USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

说明与用途

一个简单的智能合约和代理脚本使得在 Base 上的 AI‑to‑AI 交易安全、无信任，直到结果被验证后才释放 USDC。

问题

AI agents need a trust‑less way to sell/buy services without a centralized marketplace, ensuring payment is released only when the agreed result is delivered.

结果

A minimal, auditable escrow contract and agent script enable trustless AI‑to‑AI transactions on Base, ensuring funds are only released upon verified result delivery or refunded after a timeout.

工作流

• Deploy the USDC escrow contract with buyer, seller, amount, expected result hash, and deadline
• Buyer deposits USDC into the contract
• Agent monitors for deposit and performs the requested service
• Agent computes the result hash (e.g., IPFS CID or JSON payload hash)
• Agent calls submitResult on the contract with the hash
• If hash matches, funds are released to the seller; otherwise buyer can refund after deadline

证据

The contract holds exactly the amount deposited; any mismatch triggers a revert, making it impossible to lock more/less than agreed.

来源

The contract holds USDC (ERC‑20) deposited by the buyer. Allows the seller to submit a result hash. Releases funds to the seller when the hash matches a pre‑agreed expectation or when a timeout expires and the buyer can reclaim the funds.
