How I Built an Autonomous AI Agent That Earns USDC While I Sleep

说明与用途

一个自治代理自动处理Base L2上的USDC支付，执行推理并转账，降低人工运维。

问题

Running a paid AI service on Base L2 requires constant ops: monitoring usage, topping up balances, handling failed transactions, and keeping the service online.

结果

The autonomous agent automatically processes payments, runs inference, and forwards USDC, enabling a self‑sustaining AI service with minimal manual intervention.

工作流

• Deploy a minimal ERC‑20 escrow contract on Base to hold USDC and emit PaymentReceived events.
• Deploy a stateless FastAPI agent that listens for PaymentReceived via WebSocket or polling.
• Validate the payer’s signature to prevent replay attacks.
• Execute the core workload (model inference, data transform, etc.).
• Call escrow.release to pull earned USDC into the agent’s wallet.
• Forward USDC to a controlled wallet (EOA, multisig, or contract).

证据

Receives payment‑triggered requests via a smart‑contract escrow.
