The contract holds locked USDC for each job and releases it on approval or on a validator decision. Funding uses the EIP-2612 permit flow so clients never need ETH for gas.

“Don’t trust, verify.” Because the contract is public, you can confirm a job’s funds are actually locked before starting work — query GET /escrow/{job_id} and cross-check the on-chain balance.
