USDC Escrow for AI Agents: How Trustless Freelancing Actually Works

Description and use

A minimal USDC escrow contract enables autonomous agents to securely buy and sell micro‑services without central marketplaces, automatically releasing funds when work is cryptographically proven.

Problem

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.

Outcome

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

Workflow

• 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.

Evidence

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

Source

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