk:** - -- `Socket.execute()` - Core execution logic -- `SocketUtils._createDigest()` - Digest generation for verification -- `MessageSwitchboard._createDigest()` - Digest creation with length prefixes -- `SwitchboardBase._recoverSigner()` - ECDSA signature recovery -- `FastSwitchboard.processPayload()` / `MessageSwitchboard.processPayload()` - Payload ID generation - -**Can Contracts Be Fixed to 0.8.28?** - -**Yes, contracts can be fixed to `pragma solidity 0.8.28;`** (or any specific version within the 0.8.x range). Solidity 0.8.28 was released in October 2024 and includes: - -- Full support for transient storage state variables -- Optimizations that reduce memory usage during compilation -- No breaking changes from 0.8.21 that would affect these contracts - -**Recommendation:** - -1. **Immediate Action**: Lock all pragmas to a specific version: - - ```solidity - pragma solidity 0.8.28; - ``` - - Or after thorough testing, use: - - ```solidity - pragma solidity 0.8.21; // Current minimum - ``` - -2. **Priority Order:** - - - **Critical Priority**: `Socket.sol`, `SocketUtils.sol`, `FastSwitchboard.sol`, `MessageSwitchboard.sol` - - **High Priority**: `SocketConfig.sol`, `SwitchboardBase.sol`, `NetworkFeeCollector.sol` - - **Medium Priority**: All interfaces and base contracts - -3. **Testing Requirements:** - - - Test all contracts with locked pragma version - - Verify digest generation consistency - - Test signature recovery across scenarios - - Validate payload ID generation determinism - - Ensure bytecode matches across environments - -4. **Deployment Considerations:** - - Use same compiler version for all contracts - - Document exact compiler version in deployment scripts - - Verify bytecode matches across testnet and mainnet deployments - -**Reference:** See `internal-audit/done/FLOATING_PRAGMA_AUDIT.md` for detailed analysis. - ---- - -## Summary - -| # | File | Line | Issue Type | Severity | Status | -| --- | ----------------------- | ------- | ------------------ | -------- | ------- | -| 1 | MessageSwitchboard.sol | 218 | Overflow/Underflow | Low | Active | -| 2 | MessageSwitchboard.sol | 442 | Reentrancy | Medium | Active | -| 3 | MessageSwitchboard.sol | 566 | Access Control | Medium | Removed | -| 4 | NetworkFeeCollector.sol | 73 | Access Control | Medium | Active | -| 5 | Socket.sol | 36 | Input Validation | Low | Active | -| 6 | Socket.sol | 52 | Reentrancy | Medium | Active | -| 7 | Socket.sol | 125 | Type Safety | Low | Active | -| 8 | Socket.sol | 130 | Contract Existence | Medium | Active | -| 9 | FastSwitchboard.sol | 169-171 | Access Control | High | Active | -| 10 | SocketConfig.sol | 76 | Contract Existence | Medium | Active | -| 11 | All Protocol Contracts | N/A | Floating Pragma | High | Active | - ---- - -**Total Audit Tags:** 11 (10 active, 1 removed) -**Files Affected:** 17 (for floating pragma) + 6 (for other issues) -**Last Updated:** Generated from protocol contracts diff --git a/PAYLOAD_ID_ARCHITECTURE.md b/PAYLOAD_ID_ARCHITECTURE.md index 2dd23e63..c2e2c665 100644 --- a/PAYLOAD_ID_ARCHITECTURE.md +++ b/PAYLOAD_ID_ARCHITECTURE.md @@ -9,12 +9,12 @@ Unified payload ID structure for all three payload types: Write, Trigger, and Me ### Bit Layout (256 bits total) ``` -[Origin: 64 bits][Verification: 64 bits][Pointer: 64 bits][Reserved: 64 bits] +[Source: 64 bits][Verification: 64 bits][Pointer: 64 bits][Reserved: 64 bits] ``` Each component breakdown: -- **Origin (64 bits)**: `chainSlug (32 bits) | switchboardId/watcherId (32 bits)` +- **Source (64 bits)**: `chainSlug (32 bits) | switchboardId/watcherId (32 bits)` - **Verification (64 bits)**: `chainSlug (32 bits) | switchboardId/watcherId (32 bits)` - **Pointer (64 bits)**: Counter value - **Reserved (64 bits)**: For future extensibility @@ -23,7 +23,7 @@ Each component breakdown: ### 1.

Reentrancy Vulnerability -**Location:** `SocketConfig.connect(uint32,bytes)` (lines 164-169, 521-526, 733-738) -**Issue:** External call to `ISwitchboard.updatePlugConfig()` is made before emitting the `PlugConnected` event. This creates a reentrancy risk where state changes occur after external calls. -**Recommendation:** Follow checks-effects-interactions pattern: emit events before external calls, or use reentrancy guards. - -### 2. Unused Return Value -**Location:** `SocketBatcher.attestAndExecute()` (line 17-18) -**Issue:** The return value from `socket__.execute()` is ignored. If `execute()` returns important status information, this could lead to missed error handling. -**Recommendation:** Check and handle the return value appropriately, or explicitly mark it as intentionally ignored. - -### 3. Ether Locking -**Location:** `SocketConfig` contract (lines 720-731) -**Issue:** Contract has payable functions (via `ISocket` interface) but no withdrawal mechanism. Ether sent to this contract could be permanently locked. -**Recommendation:** Add a withdrawal function or ensure ether is properly forwarded/used in payable functions. - -### 4. Arbitrary Ether Transfer -**Location:** `Socket._handleSuccessfulExecution()` (lines 511-514) -**Issue:** Sends ETH to `networkFeeCollector.collectNetworkFee()` which may be an arbitrary address. -**Recommendation:** Verify that `networkFeeCollector` is a trusted, immutable address, or add proper validation. - -### 5. Block Timestamp Dependency -**Location:** `Socket.execute()` (lines 528-531) -**Issue:** Uses `block.timestamp` for deadline comparison (`executionParams_.deadline < block.timestamp`). -**Recommendation:** Be aware that miners can manipulate timestamps within a small range. Consider if this is acceptable for your use case. - -## 🟡 Medium Priority Issues - -### 6. Unimplemented Interface Functions -**Location:** -- `SocketUtils` (lines 358-363): Missing `execute()`, `executionStatus()`, `payloadIdToDigest()`, `sendPayload()` -- `SocketConfig` (lines 828-835): Missing `chainSlug()`, `execute()`, `executionStatus()`, `increaseFeesForPayload()`, `payloadIdToDigest()`, `sendPayload()` - -**Issue:** Contracts claim to implement `ISocket` interface but are missing required functions. -**Recommendation:** Either implement all interface functions or remove the interface inheritance if not needed. - -### 7. Dead Code -**Location:** Multiple functions identified as unused (lines 280-291, 643-649, 788-796) -**Functions:** -- `AccessControl._checkRole()` -- `SocketUtils._createDigest()` -- `SocketUtils._verifyPayloadId()` -- `convertToSolanaUint64()` -- `createPayloadId()` -- `decodePayloadId()` -- `fromBytes32Format()` -- `getOriginInfo()` -- `getVerificationInfo()` -- `toBytes32Format()` -- `Pausable._pause()` and `_unpause()` - -**Recommendation:** Remove unused code to reduce contract size and improve maintainability, or document why they're kept for future use. - -### 8. Unused State Variables -**Location:** -- `AccessControl._gap_access_control` in `NetworkFeeCollector` and `Socket` (lines 508-509, 717-718) - -**Issue:** Storage gap variable is declared but never used. -**Recommendation:** If this is for upgradeability, ensure it's properly sized. Otherwise, consider removing it. - -## 🟢 Low Priority / Informational - -### 9. Solidity Version Mismatch -**Issue:** Two different Solidity versions used: -- `^0.8.21` in protocol contracts -- `^0.8.4` in solady libraries - -**Note:** This is expected when using external libraries. However, be aware that: -- `^0.8.21` has known issue: `VerbatimInvalidDeduplication` -- `^0.8.4` has multiple known issues (listed in output) - -**Recommendation:** Consider upgrading to newer, more stable versions if possible, or ensure you're aware of the limitations. - -### 10. Naming Conventions -**Location:** -- `SocketBatcher.socket__` (line 126) -- `AccessControl._gap_access_control` (lines 325, 475, 684, 825) - -**Issue:** Variables don't follow mixedCase naming convention. -**Recommendation:** Follow Solidity style guide for consistency. - -### 11. Library Code Findings (Expected) -The following findings are in external library code (solady) and are expected: -- Assembly usage (lines 25-84, 171-254, etc.) -- Write-after-write in `SafeTransferLib.permit2()` (lines 19-23, 159-162, etc.) -- Too many digits in literals (lines 129-157, etc.) - -**Note:** These are informational and expected in optimized library code. - -## Summary Statistics - -- **Security Issues:** 5 critical findings -- **Code Quality:** 3 medium priority issues -- **Informational:** Multiple findings (mostly in libraries) -- **Total Contracts Analyzed:** 55 -- **Total Detectors Run:** 100 - -## Recommended Actions - -1. **Immediate:** Fix reentrancy issue in `SocketConfig.connect()` -2. **High Priority:** Review and fix ether locking in `SocketConfig` -3. **High Priority:** Verify return value handling in `SocketBatcher.attestAndExecute()` -4. **Medium Priority:** Implement missing interface functions or remove interface inheritance -5. **Medium Priority:** Clean up dead code -6. **Low Priority:** Address naming conventions for consistency -

Conclusion - -**Overall Risk Level:** ⚠️ **MEDIUM** - -**Key Findings:** - -- ⚠️ **2 Medium Risk Issues:** ETH transfer reverts in refund paths (mitigated by SELFDESTRUCT) -- ⚠️ **1 Medium Risk Issue:** `gasLimitBuffer` could be set to invalid value -- ⚠️ **1 Low Risk Issue:** External call dependency on fee collector -- ✅ **No Critical Issues:** No balance manipulation or critical division by zero - -**Key Strengths:** - -1. ✅ Uses `forceSafeTransferETH()` with SELFDESTRUCT fallback (prevents most reverts) -2. ✅ Uses `tryCall()` for target execution (handles failures gracefully) -3. ✅ No balance-dependent logic that could be manipulated -4. ✅ Division uses constant denominator (100) - -**Critical Recommendations:** - -1. Add balance checks before ETH transfers -2. Add minimum validation for `gasLimitBuffer` -3.

the modifier ensures it cannot be reached twice. -- `_setOverrides` simply copies calldata into storage for later reads; no extra validation required. -- `initSocket` is gated by `socketInitializer`, preventing repeated registration. - -### `base/MessagePlugBase.sol` - -- Constructor stores the socket address and immediately calls `connect`; requirements are inherited from the socket contract. -- `_registerSibling` pushes configuration through `socket__.updatePlugConfig`, letting the switchboard enforce chain-specific checks. -- `_registerSiblings` verifies array length equality (`ArrayLengthMismatch`) before iterating, so per-call assumptions hold. - -### `NetworkFeeCollector.sol` - -- Constructor grants roles and emits the initial fee change; no unchecked user input. -- `collectNetworkFee` (external, payable) enforces `msg.value >= networkFee` and is role-protected, so insufficient fees revert deterministically. -- `getNetworkFee` is a read-only getter. -- `setNetworkFee` is restricted to governance and emits deltas to keep off-chain replicas consistent. -- `rescueFunds` relies on `RESCUE_ROLE`; RescueFundsLib performs token/ETH transfers with its own checks. - -### `Socket.sol` - -- Constructor simply seeds `gasLimitBuffer`; shared setup happens in `SocketUtils`. -- `execute` validates deadline, call type (`WRITE`), plug registration, `msg.value`, payload ID, execution status, and the switchboard signature chain before invoking user code. -- `_verify` delegates to the switchboard and stores the digest, reverting on failure. -- `_execute` checks available gas against the requested limit (buffered by 5%), then delegates via `LibCall.tryCall`. -- `_handleSuccessfulExecution` emits status and forwards socket fees only when a collector is configured. -- `_handleFailedExecution` marks the payload as `Reverted` and refunds all forwarded funds to either the requester or `refundAddress`. -- `_validateExecutionStatus` guarantees idempotence by blocking second executions unless the prior attempt reverted. -- `sendPayload` and `_sendPayload` both require plugs to be registered before passing control to a switchboard, ensuring only valid relationships exist. -- `fallback` and `receive` either proxy to `_sendPayload` or revert, avoiding accidental ETH acceptance. - -### `SocketBatcher.sol` - -- Constructor stores the socket reference and initializes ownership; no user-controlled inputs. -- `attestAndExecute` fetches the specified switchboard and calls `attest` before `socket__.execute`, maintaining the pre-attestation requirement. -- `rescueFunds` is owner-only and routes through `RescueFundsLib`. - -### `SocketConfig.sol` - -- `registerSwitchboard` prevents duplicate registrations (`SwitchboardExists`) before assigning IDs. -- `disableSwitchboard`/`enableSwitchboard` change status flags under role control so invalid switchboards cannot be selected. -- `setNetworkFeeCollector` updates the collector address atomically via governance. -- `connect` enforces non-zero switchboard IDs and `REGISTERED` status before emitting configuration. -- `updatePlugConfig` requires prior connection; otherwise `PlugNotConnected` reverts. -- `disconnect` clears the switchboard mapping only when the plug was connected. -- `setGasLimitBuffer` and `setMaxCopyBytes` are governance-only, so downstream gas assumptions stay coherent. -- `getPlugConfig`/`getPlugSwitchboard` simply return stored metadata without mutating state. - -### `SocketUtils.sol` - -- Constructor stores the chain slug, hashes the version, and initializes ownership, satisfying immutability requirements. -- `_createDigest` length-prefixes dynamic fields to avoid collision attacks, fulfilling the digest contract. -- `simulate` uses `onlyOffChain` so that on-chain callers cannot consume arbitrary gas or reveal state. -- `_verifyPlugSwitchboard` reverts when plugs are unregistered or tied to disabled switchboards. -- `_verifyPayloadId` ensures the verification metadata embedded in `payloadId` matches the currently authorized switchboard for the target chain. -- `increaseFeesForPayload` first checks that the caller is a registered plug; the downstream switchboard decides whether the fee update is meaningful (finding RV-1 highlights missing logic in the fast switchboard). -- `rescueFunds`, `pause`, and `unpause` each enforce their respective roles so operational requirements remain intact. - -### `switchboard/SwitchboardBase.sol` - -- Constructor pins the socket and chain slug while initializing ownership, preventing later reconfiguration. -- `registerSwitchboard` can only be triggered by the owner and simply proxies to `socket__.registerSwitchboard`. -- `getTransmitter` either recovers a signer from `transmitterSignature_` or returns zero, ensuring downstream callers know whether authentication happened. -- `_recoverSigner` is internal and wraps `ECDSA.recover` with the expected prefix. -- `rescueFunds` is role-guarded. - -### `switchboard/FastSwitchboard.sol` - -- Constructor simply feeds its parameters into `SwitchboardBase`. -- `attest` verifies watchers via `_recoverSigner` and `WATCHER_ROLE`. -- `allowPayload` ensures the source matches `plugAppGatewayIds` before honoring attestations. -- `setEvmxConfig` demands ownership to avoid misconfiguration. -- `processPayload` guards against unset EVMX config, auto-fills missing deadlines, and increments the payload counter safely. -- `increaseFeesForPayload` suffers from RV-1 (no requirement checks or state changes). -- `updatePlugConfig` decodes and stores the `appGatewayId` under socket control. -- `setRevertingPayload` and `setDefaultDeadline` are owner-only toggles. -- `getPlugConfig` returns the stored mapping value; no user input. - -### `switchboard/MessageSwitchboard.sol` - -- Constructor defers to `SwitchboardBase`. -- `setSiblingConfig` requires ownership and writes all three sibling mappings atomically. -- `setRevertingPayload` flips the inherited mapping under owner control. -- `processPayload` enforces override version, sibling existence, min-fee rules, and sponsor approvals before emitting `MessageOutbound`. -- `_decodeOverrides` validates version bytes and supplies default deadlines when omitted. -- `_validateSibling` ensures socket, switchboard, and plug entries exist for the chosen destination chain. -- `_createDigestAndPayloadId` constructs payload IDs deterministically and reverts if the destination switchboard ID is missing. -- `approvePlug`/`approvePlugs` and `revokePlug`/`revokePlugs` manipulate sponsor approvals directly; no user-controlled arithmetic involved. -- `attest` enforces watcher signatures and prevents duplicate attestations. -- `markRefundEligible` requires watcher approval and ensures the payload has refundable fees before flagging eligibility. -- `refund` checks eligibility and idempotence before transferring ETH to the recorded `refundAddress`. -- `setMinMsgValueFees` and `setMinMsgValueFeesBatch` both recover fee-updater signatures (with nonce tracking) and revert on mismatched array lengths. -- `setMinMsgValueFeesOwner` and `setMinMsgValueFeesBatchOwner` give governance a direct override path subject to array length checks. -- `increaseFeesForPayload` delegates to `_increaseNativeFees`/`_increaseSponsoredFees` after decoding the fee type. -- `_increaseNativeFees` and `_increaseSponsoredFees` both confirm that the caller plug matches the payload creator. -- `allowPayload` decodes the source tuple and ensures it matches the registered sibling plug before trusting the attestation. -- `_createDigest` mirrors `_createDigestAndPayloadId`’s encoding strategy to maintain uniqueness guarantees. -- `updatePlugConfig` decodes `(chainSlug, siblingPlug)` and validates sibling sockets/switchboards before storing. -- `getPlugConfig` simply returns the encoded sibling plug for the requested chain. - -## References - -- Requirement validation guidance: [https://kadenzipfel.github.io/smart-contract-vulnerabilities/vulnerabilities/requirement-violation.html](https://kadenzipfel.github.io/smart-contract-vulnerabilities/vulnerabilities/requirement-violation.html) diff --git a/internal-audit/vulnerabilites-checklist/SHADOWING_STATE_VARIABLES_AUDIT.md b/internal-audit/vulnerabilites-checklist/SHADOWING_STATE_VARIABLES_AUDIT.md deleted file mode 100644 index 16e75993..00000000 --- a/internal-audit/vulnerabilites-checklist/SHADOWING_STATE_VARIABLES_AUDIT.md +++ /dev/null @@ -1,429 +0,0 @@ -# Shadowing State Variables Vulnerability Audit Report - -## Protocol Contracts Analysis - -**Date:** 2024 -**Scope:** `contracts/protocol/` directory -**Vulnerability Type:** State Variable Shadowing - ---- - -## Executive Summary - -State variable shadowing occurs when function parameters or local variables share the same name as state variables, creating confusion and potential bugs.

+ +**Answer**: The switchboard architecture provides flexibility and upgradability: + +- **Different Security Models**: Some applications need fast finality (FastSwitchboard), others need stronger guarantees (MessageSwitchboard with multiple watchers) +- **Upgradability**: Can deploy new switchboard types without changing core Socket +- **Competition**: Multiple switchboards can compete on speed, cost, and security +- **Specialization**: Switchboards can be optimized for specific chains or use cases + +The Socket contract remains simple and focused on execution, while switchboards handle the complex verification logic. + +--- + +### Q2: Why are payload IDs structured as bytes32 with encoded information? + +**Answer**: The payload ID structure `[Source: 64 bits][Verification: 64 bits][Counter: 64 bits][Reserved: 64 bits]` provides several benefits: + +- **Self-Describing**: Contains routing information without additional lookups +- **Validation**: Easy to verify payload is for correct chain and switchboard +- **Uniqueness**: Counter ensures global uniqueness across all chains +- **Compact**: Single bytes32 is gas-efficient for storage and events +- **Future-Proof**: Reserved 64 bits for future extensions + +See `PAYLOAD_ID_ARCHITECTURE.md` for detailed explanation. + +--- + +### Q3: Why can payloads only be executed once, even if they fail? + +**Answer**: This is an intentional design choice: + +- **Simplicity**: Prevents complex retry logic and state management +- **Determinism**: Clear finality - each payload has one outcome +- **Security**: Prevents replay attacks and complex re-execution scenarios +- **Gas Efficiency**: No need to track retry counts or conditions + +If a payload fails due to temporary conditions, the application layer can: +- Send a new payload with updated parameters +- Use the refund mechanism (MessageSwitchboard) +- Build retry logic in the plug contract itself + +--- + +### Q4: What's the difference between FastSwitchboard and MessageSwitchboard? + +**Answer**: + +**FastSwitchboard**: +- Optimized for speed via EVMX verification +- Simpler fee model (fees managed on EVMX) +- App gateway ID-based routing +- Single watcher per payload (EVMX consensus) +- Best for: High-throughput, fast finality needs + +**MessageSwitchboard**: +- Full-featured with native and sponsored fees +- Complex fee management with refunds +- Sibling plug mapping for routing +- Multiple watchers possible (more decentralized) +- Best for: Applications needing refunds, complex fee logic + +--- + +### Q5: Why does the fallback function double-encode the return value? + +**Answer**: Due to Solidity's behavior with fallback functions: + +```solidity +fallback(bytes calldata) external payable returns (bytes memory) { + bytes32 payloadId = _sendPayload(...); + return abi.encode(abi.encode(payloadId)); // Double encoding +} +``` + +- Raw calldata → raw returndata (no ABI encoding by Solidity) +- `abi.encode(payloadId)` converts bytes32 → bytes +- Outer `abi.encode()` adds offset + length for proper ABI decoding +- Alternative: Use `sendPayload()` directly for standard encoding + +This maintains compatibility with raw calls while providing proper ABI-decodable returns. + +--- + +## Security & Trust + +### Q6: What happens if a watcher is compromised? + +**Answer**: Impact depends on the switchboard type: + +**FastSwitchboard**: +- Single compromised watcher can attest malicious payloads +- Relies on EVMX chain consensus (multiple validators) +- System security = EVMX security + +**MessageSwitchboard**: +- Can configure multiple watchers (M-of-N threshold) +- Single compromised watcher cannot authorize alone +- System security depends on watcher set size and threshold + +**Mitigation Strategies**: +- Use multiple independent watcher nodes +- Implement watcher rotation +- Monitor watcher behavior off-chain +- Enable governance to disable compromised switchboards + +--- + +### Q7: Can the Socket owner or governance steal user funds? + +**Answer**: No, for several reasons: + +**What Governance CAN do**: +- Pause the contract (prevents new operations) +- Disable switchboards (prevents new connections) +- Change network fee collector +- Update gas/copy byte limits + +**What Governance CANNOT do**: +- Modify past execution status +- Change payloadIdToDigest mappings +- Execute payloads without valid attestation +- Access user funds directly +- Cancel attested payloads + +User funds are protected by: +- Immutable execution logic +- Cryptographic attestation requirements +- Replay protection +- Source validation in switchboards + +**Worst Case Scenario**: Governance could DOS the system by pausing, but cannot steal funds. + +--- + +### Q8: What prevents a malicious plug from attacking the system? + +**Answer**: Multiple layers of protection: + +**Isolation**: +- External call via tryCall with gas limit +- Return data limited to maxCopyBytes +- Value transfer limited to executionParams.value + +**State Protection**: +- Execution status set BEFORE plug call +- Digest stored BEFORE plug call +- Reentrancy guard (recommended) + +**Economic Disincentives**: +- Malicious behavior only affects the malicious plug +- Cannot impact other plugs' payloads +- Reverting payloads lose fees (fail to execute) + +**What Malicious Plug Can Do**: +- Revert its own executions +- Consume all provided gas +- Attempt reentrancy (should fail) + +**What Malicious Plug Cannot Do**: +- Execute payloads multiple times +- Access other plugs' funds +- Forge attestations +- Bypass verification + +--- + +### Q9: How are cross-chain signature replays prevented? + +**Answer**: Multiple mechanisms: + +**In Signature Digest**: +```solidity +digest = keccak256(abi.encodePacked( + toBytes32Format(address(this)), // Contract address + chainSlug, // Chain identifier + // ... other parameters +)) +``` + +**Protection Layers**: +1. **Contract Address**: Different addresses on different chains +2. **Chain Slug**: Explicit chain identifier in signature +3. **Payload ID**: Includes source and destination chain info +4. **Nonces**: Prevent replay within same chain + +**Note**: If same switchboard deployed at same address on multiple chains with same chainSlug (admin error), signatures could theoretically replay. Recommended to also include `block.chainid` for additional protection. + +--- + +## Operations & Behavior + +### Q10: What happens if a payload deadline passes before execution? + +**Answer**: + +**Before Execution Starts**: +```solidity +if (executionParams_.deadline < block.timestamp) revert DeadlinePassed(); +``` +- Payload cannot be executed +- Reverts immediately +- Funds not lost (not yet transferred) + +**During Execution**: +- Deadline not checked during plug execution +- Payload could finish slightly after deadline + +**After Deadline**: +- Payload remains unexecutable +- In MessageSwitchboard: Eligible for refund (watcher must mark) +- In FastSwitchboard: Fees not refunded (managed on EVMX) + +**Best Practice**: Set deadlines with sufficient buffer (default 1 day) + +--- + +### Q11: Can payload execution order be controlled? + +**Answer**: No, by design: + +**Current Behavior**: +- Payloads can be executed in any order +- First transmitter to call execute() wins +- `prevBatchDigestHash` exists in params but not enforced + +**Why Not Enforced**: +- Cross-chain messaging is inherently async +- Different chain finality times +- Transmitter competition for fees +- Simpler implementation + +**Application-Level Solutions**: +- Plugs should handle out-of-order messages +- Use nonces/sequence numbers in payload data +- Build state machines that accept messages in any order +- Use `prevBatchDigestHash` for optional ordering + +--- + +### Q12: How do refunds work in MessageSwitchboard? + +**Answer**: Two-step process: + +**Step 1: Mark Eligible** +```solidity +messageSwitchboard.markRefundEligible(payloadId, nonce, signature) +``` +- Requires watcher signature +- Watcher verifies payload won't execute (e.g., deadline passed) +- Sets `isRefundEligible = true` + +**Step 2: Claim Refund** +```solidity +messageSwitchboard.refund(payloadId) +``` +- Anyone can call (if eligible) +- Protected by ReentrancyGuard +- Transfers nativeFees to refundAddress +- Sets `isRefunded = true` + +**Conditions for Eligibility**: +- Payload has not executed +- Deadline passed or other non-executable condition +- Watcher has attested to eligibility + +**Security**: Two-step process prevents unauthorized refunds + +--- + +### Q13: What is the purpose of transmitterProof? + +**Answer**: Optional accountability mechanism: + +**If Provided**: +- Signature over (socket address + payloadId) +- Proves which transmitter delivered payload +- Enables reputation systems +- Allows dispute resolution + +**If Not Provided** (empty bytes): +- Returns address(0) +- Execution still works +- Anonymous delivery + +**Use Cases**: +- Track transmitter performance +- Reward reliable transmitters +- Slash misbehaving transmitters (off-chain) +- Audit trail for executed payloads + +**Note**: Transmitter signature does NOT affect authorization - only attestation matters. + +--- + +### Q14: Why is there a gasLimitBuffer? + +**Answer**: Accounts for contract execution overhead: + +```solidity +// User specifies gasLimit for plug execution +executionParams.gasLimit = 200_000; + +// Socket needs extra gas for its own operations: +// - Verification logic +// - State updates +// - Event emissions +// - Fee collection + +requiredGas = (200_000 * 105) / 100 = 210_000 +``` + +**Default Buffer**: 105 (5% overhead) + +**Why Needed**: +- Socket operations consume gas before/after plug call +- Prevents "out of gas" errors in Socket logic +- Ensures clean error handling + +**Configurable**: Governance can adjust via `setGasLimitBuffer()` + +--- + +## Fees & Economics + +### Q15: How are fees distributed? + +**Answer**: Depends on switchboard type: + +**MessageSwitchboard (Native Fees)**: +``` +User pays: msg.value +├─ executionParams.value → Plug +├─ transmissionParams.socketFees → NetworkFeeCollector +└─ Remainder stays in MessageSwitchboard (excess/refund) +``` + +**MessageSwitchboard (Sponsored)**: +``` +User pays: 0 ETH (msg.value = 0) +Sponsor: Pre-approved plug, maxFees tracked off-chain +Fees: Managed by off-chain system, charged to sponsor +``` + +**FastSwitchboard**: +``` +Fees: Managed entirely on EVMX chain +Socket/FastSwitchboard: No fee handling +``` + +--- + +### Q16: Can fees be increased after payload is created? + +**Answer**: Yes, via `increaseFeesForPayload()`: + +**Purpose**: +- Incentivize slow payloads +- Increase priority +- Adjust for changing gas prices + +**Restrictions**: +- Only the source plug can increase fees +- Can only increase, not decrease +- Native fees: Add more ETH +- Sponsored fees: Update maxFees value + +**Effect**: +- Does not invalidate attestation +- Off-chain watchers/transmitters see updated fees +- Makes execution more attractive + +--- + +### Q17: What prevents fee manipulation or theft? + +**Answer**: Multiple safeguards: + +**Fee Storage**: +```solidity +struct PayloadFees { + uint256 nativeFees; // Immutable except increase/refund + address refundAddress; // Set at creation + bool isRefundEligible; // Only watcher can set + bool isRefunded; // One-time flag + address plug; // Ownership tracking +} +``` + +**Protections**: +1. Only source plug can increase fees +2. Refunds only to specified refundAddress +3. Refunds only when watcher-approved +4. Refunds only possible once +5. Fees in successful execution go to NetworkFeeCollector (governance-set) + +**Cannot**: +- Decrease fees +- Redirect refund address +- Claim refund without watcher signature +- Double refund + +--- + +### Q18: What happens to excess msg.value? + +**Answer**: + +**On Successful Execution**: +```solidity +msg.value = executionParams.value + socketFees + excess +├─ executionParams.value → Plug +├─ socketFees → NetworkFeeCollector +└─ excess → Stays in Socket contract ⚠️ +``` + +**On Failed Execution**: +```solidity +msg.value (all) → Refunded to refundAddress +``` + +**Recommendation**: +- Send exact amount (value + socketFees) +- Or accept that excess stays in Socket +- Use `rescueFunds()` if significant amounts stuck + +**Design Note**: Consider adding excess refund in future version + +--- + +## Technical Details + +### Q19: Why use length prefixes in digest creation? + +**Answer**: Prevents collision attacks: + +**Without Length Prefixes**: +```solidity +// Collision possible: +payload1 = "AAAA", source1 = "BB" +payload2 = "AAA", source2 = "ABB" +// Both hash to same: keccak256("AAAABB") +``` + +**With Length Prefixes**: +```solidity +// Unique hashes: +digest1 = keccak256(uint32(4) + "AAAA" + uint32(2) + "BB") +digest2 = keccak256(uint32(3) + "AAA" + uint32(3) + "ABB") +``` + +**Applied To**: +- payload (variable length) +- source (variable length) +- extraData (variable length) + +**Fixed-Size Fields**: Don't need prefixes (deadline, gasLimit, etc.) + +--- + +### Q20: What is maxCopyBytes and why limit return data? + +**Answer**: Security mechanism against DOS: + +**Problem**: +```solidity +// Malicious plug returns huge data +return new bytes(10_000_000); // Would consume excessive gas to copy +``` + +**Solution**: +```solidity +maxCopyBytes = 2048; // Default 2KB + +(success, exceededMaxCopy, returnData) = target.tryCall(..., maxCopyBytes, ...) +// If return data > 2KB: +// - exceededMaxCopy = true +// - returnData = first 2KB only +``` + +**Benefits**: +- Prevents DOS via excessive memory allocation +- Predictable gas costs +- Still allows reasonable return data + +**Configurable**: Governance can update via `setMaxCopyBytes()` + +--- + +### Q21: How does tryCall work and why use it? + +**Answer**: Solady's tryCall provides safe external call handling: + +**Features**: +```solidity +(bool success, bool exceededMaxCopy, bytes memory returnData) = + target.tryCall(value, gasLimit, maxCopyBytes, payload); +``` + +**Advantages over raw call**: +- Explicit gas limit forwarding +- Return data size limiting (DOS protection) +- Doesn't revert on failure (returns success flag) +- Safely handles all failure modes + +**Why Not Raw Call**: +```solidity +(bool success, bytes memory data) = target.call{value: value, gas: gasLimit}(payload); +// Issues: +// - No return data limiting +// - Could copy unbounded data +// - Less explicit gas handling +``` + +--- + +### Q22: What is the significance of WRITE/READ/SCHEDULE call types? + +**Answer**: Call types define execution context: + +**WRITE** (Currently Only Supported): +- State-changing operations +- Executed on destination chain +- Default for cross-chain messages + +**READ** (Not Yet Implemented): +- View/pure functions +- Would read state without changes +- Planned for future versions + +**SCHEDULE** (Not Yet Implemented): +- Delayed execution +- Would schedule for future block +- Planned for EVMX integration + +**Current Check**: +```solidity +if (executionParams_.callType != WRITE) revert InvalidCallType(); +``` + +**Future**: Additional call types may be supported + +--- + +### Q23: Why is Socket immutable for chainSlug? + +**Answer**: Fundamental identity: + +```solidity +uint32 public immutable chainSlug; +``` + +**Reasons**: +- Each Socket instance tied to specific chain +- Cannot migrate Socket to different chain +- Prevents misconfiguration +- Ensures payload routing integrity +- Gas optimization (immutable vs storage) + +**If Chain Slug Needs to Change**: +- Deploy new Socket contract +- Cannot modify existing deployment +- By design - prevents critical errors + +--- + +## Edge Cases & Scenarios + +### Q24: What happens if a plug connects then immediately disconnects? + +**Answer**: + +**State After Disconnect**: +```solidity +plugSwitchboardIds[plug] = 0; // Cleared in Socket +// But: switchboard still has plug config stored +``` + +**Implications**: +- Cannot send new payloads (not connected) +- Existing attested payloads still executable +- Switchboard retains config (stale data) + +**Cleanup**: +- Switchboard config not automatically cleared +- May want to call `updatePlugConfig(plug, "")` to clear +- Low impact - just storage inefficiency + +--- + +### Q25: Can a switchboard be disabled while plugs are connected? + +**Answer**: Yes, and it's an intended emergency mechanism: + +**Process**: +```solidity +socketConfig.disableSwitchboard(switchboardId); +// Status: REGISTERED → DISABLED +``` + +**Effect on Connected Plugs**: +- Plugs remain connected (mapping not cleared) +- New payloads fail (processPayload checks status) +- Existing attested payloads still executable +- Plugs must manually disconnect and reconnect elsewhere + +**Purpose**: Emergency stop for compromised switchboards + +**Recovery**: Plugs should monitor switchboard status and disconnect if disabled + +--- + +### Q26: What if EVMX chain itself has issues?

CEI pattern is sufficient. - ---- - -### Q6: What happens if a watcher is compromised? - -**Answer**: Impact depends on the switchboard type: - -**FastSwitchboard**: - -- Single compromised watcher can attest malicious payloads -- Relies on EVMX chain consensus (multiple validators) -- System security = EVMX security - -**MessageSwitchboard**: - -- Can configure multiple watchers (M-of-N threshold) -- Single compromised watcher cannot authorize alone -- System security depends on watcher set size and threshold - -**Mitigation Strategies**: - -- Use multiple independent watcher nodes -- Implement watcher rotation -- Monitor watcher behavior off-chain -- Enable governance to disable compromised switchboards - ---- - -### Q7: Can the Socket owner or governance steal user funds? - -**Answer**: No, for several reasons: - -**What Governance CAN do**: - -- Pause the contract (prevents new operations) -- Disable switchboards (prevents new connections) -- Change network fee collector -- Update gas/copy byte limits - -**What Governance CANNOT do**: - -- Modify past execution status -- Change payloadIdToDigest mappings -- Execute payloads without valid attestation -- Access user funds directly -- Cancel attested payloads - -User funds are protected by: - -- Immutable execution logic -- Cryptographic attestation requirements -- Replay protection -- Source validation in switchboards - -**Worst Case Scenario**: Governance could DOS the system by pausing, but cannot steal funds. - ---- - -### Q8: What prevents a malicious plug from attacking the system? - -**Answer**: Multiple layers of protection: - -**Isolation**: - -- External call via tryCall with gas limit -- Return data limited to maxCopyBytes -- Value transfer limited to executionParams.value - -**State Protection**: - -- Execution status set BEFORE plug call -- Digest stored BEFORE plug call -- Reentrancy guard (recommended) - -**Economic Disincentives**: - -- Malicious behavior only affects the malicious plug -- Cannot impact other plugs' payloads -- Reverting payloads lose fees (fail to execute) - -**What Malicious Plug Can Do**: - -- Revert its own executions -- Consume all provided gas -- Attempt reentrancy (should fail) - -**What Malicious Plug Cannot Do**: - -- Execute payloads multiple times -- Access other plugs' funds -- Forge attestations -- Bypass verification - ---- - -### Q9: How are cross-chain signature replays prevented? - -**Answer**: Multiple mechanisms: - -**In Signature Digest**: - -```solidity -digest = keccak256(abi.encodePacked( - toBytes32Format(address(this)), // Contract address - chainSlug, // Chain identifier - // ... other parameters -)) -``` - -**Protection Layers**: - -1. **Contract Address**: Different addresses on different chains -2. **Chain Slug**: Explicit chain identifier in signature -3. **Payload ID**: Includes source and destination chain info -4. **Nonces**: Prevent replay within same chain - -**Note**: If same switchboard deployed at same address on multiple chains with same chainSlug (admin error), signatures could theoretically replay. Recommended to also include `block.chainid` for additional protection. - ---- - -## Operations & Behavior - -### Q10: What happens if a payload deadline passes before execution? - -**Answer**: - -**Before Execution Starts**: - -```solidity -if (executionParams_.deadline < block.timestamp) revert DeadlinePassed(); -``` - -- Payload cannot be executed -- Reverts immediately -- Funds not lost (not yet transferred) - -**During Execution**: - -- Deadline not checked during plug execution -- Payload could finish slightly after deadline - -**After Deadline**: - -- Payload remains unexecutable -- In MessageSwitchboard: Eligible for refund (watcher must mark) -- In FastSwitchboard: Fees not refunded (managed on EVMX) - -**Best Practice**: Set deadlines with sufficient buffer (default 1 day) - ---- - -### Q11: Can payload execution order be controlled? - -**Answer**: No, by design: - -**Current Behavior**: - -- Payloads can be executed in any order -- First transmitter to call execute() wins -- `prevBatchDigestHash` exists in params but not enforced - -**Why Not Enforced**: - -- Cross-chain messaging is inherently async -- Different chain finality times -- Transmitter competition for fees -- Simpler implementation - -**Application-Level Solutions**: - -- Plugs should handle out-of-order messages -- Use nonces/sequence numbers in payload data -- Build state machines that accept messages in any order -- Use `prevBatchDigestHash` for optional ordering - ---- - -### Q12: How do refunds work in MessageSwitchboard? - -**Answer**: Two-step process: - -**Step 1: Mark Eligible** - -```solidity -messageSwitchboard.markRefundEligible(payloadId, nonce, signature) -``` - -- Requires watcher signature -- Watcher verifies payload won't execute (e.g., deadline passed) -- Sets `isRefundEligible = true` - -**Step 2: Claim Refund** - -```solidity -messageSwitchboard.refund(payloadId) -``` - -- Anyone can call (if eligible) -- Protected by ReentrancyGuard -- Transfers nativeFees to refundAddress -- Sets `isRefunded = true` - -**Conditions for Eligibility**: - -- Payload has not executed -- Deadline passed or other non-executable condition -- Watcher has attested to eligibility - -**Security**: Two-step process prevents unauthorized refunds - ---- - -### Q13: What is the purpose of transmitterProof? - -**Answer**: Optional accountability mechanism: - -**If Provided**: - -- Signature over (socket address + payloadId) -- Proves which transmitter delivered payload -- Enables reputation systems -- Allows dispute resolution - -**If Not Provided** (empty bytes): - -- Returns address(0) -- Execution still works -- Anonymous delivery - -**Use Cases**: - -- Track transmitter performance -- Reward reliable transmitters -- Slash misbehaving transmitters (off-chain) -- Audit trail for executed payloads - -**Note**: Transmitter signature does NOT affect authorization - only attestation matters. - ---- - -### Q13A: Why is gasLimit uint64 instead of uint256? - -**Answer**: To prevent overflow issues while maintaining flexibility: - -**With uint64**: - -- Max value: 18,446,744,073,709,551,616 (18 quintillion) -- Calculation: `uint64.max * 105 / 100` fits within uint256 ✓ -- Supports high-throughput chains (Ethereum: 30M, Mantle: 4B for ERC20) -- Prevents type(uint256).max attacks - -**Why No Hardcoded Max**: - -- Different chains have vastly different gas models -- Future chains may have even higher limits -- Natural failure if insufficient gas provided -- Allows protocol flexibility across diverse ecosystems - -**Overflow Safety**: Solidity 0.8+ prevents overflow with revert ✓ - ---- - -### Q13B: Are race conditions possible in blockchain execution? - -**Answer**: Not concurrent races, but transaction ordering matters. - -**Concurrent Execution**: ❌ Impossible - -- Transactions execute serially within a block -- No parallel thread execution -- State changes are atomic per transaction - -**Transaction Ordering**: ✓ Possible - -``` -Block N contains: - Tx1: plug.connect(switchboardId) - Tx2: governance.disableSwitchboard(switchboardId) -``` - -**Execution Order**: - -- If Tx1 first: plug connects, then switchboard disabled (plug can disconnect) -- If Tx2 first: switchboard disabled, plug connection fails - -**Impact**: Minimal - clear state after block, no undefined behavior - -**Note**: This is NOT a race condition in the traditional concurrent programming sense. - ---- - -### Q14: Why is there a gasLimitBuffer? - -**Answer**: Accounts for contract execution overhead: - -```solidity -// User specifies gasLimit for plug execution -executionParams.gasLimit = 200_000; - -// Socket needs extra gas for its own operations: -// - Verification logic -// - State updates -// - Event emissions -// - Fee collection - -requiredGas = (200_000 * 105) / 100 = 210_000 -``` - -**Default Buffer**: 105 (5% overhead) - -**Why Needed**: - -- Socket operations consume gas before/after plug call -- Prevents "out of gas" errors in Socket logic -- Ensures clean error handling - -**Configurable**: Governance can adjust via `setGasLimitBuffer()` - ---- - -## Fees & Economics - -### Q15: How are fees distributed? - -**Answer**: Depends on switchboard type: - -**MessageSwitchboard (Native Fees)**: - -``` -User pays: msg.value -├─ executionParams.value → Plug -├─ transmissionParams.socketFees → NetworkFeeCollector -└─ Remainder stays in MessageSwitchboard (excess/refund) -``` - -**MessageSwitchboard (Sponsored)**: - -``` -User pays: 0 ETH (msg.value = 0) -Sponsor: Pre-approved plug, maxFees tracked off-chain -Fees: Managed by off-chain system, charged to sponsor -``` - -**FastSwitchboard**: - -``` -Fees: Managed entirely on EVMX chain -Socket/FastSwitchboard: No fee handling -``` - ---- - -### Q16: Can fees be increased after payload is created? - -**Answer**: Yes, via `increaseFeesForPayload()`: - -**Purpose**: - -- Incentivize slow payloads -- Increase priority -- Adjust for changing gas prices - -**Restrictions**: - -- Only the source plug can increase fees -- Can only increase, not decrease -- Native fees: Add more ETH -- Sponsored fees: Update maxFees value - -**Effect**: - -- Does not invalidate attestation -- Off-chain watchers/transmitters see updated fees -- Makes execution more attractive - ---- - -### Q16A: How does nonce namespace isolation work? - -**Answer**: Function selectors create isolated nonce spaces to prevent cross-function replay. - -**Implementation**: - -```solidity -function _validateAndUseNonce( - bytes4 selector_, // Function selector for namespace - address signer_, - uint256 nonce_ -) internal { - // Namespace nonce with function selector - uint256 namespacedNonce = uint256(keccak256(abi.encodePacked(selector_, nonce_))); - if (usedNonces[signer_][namespacedNonce]) revert NonceAlreadyUsed(); - usedNonces[signer_][namespacedNonce] = true; -} -``` - -**Usage**: - -```solidity -// Different functions, different namespaces -_validateAndUseNonce(this.markRefundEligible.selector, watcher, nonce); -_validateAndUseNonce(this.setMinMsgValueFees.selector, feeUpdater, nonce); -``` - -**Benefits**: - -- ✓ Same nonce value can be used across different functions -- ✓ Prevents accidental cross-function replay -- ✓ Cleaner off-chain nonce management -- ✓ Function selectors are deterministic (on-chain and off-chain) - -**Off-Chain Nonce Generation**: Uses UUIDv4 (128-bit) for collision resistance - ---- - -### Q16B: Why use function selectors instead of strings for namespaces? - -**Answer**: Deterministic encoding and gas efficiency. - -**Problem with Strings**: - -- Encoding can differ between Solidity and off-chain code -- Variable length increases gas cost -- Potential for encoding mismatches - -**Benefits of Function Selectors**: - -- ✓ Fixed size (bytes4 = 4 bytes) -- ✓ Deterministically computed: `keccak256("functionName(params)")[:4]` -- ✓ Same computation on-chain and off-chain -- ✓ Type-safe (compiler ensures function exists) -- ✓ Lower gas cost - -**Example**: - -```javascript -// Off-chain (JavaScript/TypeScript) -const selector = ethers.utils.id('markRefundEligible(bytes32,uint256,bytes)').slice(0, 10); -const namespacedNonce = ethers.utils.keccak256( - ethers.utils.solidityPack(['bytes4', 'uint256'], [selector, nonce]), -); -``` - ---- - -### Q17: What prevents fee manipulation or theft? - -**Answer**: Multiple safeguards: - -**Fee Storage**: - -```solidity -struct PayloadFees { - uint256 nativeFees; // Immutable except increase/refund - address refundAddress; // Set at creation - bool isRefundEligible; // Only watcher can set - bool isRefunded; // One-time flag - address plug; // Ownership tracking -} -``` - -**Protections**: - -1. Only source plug can increase fees -2. Refunds only to specified refundAddress -3. Refunds only when watcher-approved -4. Refunds only possible once -5. Fees in successful execution go to NetworkFeeCollector (governance-set) - -**Cannot**: - -- Decrease fees -- Redirect refund address -- Claim refund without watcher signature -- Double refund - ---- - -### Q18: What happens to excess msg.value? - -**Answer**: - -**On Successful Execution**: - -```solidity -msg.value = executionParams.value + socketFees + excess -├─ executionParams.value → Plug -├─ socketFees → NetworkFeeCollector -└─ excess → Stays in Socket contract ⚠️ -``` - -**On Failed Execution**: - -```solidity -msg.value (all) → Refunded to refundAddress -``` - -**Recommendation**: - -- Send exact amount (value + socketFees) -- Or accept that excess stays in Socket -- Use `rescueFunds()` if significant amounts stuck - -**Design Note**: Consider adding excess refund in future version - ---- - -## Technical Details - -### Q19: Why use length prefixes in digest creation? - -**Answer**: Prevents collision attacks: - -**Without Length Prefixes**: - -```solidity -// Collision possible: -payload1 = "AAAA", source1 = "BB" -payload2 = "AAA", source2 = "ABB" -// Both hash to same: keccak256("AAAABB") -``` - -**With Length Prefixes**: - -```solidity -// Unique hashes: -digest1 = keccak256(uint32(4) + "AAAA" + uint32(2) + "BB") -digest2 = keccak256(uint32(3) + "AAA" + uint32(3) + "ABB") -``` - -**Applied To**: - -- payload (variable length) -- source (variable length) -- extraData (variable length) - -**Fixed-Size Fields**: Don't need prefixes (deadline, gasLimit, etc.) - ---- - -### Q20: What is maxCopyBytes and why limit return data? - -**Answer**: Security mechanism against DOS: - -**Problem**: - -```solidity -// Malicious plug returns huge data -return new bytes(10_000_000); // Would consume excessive gas to copy -``` - -**Solution**: - -```solidity -maxCopyBytes = 2048; // Default 2KB - -(success, exceededMaxCopy, returnData) = target.tryCall(..., maxCopyBytes, ...) -// If return data > 2KB: -// - exceededMaxCopy = true -// - returnData = first 2KB only -``` - -**Benefits**: - -- Prevents DOS via excessive memory allocation -- Predictable gas costs -- Still allows reasonable return data - -**Configurable**: Governance can update via `setMaxCopyBytes()` - ---- - -### Q21: How does tryCall work and why use it? - -**Answer**: Solady's tryCall provides safe external call handling: - -**Features**: - -```solidity -(bool success, bool exceededMaxCopy, bytes memory returnData) = - target.tryCall(value, gasLimit, maxCopyBytes, payload); -``` - -**Advantages over raw call**: - -- Explicit gas limit forwarding -- Return data size limiting (DOS protection) -- Doesn't revert on failure (returns success flag) -- Safely handles all failure modes - -**Why Not Raw Call**: - -```solidity -(bool success, bytes memory data) = target.call{value: value, gas: gasLimit}(payload); -// Issues: -// - No return data limiting -// - Could copy unbounded data -// - Less explicit gas handling -``` - ---- - -### Q22: What is the significance of WRITE/READ/SCHEDULE call types? - -**Answer**: Call types define execution context: - -**WRITE** (Currently Only Supported): - -- State-changing operations -- Executed on destination chain -- Default for cross-chain messages - -**READ** (Not Yet Implemented): - -- View/pure functions -- Would read state without changes -- Planned for future versions - -**SCHEDULE** (Not Yet Implemented): - -- Delayed execution -- Would schedule for future block -- Planned for EVMX integration - -**Current Check**: - -```solidity -if (executionParams_.callType != WRITE) revert InvalidCallType(); -``` - -**Future**: Additional call types may be supported - ---- - -### Q23: Why is Socket immutable for chainSlug? - -**Answer**: Fundamental identity: - -```solidity -uint32 public immutable chainSlug; -``` - -**Reasons**: - -- Each Socket instance tied to specific chain -- Cannot migrate Socket to different chain -- Prevents misconfiguration -- Ensures payload routing integrity -- Gas optimization (immutable vs storage) - -**If Chain Slug Needs to Change**: - -- Deploy new Socket contract -- Cannot modify existing deployment -- By design - prevents critical errors - ---- - -## Edge Cases & Scenarios - -### Q24: What happens if a plug connects then immediately disconnects? - -**Answer**: - -**State After Disconnect**: - -```solidity -plugSwitchboardIds[plug] = 0; // Cleared in Socket -// But: switchboard still has plug config stored -``` - -**Implications**: - -- Cannot send new payloads (not connected) -- Existing attested payloads still executable -- Switchboard retains config (stale data) - -**Cleanup**: - -- Switchboard config not automatically cleared -- May want to call `updatePlugConfig(plug, "")` to clear -- Low impact - just storage inefficiency - ---- - -### Q25: Can a switchboard be disabled while plugs are connected? - -**Answer**: Yes, and it's an intended emergency mechanism: - -**Process**: - -```solidity -socketConfig.disableSwitchboard(switchboardId); -// Status: REGISTERED → DISABLED -``` - -**Effect on Connected Plugs**: - -- Plugs remain connected (mapping not cleared) -- New payloads fail (processPayload checks status) -- Existing attested payloads still executable -- Plugs must manually disconnect and reconnect elsewhere - -**Purpose**: Emergency stop for compromised switchboards - -**Recovery**: Plugs should monitor switchboard status and disconnect if disabled - ---- - -### Q26: What if EVMX chain itself has issues? - -**Answer**: Impacts FastSwitchboard only: - -**Scenario**: EVMX chain offline or compromised - -**Impact**: - -- FastSwitchboard payloads cannot be attested -- MessageSwitchboard unaffected (independent) -- Plugs can disconnect from FastSwitchboard -- Can connect to MessageSwitchboard instead - -**Mitigation**: - -- Deploy multiple switchboard types -- Don't rely solely on FastSwitchboard -- Have fallback verification method - -**Design Benefit**: Switchboard modularity allows failover - ---- - -### Q27: What happens at payload counter overflow? - -**Answer**: - -**Scenario**: `payloadCounter = type(uint64).max`, then processPayload() called - -**Behavior**: - -```solidity -payloadCounter++ // Overflows in Solidity 0.8+ -// Reverts with panic(0x11) - arithmetic overflow -``` - -**Impact**: - -- Cannot create new payloads on this switchboard -- DOS condition -- Existing payloads unaffected - -**Likelihood**: - -- 2^64 = 18,446,744,073,709,551,616 payloads needed -- At 1000 payloads/second = 584 million years - -**Practical**: Not a realistic concern for any deployment - ---- - -## Integration Questions - -### Q28: How should plugs handle out-of-order message delivery? - -**Answer**: Design patterns: - -**Pattern 1: Idempotent Operations** - -```solidity -// Make operations safe to replay -function inbound(bytes memory data) external { - (uint256 id, ...) = abi.decode(data, (uint256, ...)); - if (processed[id]) return; // Already processed - processed[id] = true; - // ... process -} -``` - -**Pattern 2: Sequence Numbers** - -```solidity -uint256 public expectedNonce; -function inbound(bytes memory data) external { - (uint256 nonce, ...) = abi.decode(data, (uint256, ...)); - if (nonce < expectedNonce) revert AlreadyProcessed(); - if (nonce > expectedNonce) revert OutOfOrder(); - expectedNonce++; - // ... process -} -``` - -**Pattern 3: State Machine** - -```solidity -enum State { A, B, C } -State public state; - -function inbound(bytes memory data) external { - State requiredState = abi.decode(data, (State)); - require(state == requiredState, "Invalid state"); - // ... process and transition -} -``` - ---- - -### Q29: How to estimate gas for cross-chain calls? - -**Answer**: Multi-step process: - -**Step 1: Simulate on Destination** - -```solidity -// Off-chain: Call Socket.simulate() on destination chain -SimulateParams[] memory params = [...]; -SimulationResult[] memory results = socket.simulate(params); -// Get actual gas used + success/failure -``` - -**Step 2: Add Safety Buffer** - -```solidity -uint256 estimatedGas = results[0].gasUsed; -uint256 gasLimit = (estimatedGas * 150) / 100; // 50% buffer -``` - -**Step 3: Include in Overrides** - -```solidity -bytes memory overrides = abi.encode( - version, - dstChainSlug, - gasLimit, // From estimation - value, - ... -); -socket.sendPayload{value: fees + value}(overrides, payload); -``` - -**Best Practices**: - -- Always add buffer (at least 20%) -- Test on destination chain -- Monitor actual vs estimated -- Adjust based on historical data - ---- - -### Q30: Can Socket work with non-EVM chains? - -**Answer**: Partially: - -**Source Chain** (Non-EVM → EVM): - -- Possible with appropriate switchboard -- Switchboard must verify non-EVM chain proofs -- Source encoding in bytes format - -**Destination Chain** (EVM → Non-EVM): - -- Socket must be on EVM chain -- Target must be EVM contract -- Current: EVM-only execution - -**Solana Support**: - -- Structs defined for Solana integration -- `SolanaInstruction`, `SolanaReadRequest` in Structs.sol -- Not fully implemented in current contracts - -**Future**: May expand to non-EVM destinations with adapted Socket - ---- - -## Design Rationale - -### Q30: Why don't you enforce maximum deadline limits? - -**Answer**: Application-level responsibility, not protocol concern. - -**Rationale**: - -- Different applications have different time requirements -- Some need hours, others need weeks or months -- Protocol shouldn't impose business logic constraints -- If app sets far-future deadline, it's their design choice - -**Application Responsibility**: - -- Apps should handle stale state appropriately -- Can implement their own deadline logic -- Can check conditions before execution - -**Example**: DeFi app might want 1-hour deadline, governance proposal might want 30-day deadline. - ---- - -### Q31: Why refund full msg.value on failed execution? - -**Answer**: Balance between simplicity and transmitter incentives. - -**Current Design**: - -- Failed execution → Full refund to refundAddress -- Transmitter loses gas cost for failed transaction - -**Rationale**: - -1. **Transmitters Should Simulate**: Off-chain simulate() function available -2. **External Reimbursement**: Transmitters compensated externally for failures -3. **Market Solution**: Bad plugs get blacklisted by transmitters -4. **Simplicity**: No complex partial refund logic needed - -**Griefing Vector**: Malicious plug could pass simulation but revert in production - -- **Mitigation**: Market-based reputation system -- **Impact**: Low - transmitters adapt behavior - -**Alternative Considered**: Keep socketFees even on failure - -- **Downside**: Legitimate failures (network issues, gas spikes) penalize users -- **Current**: More user-friendly, relies on transmitter rationality - ---- - -### Q32: Why allow reentrancy instead of using ReentrancyGuard? - -**Answer**: Gas optimization - unnecessary when CEI pattern is followed. - -**Gas Cost**: ReentrancyGuard adds ~2,500 gas per protected function - -**Why It's Safe**: - -```solidity -// Checks-Effects-Interactions pattern -function execute(...) { - // CHECKS - if (deadline < block.timestamp) revert; - if (executionStatus[id] == Executed) revert; - - // EFFECTS - executionStatus[id] = Executed; - payloadIdToDigest[id] = digest; - - // INTERACTIONS - target.tryCall(...); // Reentrancy here is safe -} -``` - -**Reentrancy Scenarios**: - -1. Same payloadId → Reverts (status already Executed) -2. Different payloadId → New execution, independent state -3. sendPayload() → Creates new payload, no state conflict - -**Verdict**: CEI pattern provides protection without gas overhead. - -**Note**: MessageSwitchboard.refund() DOES use ReentrancyGuard as extra safety for value transfers. - ---- - -### Q33: Why is increaseFeesForPayload() safe without additional checks? - -**Answer**: Multi-layer validation prevents abuse. - -**Validation Layers**: - -1. **Socket Layer**: `_verifyPlugSwitchboard(msg.sender)` - ensures plug is connected -2. **onlySocket Modifier**: Only Socket can call switchboard -3. **Plug Ownership**: Switchboard checks `payloadFees[id].plug == plug_` -4. **Off-Chain**: Watchers verify before applying fee updates - -**Attack Attempt**: - -```solidity -// Attacker tries to increase fees for someone else's payload -attacker.increaseFeesForPayload(victimPayloadId, feeData) - → Socket checks: attacker is connected ✓ - → Socket forwards to switchboard - → Switchboard checks: payloadFees[victimPayloadId].plug != attacker ✗ - → Reverts: UnauthorizedFeeIncrease -``` - -**Verdict**: Cannot increase fees for payloads you didn't create. - ---- - -## Open Questions for Auditors - -### Q34: Areas We'd Like Feedback On - -**1. Gas Limit Flexibility**: - -- No hardcoded maximum gas limit to support diverse chains -- Is this appropriate, or should we have a configurable max per chain? -- Could extremely high gasLimit values cause issues we haven't considered? - -**2. Switchboard Trust Model**: - -- Is the trust assumption on switchboards acceptable for production? -- Should we add on-chain reputation/bonding mechanisms? -- How should plugs evaluate switchboard trustworthiness? - -**3. Fee Economic Model**: - -- Native fee model: Is external transmitter reimbursement sufficient? -- Griefing attacks: Should protocol provide on-chain mitigation? -- Fee market: Will competition drive efficient delivery? - -**4. Counter Exhaustion**: - -- uint64 payloadCounter: ~18 quintillion payloads -- Should we add explicit handling for counter approaching max? -- Is revert-on-overflow the right approach, or should we allow rollover? - -**5. Upgrade Path**: - -- Contracts currently not upgradeable -- Is this appropriate for critical infrastructure? -- If security issue found, migration path is deploy-new-contracts -- Should we consider proxy pattern for critical contracts? - -**6. Cross-Chain State Synchronization**: - -- Protocol assumes eventual consistency -- No built-in ordering enforcement -- Is this appropriate for all use cases? -- Should we provide optional ordering mechanisms? - -**7. Edge Case Handling**: - -- Plug that always reverts: Acceptable? (Currently: yes, funds refunded) -- Excessive return data: Limited to maxCopyBytes (Currently: 2KB) -- Deadline precision: Uses block.timestamp (±15 seconds) -- Are these trade-offs appropriate? - ---- - -## Contact & Support - -**For Audit Questions**: - -- Open issue in repository with [AUDIT] tag -- Email: [audit-support@example.com] -- Discord: [#auditor-support channel] - -**For Technical Clarifications**: - -- Reference this FAQ first -- Check other documentation files -- Ask in audit communication channel - -**For Security Issues**: - -- DO NOT post publicly -- Email: [security@example.com] -- Use PGP key if available - ---- - -## Document Updates - -This FAQ is maintained during the audit process.

Payload executes on EVMX app gateway (via EVMX infrastructure) - -**Key Security**: Execution happens on EVMX chain, not via Socket.execute(). - ---- - -## Trust Assumptions - -1. **Switchboards are trusted by plugs** - - Anyone can register a switchboard - - Plugs must verify switchboard implementation before connecting - - Malicious switchboard can attest to invalid payloads - -2. **NetworkFeeCollector is trusted by Socket** - - Set by governance - - Called after successful execution for fee collection - - No reentrancy protection needed (trusted contract) - -3. **Target plugs are trusted by source plugs** - - Source plug configures destination plug addresses - - Cross-chain trust established at application level - - Invalid target only affects the plug that configured it - -4. **simulate() is off-chain only** - - Gated by OFF_CHAIN_CALLER (0xDEAD) - - Used for gas estimation by transmitters - -5. **Watchers act honestly** - - At least one honest watcher per payload - - Verify source chain state correctly - - Respect finality before attesting - -6. **Transmitters are rational** - - Should simulate before executing - - External reimbursement for failures - - Market-based reputation systems - ---- - -## Security Properties - -- **One-time execution**: Payloads execute at most once (enforced by execution status) -- **Digest immutability**: Once attested, digest cannot be changed -- **Source validation**: Switchboards verify source matches expected sibling/app gateway -- **Replay protection**: Nonces prevent signature replay attacks -- **Deadline enforcement**: Expired payloads cannot execute - ---- - -## Glossary - -- **Plug** - Application contracts that use Socket for cross-chain messaging. Plugs connect to switchboards and send/receive payloads. - -- **Switchboard** - Verification layer contracts that attest to payload authenticity. Different switchboard implementations provide different security/speed tradeoffs (e.g., MessageSwitchboard, EVMxSwitchboard). - -- **EVMX** - EVM execution layer that enables fast finality and cross-chain execution. EVMX has its own infrastructure for app gateways and watchers. - -- **Socket** - Main entry point contract on each chain. Handles payload execution (inbound) and submission (outbound). - -- **Payload** - Cross-chain message containing arbitrary data to execute on destination chain. Includes target address, calldata, value, gas limit, etc. - -- **Payload ID** - Unique identifier for each payload. Encodes source chain/switchboard, verification chain/switchboard, and counter. Used for routing and replay protection. - -- **Digest** - Hash of all execution parameters (payload, target, source, deadline, etc.). Watchers attest to digests, not raw payloads. - -- **Attestation** - Watcher signature on a payload digest. Required before payload can execute. Different switchboards require different attestation thresholds. - -- **Sibling Plug** - Counterpart plug on another chain. In MessageSwitchboard, source plug configures sibling plug address for source validation. - -- **App Gateway ID** - EVMX identifier for plugs. In EVMxSwitchboard, plugs configure their app gateway ID for source validation from EVMX. - -- **Watcher** - Off-chain agents that monitor source chains and attest to payload authenticity on destination chains. High trust requirement - at least one honest watcher per payload. - -- **Transmitter** - Off-chain agents that deliver payloads to destination chain and call `socket.execute()`. Low trust requirement - rational economic actors competing for fees. diff --git a/auditor-docs/README.md b/auditor-docs/README.md deleted file mode 100644 index 8b14882c..00000000 --- a/auditor-docs/README.md +++ /dev/null @@ -1,597 +0,0 @@ -# Socket Protocol - Auditor Documentation - -Welcome to the Socket Protocol auditor documentation package.

Socket (Entry Point) - -- Central contract on each chain -- Handles payload execution (inbound) and submission (outbound) -- Manages plug connections to switchboards -- Enforces execution rules (deadlines, gas limits, replay protection) - -### 2. Switchboards (Verification Layer) - -- Verify payload authenticity through attestations -- Multiple implementations: - - **FastSwitchboard**: EVMX-based fast finality - - **MessageSwitchboard**: Watcher-based with fee management -- Register with Socket and get unique IDs -- Maintain plug configurations and routing information - -### 3. Plugs (Application Layer) - -- User-deployed smart contracts -- Connect to Socket via specific switchboard -- Implement application logic for cross-chain interactions -- Call `socket.sendPayload()` to initiate cross-chain messages - -### 4. Watchers (Off-Chain) - -- Monitor source chain for payload requests -- Attest to payloads on destination chain -- Sign attestations for switchboard verification -- NOT in audit scope (off-chain infrastructure) - -### 5. Transmitters (Off-Chain) - -- Deliver payloads to destination chain -- Call `socket.execute()` with execution parameters -- Optionally sign for additional verification -- NOT in audit scope (off-chain infrastructure) - -## Trust Model & Assumptions - -### System Assumptions - -1. **Switchboards are trusted by Plugs/Apps** - - - Anyone can register as a switchboard - - Plugs only connect to switchboards they trust - - Users verify switchboard implementation before connecting - -2. **NetworkFeeCollector is trusted by Socket** - - - Socket calls networkFeeCollector after successful execution - - No reentrancy concerns as collector is trusted - -3. **Target Plugs are trusted by Source Plugs** - - - Source plugs specify and trust their sibling plugs on destination chains - - Invalid target plugs only affect the plug that configured them - -4. **simulate() function is for off-chain use only** - - - Gated by OFF_CHAIN_CALLER address (0xDEAD) - - Only used by off-chain services for gas estimation - - Not accessible on mainnet - -5. **Watchers act honestly** - - - At least one honest watcher per payload - - Watchers verify source chain state correctly - - Watchers respect finality before attesting - -6. **Transmitters are rational economic actors** - - Should simulate before sending transactions - - External reimbursement for failed deliveries - - May blacklist/whitelist plugs based on behavior - -## Key Design Decisions - -### Modular Switchboard Architecture - -**Decision**: Socket delegates verification to pluggable switchboard contracts rather than implementing verification directly. - -**Rationale**: - -- Different applications need different security/speed tradeoffs -- Allows upgrading verification mechanisms without changing core Socket -- Enables competition between verification methods - -### Payload ID Structure - -**Decision**: Payload IDs encode source, verification, and counter information in a single bytes32. - -**Format**: `[Source: 64 bits][Verification: 64 bits][Counter: 64 bits][Reserved: 64 bits]` - -**Rationale**: - -- Uniquely identifies payloads across all chains -- Enables routing validation (correct source → correct destination) -- Self-describing without additional lookups - -### Two-Phase Execution - -**Decision**: Separate payload creation (source chain) from execution (destination chain). - -**Rationale**: - -- Asynchronous cross-chain messaging -- Allows off-chain attestation layer -- Enables retry mechanisms and fee adjustments - -### Digest-Based Verification - -**Decision**: All execution parameters are hashed into a digest that switchboards attest to. - -**Rationale**: - -- Single attestation covers all parameters -- Prevents parameter manipulation after attestation -- Length-prefixed encoding prevents collision attacks - -### One-Time Execution - -**Decision**: Payloads can only be executed once, even if they fail. - -**Rationale**: - -- Simplicity: No complex retry logic needed -- Determinism: Clear finality for each payload -- Security: Prevents replay attacks and complex re-execution scenarios -- Application Layer: Apps can send new payloads if needed - -### No Ordering Enforcement - -**Decision**: Payloads can execute in any order on destination chain. - -**Rationale**: - -- Cross-chain messaging is inherently asynchronous -- Different chain finality times make ordering impractical -- Transmitter competition for fees -- Application layer can handle ordering if needed -
