USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

说明与用途

USDC Escrow 合约在 Base 上使 AI 代理仅在提交加密证明后才收到付款，消除了对中心化中介的需求。

问题

Developers building autonomous AI agents need a way to receive payment for verifiable work without relying on a centralized intermediary.

结果

The escrow contract enables trustless, non‑custodial payment for AI agents with minimal gas costs (~$0.0005) and low payment amounts (~$0.01).

工作流

• 1. Client approves USDC transfer to escrow contract via usdc.approve(address(escrow), amount)
• 2. Client calls createJob(jobId, agent, amount, durationSeconds) to lock funds for a specific job ID
• 3. Agent stores result off-chain (e.g., IPFS) and computes proofHash = keccak256(ipfsCid)
• 4. Agent signs jobId off-chain; client verifies signature before proceeding
• 5. Agent calls submitProof(jobId, proofHash) to submit proof
• 6. Escrow contract releases USDC to agent if proof submitted before deadline
• 7. If no proof before deadline, client calls refund(jobId) to reclaim funds

证据

A trustless escrow flips the model: the payer locks funds in a smart contract that can only release them when the agent presents cryptographic proof of completion.

The contract is deliberately minimal to avoid upgradeability risks and to keep audit surface small.
