# Deployment and Monitoring Plan

## Overview

This document outlines the deployment strategy and monitoring requirements for the exchange-specific helper libraries in the MEV bot project.

## Deployment Strategy

### Environment Configuration
- Development: Local environment with testnet contracts
- Staging: Private network with mainnet contracts
- Production: Mainnet with proper security measures

### Deployment Process
1. Automated build and compilation
2. Pre-deployment validation checks
3. Staging environment testing
4. Production deployment
5. Post-deployment health verification

### Configuration Management
- Environment-specific configuration files
- Secure credential management
- Feature flagging for gradual rollouts
- Contract address management per network
- API key and endpoint management

## Monitoring Requirements

### Performance Metrics
- API response times
- Transaction execution latency
- Gas cost tracking
- Throughput measurements
- Success/failure rates

### Business Metrics
- Number of successful swaps
- Liquidity operations executed
- Arbitrage opportunities captured
- Profitability tracking
- Exchange utilization rates

### System Metrics
- Memory usage
- CPU utilization
- Network I/O
- Database performance
- Error rates

## Alerting System

### Critical Alerts
- Failed transactions
- Security incidents
- Significant performance degradation
- Profitability drops
- Exchange connectivity issues

### Warning Alerts
- High slippage in trades
- Low liquidity pools
- Unusual price differences
- API rate limiting
- Memory usage approaching limits

### Monitoring Tools
- Prometheus for metrics collection
- Grafana for dashboard visualization
- AlertManager for notification routing
- ELK stack for log analysis
- Custom health check endpoints

## Logging Strategy

### Log Levels
- DEBUG: Detailed diagnostic information
- INFO: General operational information
- WARN: Potential issues requiring attention
- ERROR: Problems in operation
- CRITICAL: Critical problems requiring immediate attention

### Log Content
- Transaction details and outcomes
- Performance metrics
- Error stack traces
- Exchange communication logs
- Profitability calculations

### Log Management
- Structured logging format (JSON)
- Centralized log aggregation
- Log retention policies
- Log rotation and archival
- Searchable log indices

## Security Monitoring

### Anomaly Detection
- Unusual transaction patterns
- Abnormal gas consumption
- Unexpected contract interactions
- Suspicious API access patterns
- Deviation from expected behavior

### Compliance Tracking
- Transaction volume monitoring
- Profit reporting
- Risk exposure tracking

- Security vulnerabilities
- Significant profit degradation
- Unforeseen side effects

### Rollback Procedures
- Version rollback to last known good state
- Configuration rollback
- Database migration reversal
- Health check verification
- Communication to stakeholders

## Backup and Recovery

### Data Backup
- Configuration files
- Transaction history
- Performance metrics
- Log archives
- Database snapshots

### Recovery Procedures
- System restoration from backups
- Data integrity verification
- Service verification
- Communication to stakeholders
- Post-recovery validation

## Performance Optimization
