Changelog
| Version | Date | Summary |
|---|---|---|
| 1.0.0 | 2026-03-25 | Initial release. Conforms to FPSF-SS-001 v1.0.0. Defines the wallet-gateway WebSocket interface: connection model, per-message authentication, all request-response operations, subscription model, asynchronous submission status lifecycle, error handling, and conformance requirements. Reflects the updated fee model (GET_FEES returns operatorFee, acquiringFee, totalWithFees separately). Reflects the separation of orderReference and acquirerId into independent bytes16 fields in PayWithPermitParams. |
