Package Manager

✅ pnpm is now the default package manager:

• ✅ Workspace configuration (pnpm-workspace.yaml)
• ✅ All documentation updated to use pnpm
• ✅ All scripts updated to use pnpm
• ✅ Dockerfiles updated to use pnpm
• ✅ Makefiles updated to use pnpm

Next Steps

1. Database Integration: Replace in-memory stores with database (PostgreSQL/MongoDB)
2. Event Indexing: Implement blockchain event indexing for off-chain state
3. Enhanced Error Handling: Map Solidity reason codes to HTTP status codes
4. Rate Limiting: Implement rate limiting middleware
5. Request Logging: Add comprehensive request/response logging
6. Metrics & Observability: Add OpenTelemetry integration
7. Testing: Expand integration and unit tests
8. Production Deployment: Configure for production environments

Notes

• In-memory stores are used for development/testing. Production should use persistent databases.
• Blockchain client requires contract addresses via environment variables.
• Some services have placeholder implementations that should be enhanced with actual business logic.
• GraphQL resolvers delegate to REST service layer for consistency.
