Improvements

Sweep Logic Enhancements

  • Major improvements to sweep logic

  • Fixed sweep task conflicts
  • Fixed precision when updating balances
  • Implemented sweep batches in chunks
  • Improved sweep job logic

Error Handling & Reliability

  • Enhanced error handling (#315)
  • Refactored MPC signing event for better error handling
  • Increased MPC signing withdrawal timeout
  • Enhanced robust automation logic
  • Fixed stack overflow issue
  • Improved payment service

Configuration & Deployment

  • Used distroless to build Docker image for API (improved security)
  • Better logging setup
  • Updated Redis configuration
  • Support building multiple architectures
  • Refactored Docker Compose setup for APEX services
  • Added production scripts
  • Updated configuration to allow logging

API & Endpoints

  • Added rescan API to rescan missing blocks
  • Added RPC health check script
  • Updated Consul version and configuration
  • Only add HTTP auth if both username and password are defined
  • Return 404 instead of 500 for webhook validation
  • Fixed #288: renamed reject to cancel for cancel API for withdrawal (#299)

Rate Limiting

  • Made rate limit configurable

Bug Fixes

  • Fixed MPC transaction broadcast for TRON
  • Fixed get Webacy configuration
  • Fixed add asset TRX assets not shown
  • Replaced dummy addresses with proper implementation
  • Removed root user migration for production
  • Fixed various typos and minor issues

Developer & Internal Changes

  • Cleaned up codebase
  • Reverted HA changes on rescanner and scheduler (rescanner supports distributed mode, scheduler does not support multiple instances)
  • Code refactoring for leader logic
  • Moved start rescanner logic to initialize
  • Updated documentation
  • Removed hardcoded values
  • Discarded draft code
  • Reverted testnet seed assets
  • Updated Makefile
  • Refactored create webhook verification key
  • Refactored add asset to wallet logic
  • Updated wallet asset management for Hyper wallet
  • Added batch logic for statistic indexer

Deployment Notes

  • AWS KMS Integration: If using AWS KMS for key management, ensure AWS credentials and KMS configuration are properly set
  • Secret Store: Update configuration to use secret store instead of direct config files for sensitive data
  • Queue Migration: NATS JetStream configuration required for queue-based messaging (pubsub is now legacy)
  • Docker Images: New distroless-based Docker images provide improved security
  • Multi-Architecture: Docker images now support multiple architectures (amd64, arm64)
  • HA Deployment: Use provided HA sample configuration for high availability setups
  • TLS Configuration: Ensure TLS certificates are configured if using encrypted connections
  • System Admin: First deployment requires creating a system admin user for network/asset management
