Summary

Completion Status

  • Frontend: 7/7 tickets (100%) ✅
  • Backend APIs (Mock): 3/11 tickets (27%) - Mock endpoints created
  • Smart Contracts: 0/4 tickets (0%) - Requires infrastructure setup
  • Integration: 0/2 tickets (0%) - Requires orchestrator service
  • Testing: 0/3 tickets (0%) - Can be started for frontend

Total Progress

  • Completed: 10/28 tickets (36%)
  • Pending: 18/28 tickets (64%)

Next Steps

Immediate (Can be done now)

  1. TEST-001: Implement E2E tests for builder flow
  2. TEST-002: Implement E2E tests for failure scenarios
  3. Enhance existing components based on user feedback

Requires Infrastructure Setup

  1. Set up Orchestrator Service: Create separate backend service for plan management, execution coordination
  2. Set up Smart Contracts: Initialize Hardhat/Foundry project, deploy contracts
  3. Set up Database: Database for plan storage, audit logs
  4. Set up External Integrations: Bank APIs, KYC/AML providers

Architecture Decisions Needed

  1. Orchestrator Service: Choose framework (Express, FastAPI, NestJS)
  2. Database: Choose database (PostgreSQL, MongoDB)
  3. Message Queue: For async execution coordination (RabbitMQ, Redis)
  4. Deployment: Choose deployment platform (Docker, Kubernetes, Cloud)
