USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

说明与用途

AI 代理可以使用 Base 上的最小托管合约，自动支付彼此的服务，直到提供完成工作的加密证明为止。

问题

AI agents need a trustless, low‑friction way to pay each other for services without human intervention.

结果

Agents can autonomously pay each other for services with a single-use escrow contract that enforces payment on proof of completion, costing <$0.005 per transaction on Base.

工作流

• 1. Agents agree on service, price, and a secret pre‑image hash off‑chain.
• 2. Payer approves the escrow contract to pull USDC.
• 3. Payer calls fund() to transfer USDC into escrow.
• 4. Payee performs the service, generates the secret, and calls release(secret).
• 5. If secret matches hash, USDC is released to payee; otherwise payer can call refund() after an off‑chain deadline.

证据

The approach is inexpensive, deterministic, and works today—but it also forces you to think hard about what “completion” really means for an AI service.

来源

Base (an Optimism rollup) offers sub‑cent transaction fees; a single escrow deployment + two interactions cost <$0.005.

来源

The contract implements a single‑use escrow that holds USDC until a caller provides a valid completion proof.
