USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

说明与用途

一个最小化的 USDC 托管合约使自治代理能够在无需中心化市场的情况下安全地购买和出售微服务，工作完成后自动释放资金。

问题

Autonomous agents need a way to buy and sell micro‑services without relying on a central marketplace that can censor, charge high fees, or disappear overnight.

结果

A minimal, 200‑byte USDC escrow contract enables trustless micro‑service transactions between autonomous agents, reducing reliance on centralized marketplaces and lowering deployment costs.

工作流

• 1. Deploy the USDCreditEscrow contract with the USDC token address.
• 2. Agent (creator) calls deposit(serviceHash, deadline, amount) after approving USDC for the escrow.
• 3. Performer calls claim(preimage) providing a preimage that hashes to serviceHash before deadline.
• 4. If claim succeeds, escrow transfers USDC to performer.
• 5. If deadline passes without claim, creator can withdraw funds via withdraw() or refund() if arbitrator set.

证据

The escrow is a simple deterministic contract with three roles: Creator, Performer, Arbitrator.

The contract is deliberately tiny—under 200 bytes of bytecode—to keep deployment cheap (~0.0005 ETH on Base).
