💊 nad.fun bundler

nad.fun bundler is a Pump.fun-inspired bundler that runs entirely on Monad’s EVM-compatible. It lets anyone launch viral tokens, route buys and sells through a bonding curve, and migrate mature pools onto Uniswap liquidity—without leaving the Solidity/Hardhat toolchain.

🔍 Repo tour

Path	Purpose
contracts/Core.sol	Main router for buys, sells, slippage-protected orders, and fee routing.
contracts/Bundler.sol	Deploys bonding-curve instances and orchestrates launch/migration flows.
contracts/utils/*	Math helpers, safe transfer libs, and native-asset handling.
contracts/interfaces/*	Minimal ABI surface for frontends, scripts, and auditors.
scripts/createAndBuy.ts	Example Hardhat script that deploys, buys, and prints receipts.

✨ Feature set

• One-click launches – deploy a bonding curve, seed reserves, and mint supply in one transaction.
• Bundled buys – ETH deposit, fee capture, reserve math, and token mint happen atomically.
• Sell variations – standard sells, permit-based sells, and slippage-protected variants.
• Fee vaulting – protocol fees stream to a vault contract for later withdrawal.
• Liquidity migration hooks – once thresholds are met, liquidity can hop to Uniswap pools.
• Safety rails – transfer helpers, allowance checks, bonding-curve math guards, and deadlines.

⚙️ Quick start

1. Install

   npm install

2. Configure

   cp .env.example .env

3. Compile

   npx hardhat compile
   # or
   npm run build

4. Test

   npx hardhat test
   # or
   npm run test

5. Demo script

   ts-node scripts/createAndBuy.ts
   ## or
   npm run createAndBuy

🔄 Runtime flow

1. Launch: Bundler deploys curve + token contracts, initializes virtual reserves, and records config.
2. Buy: Core calculates amountOut via BondingCurveLibrary, mints tokens, forwards ETH, and sweeps protocol fees.
3. Sell: Users transfer tokens into the curve; Core unwraps WNative, sends ETH out, and routes fees to the vault.
4. Protect: protectBuy and protectSell enforce min/max outputs to guard against slippage.
5. Migrate: Once the curve hits its liquidity threshold, prepared hooks move liquidity to Uniswap (future expansion).

🌐 Networks

hardhat.config.ts ships with:

• monadMainnet – https://rpc.monad.xyz (chain ID 143)
• monadTestnet – https://testnet-rpc.monad.xyz (chain ID 10143)

Add your PRIVATE_KEY to the .env file so scripts and deployments can sign transactions.

🧪 Tests & artifacts

• test/Bundler.test.ts exercises the new Bundler contract end-to-end (curve creation, buys, sells, fees). A fresh Hardhat run is documented in screenshot.png.
• Artifacts for each interface/contract can be found under artifacts/.
