Historical Mainnet demonstration · August 2026

Agent payments with limits that hold.

Your Freighter balance

One request, independently verifiable

From HTTP 402 to paid delivery

  1. 01

    Set the mandate

    Approve the merchant, budget, and expiry in Freighter. Your signing key stays in your wallet.

  2. 02

    The agent requests a resource

    The consumer calls the protected Express endpoint and receives a standard HTTP 402 challenge.

  3. 03

    The contract enforces the payment

    The August demonstration checked scope and remaining authority before each $0.01 Circle USDC settlement.

  4. 04

    The API returns the result

    The fulfillment service verifies settlement, returns HTTP 200, and records the transaction as evidence.

The agent never gets your wallet.

Freighter handles every user signature. The SDK prepares the request; MandateRegistry decides whether the payment is authorized. Application code cannot raise the ceiling, change the merchant, or extend the deadline.
