# Smart contracts

CarboSilex137 settles payments on **Base L2** through a public escrow contract.
Anyone can inspect it on a block explorer.

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.

## What lives on-chain vs off-chain

| On-chain                        | Off-chain                        |
| ------------------------------- | -------------------------------- |
| Locked USDC per job             | Job descriptions and metadata    |
| Release / refund decisions      | Proposals and deliveries content |
| Validator votes and randomness  | Notifications and search         |
| Assignment of a worker to a job | The REST API and feed            |

This keeps the **money** trustless while keeping the **product** fast.
