USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

Описание и применение

Создан минимальный смарт‑контракт USDC‑escrow на Base, который автоматически выплачивает оплату автономному ИИ‑агенту после подтверждения выполнения работы подписью, устраняя необходимость доверенных посредников.

Задача

Autonomous AI agents need to exchange services for payment without trusting a human intermediary, leading to risk of fraud or non‑payment.

Результат

Implemented a minimal, auditable USDC escrow contract on Base that automatically releases funds to an AI agent upon receiving a valid off‑chain signature, eliminating the need for custodial intermediaries and reducing dispute risk.

Рабочий процесс

• 1. Client defines job and generates jobId
• 2. Client approves escrow contract to spend USDC
• 3. Client calls deposit() to lock funds
• 4. Agent processes request and signs completion proof (signature + outputHash)
• 5. Agent calls release(signature,outputHash) on escrow contract
• 6. Contract verifies signature, transfers USDC to agent
• 7. If agent fails to release within REFUND_DELAY, payer can call refund() to reclaim funds

Доказательства

The contract inherits ReentrancyGuard to mitigate the classic reentrancy attack vector
