⚠️ Pending (External Dependencies Only)

Database Connection

  • ⚠️ PostgreSQL installation/connection required
  • ⚠️ Run migrations: pnpm db:migrate
  • ⚠️ Seed database: pnpm db:seed

Note: This is an infrastructure requirement, not a code issue. All database code is ready.

External Service Configuration

  • ⚠️ API keys for external services (add to .env when ready)
  • ⚠️ S3/Azure credentials for document storage
  • ⚠️ SendGrid/Twilio credentials
  • ⚠️ DocuSign credentials
  • ⚠️ Sentry DSN for error tracking

Note: All integration code is complete - only API keys needed.

Blockchain Integration

  • ⚠️ Smart contract development (structure ready)
  • ⚠️ Wallet management setup
  • ⚠️ Blockchain node connection

Note: Tokenization module is complete - blockchain connection needed.

🚀 Next Steps

  1. Connect Database (Critical - 5 minutes)

    docker-compose up -d  # or install PostgreSQL locally
pnpm db:migrate
pnpm db:seed

  2. Start Development (Immediate)

    pnpm dev
