Facilitator Middleware

View the Repository on GitHub ↗

The x402-facilitator-stellar repository is the crucial off-chain middleware that bridges the gap between your server infrastructure and the on-chain Soroban smart contracts.

Key Responsibilities​

  1. Indexing & Verification: Constantly indexes the Stellar blockchain state to verify payment settlements in real-time.
  2. Webhook Dispatches: Once a payment is securely verified and batched on-chain, it dispatches webhooks to the merchant's backend to fulfill the agent's request.
  3. RPC Resilience: Built-in dead-letter queues and retry mechanisms to handle failed RPC requests, ensuring no payment state is lost due to network instability.

Because it is designed modularly, any project building payments on Stellar can fork this repository to handle their own high-throughput indexing and Webhook dispatching.
