## 📋 Next Steps for Deployment

### Local Development

1. **Configure environment variables:**
   ```bash
   # Edit .env file with your actual values
   nano .env
   ```

2. **Validate configuration:**
   ```bash
   pnpm run validate
   ```

3. **Start development server:**
   ```bash
   pnpm run dev
   ```

### Production Deployment (VMIDs 2400-2402)

Follow the detailed steps in `DEPLOYMENT.md`:

1. **Deploy supporting services:**
   - Redis VMID
   - Web3Signer VMID
   - Vault VMID

2. **Deploy translator on each VMID (2400, 2401, 2402):**
   - Install Node.js 20 LTS
   - Copy application files
   - Install dependencies: `pnpm install --prod`
   - Build: `pnpm run build`
   - Configure `.env` file
   - Create systemd service
   - Start service

3. **Update edge routing:**
   - Update Cloudflare Tunnel or Nginx configuration
   - Route external :8545/:8546 → translator :9545/:9546

4. **Validation:**
   - Test WebSocket subscriptions
   - Test transaction sending
   - Test nonce management
   - Test failover

## 🔧 Available Scripts

- `pnpm run build` - Build TypeScript to JavaScript
- `pnpm start` - Run production server
- `pnpm run dev` - Run development server (with auto-reload)
- `pnpm run validate` - Validate .env configuration
- `pnpm run setup` - Run setup script (installs deps, creates .env, builds)

## 📝 Important Notes

1. **Environment Variables**: The `.env` file contains placeholder values (XXX). You must update these with actual IPs/credentials before running.

2. **Vault Configuration**: Vault is optional - you can use environment variables instead. If using Vault:
   - Get AppRole credentials from Vault admin
   - Store in `.env` file
   - Ensure translator has network access to Vault

3. **Redis**: Required for nonce management. Ensure Redis is accessible from translator VMIDs.

4. **Web3Signer**: Required for transaction signing. Ensure Web3Signer is configured with the wallet keys and accessible from translator VMIDs.

5. **Network Access**: Ensure firewall rules allow:
   - Translator → Besu (127.0.0.1:8545/8546)
   - Translator → Redis (192.168.11.110:6379) - VMID 106
   - Translator → Web3Signer (192.168.11.111:9000) - VMID 107
   - Translator → Vault (192.168.11.112:8200) - VMID 108

## 🚀 Quick Start (Development)

```bash
# 1. Configure .env
cp env.template .env
nano .env  # Edit with your values

# 2. Validate configuration
pnpm run validate

# 3. Build (if not already built)
pnpm run build

# 4. Start development server
pnpm run dev
```
