USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

说明与用途

在Base上使用最小化的托管模式，AI代理仅在通过预映像哈希证明完成任务后才能收到USDC，并提供超时退款机制。

问题

Ensuring payment for autonomous AI agents only after they complete a verifiable task, without relying on human arbitrators.

结果

The pattern enables trustless, atomic payment for AI agents, reducing reliance on human arbitrators and minimizing gas costs.

工作流

• 1. Payer defines task spec and computes expected hash off‑chain.
• 2. Payer deploys SimpleHashEscrow with the hash, beneficiary, and timeout.
• 3. Payer funds the escrow via ERC20 transferFrom.
• 4. Agent executes the task, produces result, and computes its hash.
• 5. Agent calls escrow.release(result) on-chain; if hash matches, USDC is transferred to beneficiary.
• 6. If result mismatches or agent fails, transaction reverts and payer can later call refund() after deadline.

证据

The escrow holds funds until a pre‑image hashes to expectedHash.

来源

If the agent fails or returns a mismatched result, the transaction reverts; the payer can later call refund() after the deadline.
