## 🔧 Integration Required

The following components have skeleton implementations and require external API integrations:

1. **DEX Aggregators**: Add API keys and implement actual API calls
   - 1inch API
   - 0x API
   - Paraswap API

2. **KYC Providers**: Add credentials and implement verification flows
   - Jumio
   - Onfido

3. **Payment Rails**: Integrate providers
   - On-ramp: MoonPay, Ramp
   - Off-ramp providers
   - ACH/Wire integration

4. **WalletConnect**: Add WalletConnect v2 SDK
   - Requires WalletConnect project ID

5. **Soul Machines**: Add SDK for VTM
   - Requires API credentials

6. **External Services**:
   - Redis (for rate limiting and caching)
   - Kafka/RabbitMQ (for message queuing)
   - KMS/HSM (for key management)

## 📝 Next Steps

1. **Configure Environment**
   - Copy `.env.example` to `.env`
   - Fill in all required values

2. **Set Up Infrastructure**
   ```bash
   docker-compose -f deployment/docker-compose.yml up -d
   ```

3. **Run Migrations**
   ```bash
   cd backend && go run database/migrations/migrate.go
   ```

4. **Start Services**
   ```bash
   ./scripts/run-dev.sh
   ```

5. **Integrate External APIs**
   - Add API keys to configuration
   - Complete skeleton implementations

6. **Testing**
   - Add comprehensive test coverage
   - Set up integration tests

7. **Deployment**
   - Configure Kubernetes
   - Set up CI/CD pipelines
   - Configure monitoring and alerting
