How it works

Every order follows the same five-step lifecycle. Payments are USDC transfer authorizations on base_sepolia; the buyer never pays gas.

  1. 01
    Quote

    Pick a tool and input; the gateway returns the fixed price and an expiration.

  2. 02
    Pay

    Connect your wallet (MetaMask or any EIP-1193 wallet) and sign a USDC transfer authorization for exactly the quoted amount — no broadcast, no gas.

  3. 03
    Verify & settle

    The facilitator verifies the signature and settles the transfer on-chain.

  4. 04
    Fulfill

    The order runs the approved route, with automatic failover between approved routes.

  5. 05
    Deliver

    The artifact is stored in R2 and streamed to you with a SHA-256 integrity check.
