- **Multi-DEX Price Queries**: <100ms for 4 DEXs
- **Slippage Analysis**: <0.5ms per calculation
- **Memory Footprint**: <1MB additional overhead
- **Gas Price Updates**: Every 30 seconds
- **Price Feed Updates**: Every 15 seconds

**Key Metrics to Monitor:**
- Opportunity detection rate
- Profit calculation accuracy
- System response time
- Memory usage
- Network connectivity

### 🛡️ Security Considerations

**✅ Security Measures Implemented:**
- [x] No hardcoded secrets or API keys
- [x] Proper input validation throughout
- [x] Thread-safe concurrent operations
- [x] Comprehensive error handling
- [x] Secure logging (no sensitive data exposure)

**Security Checklist:**
- [ ] Verify encryption key is properly secured
- [ ] Confirm RPC endpoints are trusted
- [ ] Validate network security settings
- [ ] Review logging output for sensitive data
- [ ] Test error handling under adverse conditions

### 🔍 Monitoring and Observability

**Enhanced Logging Features:**
- Detailed arbitrage opportunity analysis
- Real-time profit calculations with breakdown
- Slippage risk assessments
- Multi-DEX price comparison results
- Gas cost estimations with MEV adjustments

**Log Levels:**
- `DEBUG`: Detailed profit calculations and slippage analysis
- `INFO`: Opportunity discoveries and system status
- `WARN`: Risk warnings and validation failures
- `ERROR`: System errors and connectivity issues

**Key Metrics to Track:**
- Total opportunities analyzed
- Executable opportunities percentage
- Average profit margins
- Slippage risk distribution
- Gas cost accuracy
- Multi-DEX price spread detection

### 🧪 Testing Recommendations

**Pre-Production Testing:**
```bash
# 1. Build verification
go build ./cmd/mev-bot

# 2. Short runtime test (5 seconds)
timeout 5 ./mev-bot start

# 3. Check logs for enhanced features
grep -E "(arbitrage|profit|slippage)" logs/mev_bot.log | tail -10

# 4. Memory usage monitoring
ps aux | grep mev-bot
```

**Production Monitoring:**
- Monitor opportunity detection rates
- Track profit calculation accuracy
- Watch for slippage risk warnings
- Verify gas price updates
- Check multi-DEX price feed health

### 🎯 Success Criteria

**System is ready for production if:**
- [x] Build completes successfully
- [x] Enhanced logging shows profit calculations
- [x] Multi-DEX price feeds are active
- [x] Slippage protection is functioning
- [x] Opportunity ranking is operational
- [x] Gas price updates are working
- [x] Memory usage is within limits
- [x] No critical errors in logs

### 🚀 Deployment Commands

**Start the Enhanced MEV Bot:**
```bash
# Production start command
env ARBITRUM_RPC_ENDPOINT="<your-rpc>" \
    ARBITRUM_WS_ENDPOINT="<your-ws>" \
    MEV_BOT_ENCRYPTION_KEY="<your-key>" \
    METRICS_ENABLED="true" \
    LOG_LEVEL="info" \
    ./mev-bot start
```
