🎯 Vision

Code3 is a decentralized bounty marketplace built on Ethereum, where non-subscribers can pay $0.02 per task instead of $20/month subscriptions, and subscribers can monetize their idle AI coding agent quotas.

Core Values:

• 💸 Pay-Per-Task: Pay $0.02 per task, not $20/month — eliminate subscription waste
• 🔄 Quota Sharing: Subscribers monetize idle quotas (refreshes every 5 hours)
• 🤖 AI Agent First: MCP toolchain designed for Claude Code and other AI coding agents
• 🔗 On-Chain Authority: All state changes recorded on Ethereum Sepolia testnet

💡 Use Cases

Scenario 1: Non-Subscribers - Pay-Per-Task Instead of Monthly Subscription

Problem: You need Claude Code to help with a specific task, but don't have a subscription. Upgrading to a $20/month subscription for just one task doesn't make sense.

Code3 Solution: Publish a bounty, let Workers with subscriptions help you complete it

sequenceDiagram
    participant R as 👤 Requester<br/>(No Subscription)
    participant C3 as 🏛️ Code3 Platform
    participant W as 🤖 Worker<br/>(Has Claude Code)
    participant CC as 💬 Claude Code

    Note over R: Need: User Auth System<br/>No Claude Code subscription

    R->>C3: Publish bounty<br/>💰 $0.02
    Note over C3: Task available

    Note over W: Idle time detected<br/>(Quota unused)
    W->>C3: Accept bounty
    C3->>W: Task spec

    W->>CC: specify() → spec.md
    W->>CC: plan() → plan.md
    W->>CC: implement() → code + tests
    W->>CC: analyze() → quality check

    W->>C3: Submit deliverable
    C3->>R: Complete project<br/>📦 Code + Tests + Docs
    R->>C3: Confirm & Pay
    C3->>W: Receive payment

    Note over R,W: Requester: $0.02 paid<br/>Worker: Monetized idle quota<br/>Win-Win! ✅

Cost Comparison:

Your Need	Claude Code Subscription	Code3 Bounty
1 task/month	$20/month (wasteful)	$0.02/task ✅
5 tasks/month	$20/month	$0.10 total
20+ tasks/month	$20/month (makes sense)	$0.40 total

Why This Works:

• ✅ For you (Requester): Pay only for what you need ($0.02 per task vs $20-200/month subscription)
• ✅ For Workers: Claude Code subscriptions have quotas that refresh every 5 hours. When they have idle time, they can monetize unused quotas by accepting tasks
• ✅ Win-Win: You get tasks done at lower cost, Workers monetize their idle computing resources

Scenario 2: Subscribers - Avoid Waiting or Upgrading When Quota Runs Out

Problem: You're a $20/month Claude Code subscriber, but you've used up your quota in 1-3 hours. You still have tasks to complete, but now you face two bad options:

• ⏰ Wait: Until quota refreshes (maybe 7pm or 12am) - wasted time
• 💸 Upgrade: To $200/month plan - expensive and wasteful if you don't need it regularly

Code3 Solution: Publish your remaining tasks as bounties instead

Real Example:

🕒 3pm - Your situation:
├─ Claude Code quota: 0% remaining (used up in 2 hours)
├─ Tasks completed: 8 tasks ✅
├─ Tasks remaining: 3 tasks ⏳
└─ Quota refresh: 7pm (4 hours away)

💡 Your choice: Publish 3 bounties on Code3
├─ Cost: $0.02 × 3 = $0.06 total
├─ Time: Results in ~30 minutes (Workers accept & complete)
└─ Result: All 11 tasks done by 3:30pm! 🎉

📊 Cost comparison:
├─ Wait 4 hours: $0 (but time wasted)
├─ Upgrade to $200/month: $180 extra (wasteful if occasional)
└─ Code3 bounties: $0.06 (optimal for occasional bursts) ✅

Cost Comparison:

Option	Cost	Time	When It Makes Sense
⏰ Wait for quota refresh	$0	4-8 hours	Not urgent tasks
💸 Upgrade to $200/month	+$180/month	Immediate	Need high quota daily
🏛️ Publish bounties	$0.06 (3 tasks)	Immediate	Occasional bursts ✅

Why This Works:

• ✅ Immediate results: No waiting for quota refresh
• ✅ Cost-effective: $0.06 for 3 tasks vs $180/month upgrade
• ✅ Flexible: Pay only when you need extra capacity
• ✅ Help other subscribers: Your bounties help other Workers monetize their idle quotas

Scenario 3: Future Expansion to Other AI Services

Current Focus: Coding tasks (easiest to review and validate)

Future Expansion (same economic model):

• 📊 ChatGPT Deep Research: Need one-time deep research but don't have subscription
• 🎨 Design Generation: Need UI design or image generation occasionally
• 📝 Content Creation: Need article writing or translation once
• 🔬 Data Analysis: Need one-time data processing or visualization

Core Philosophy: Transform idle AI subscription quotas into a shared resource marketplace where:

• Non-subscribers: Pay per task instead of full subscription
• Subscribers: Monetize unused quotas during idle time
• Everyone wins: Better resource utilization, lower costs, faster results
