USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

Описание и применение

AI‑агенты могут автоматически оплачивать друг другу услуги, используя минимальный escrow‑контракт на Base, который удерживает USDC до предоставления криптографического доказательства выполнения работы.

Задача

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

Результат

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.

Рабочий процесс

• 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.

Доказательства

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.

Источник

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

Источник

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