Your client signs an EIP-712 message; your server calls this facilitator to verify the signature, and the facilitator settles the token transfer on-chain via [Fireblocks](https://www.fireblocks.com/).\n\n## Documentation\n\nThe full documentation lives on the Fireblocks developer site:\n\n- [Overview](https://developers.fireblocks.com/docs/x402-facilitator-overview) — what x402 is, what this facilitator does, and how it fits into a merchant stack.\n- [Integration](https://developers.fireblocks.com/docs/x402-facilitator-integration) — quick start, merchant-server integration, config file, payment processing API.\n- [Operations](https://developers.fireblocks.com/docs/x402-facilitator-operations) — management API, CLI reference, payment instruction integrity, production deployment, multi-merchant setup.\n\nFor an architectural deep-dive (auth model, source layout, transfer mechanisms, payment lifecycle, reconciliation), see [`ARCHITECTURE.md`](./ARCHITECTURE.md).\n\n\u003e **Open-source or hosted?** This repository is the open-source facilitator that you run yourself. Fireblocks also offers a fully managed, production-grade hosted x402 Facilitator. [Talk to us about early access](https://www.fireblocks.com/#request-demo).\n\n## License\n\nApache License 2.0 — see [LICENSE](./LICENSE).\n\n## Disclaimer\n\nThis software handles on-chain value transfer. Before integrating, please read the full [DISCLAIMER](./DISCLAIMER.md) — it covers irreversibility of on-chain transfers, the absence of a third-party security audit, third-party contract risk (Permit2, MetaMask Delegation Framework, ERC-20 token contracts including USDC / USDT blacklisting mechanics), the non-advisory nature of this code, jurisdictional and data-protection considerations (GDPR / UK GDPR), the Fireblocks trademark, the absence of any fiduciary or custodial relationship, and the independence of the x402 protocol specification.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffireblocks%2Fx402-facilitator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffireblocks%2Fx402-facilitator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffireblocks%2Fx402-facilitator/lists"}
