- Add signing-config API endpoints (POST/PUT/DELETE/GET) for configuring
which parties should participate in signing operations
- Add SigningParties field to Account entity with database migration
- Modify CreateSigningSession to use configured parties if set,
otherwise use all active parties (backward compatible)
- Add delegate party signing support: user provides encrypted share
at sign time for delegate party to use
- Update protobuf definitions for DelegateUserShare in session events
- Add ShareTypeDelegate to support hybrid custody model
API endpoints:
- POST /accounts/:id/signing-config - Set signing parties (first time)
- PUT /accounts/:id/signing-config - Update signing parties
- DELETE /accounts/:id/signing-config - Clear config (use all parties)
- GET /accounts/:id/signing-config - Get current configuration

- Remove Address field from PartyEndpoint (parties connect to router themselves)
- Update K8s Discovery to only manage PartyID and Role labels
- Add Party registration and SessionEvent protobuf definitions
- Implement PartyRegistry and SessionEventBroadcaster domain logic
- Add RegisterParty and SubscribeSessionEvents gRPC handlers
- Prepare infrastructure for party-driven MPC coordination
This is the first phase of migrating from coordinator-driven to party-driven
architecture following international MPC system design patterns.
- Add retry mechanism for PostgreSQL connections (10 retries, 2s base delay)
- Add retry mechanism for RabbitMQ connections (10 retries, 2s base delay)
- Add retry mechanism for Redis connections (10 retries, 2s base delay)
- Use exponential backoff: delay increases with each retry attempt
- Log detailed retry information (attempt number, max retries, errors)
- Redis continues without cache if all retries fail (non-critical)
- Database and RabbitMQ return error after all retries (critical)
This resolves startup failures when dependent services are slow to initialize,
particularly RabbitMQ which may pass health checks but not be fully ready.
Major changes:
- Add TSS core library (pkg/tss) with keygen and signing protocols
- Implement gRPC clients for Server Party service
- Add MPC session endpoints to Account service
- Deploy 3 Server Party instances in docker-compose
- Add MarkPartyReady and StartSession to proto definitions
- Complete integration tests for 2-of-3, 3-of-5, 4-of-7 thresholds
- Add comprehensive documentation (architecture, API, testing, deployment)
Test results:
- 2-of-3: PASSED (keygen 93s, signing 80s)
- 3-of-5: PASSED (keygen 198s, signing 120s)
- 4-of-7: PASSED (keygen 221s, signing 150s)
