Maximal Extractable Value (MEV) represents the maximum value that can be extracted from block production in excess of the standard block rewards and gas fees. On Solana, MEV opportunities arise from:
- Transaction ordering
- Price discrepancies across DEXs
- Liquidation opportunities
- Sandwich trading
- Just-In-Time (JIT) Liquidity
Solana's unique characteristics make it particularly suitable for MEV extraction:
- High throughput (65,000+ TPS)
- Sub-second finality
- Low transaction costs
- Rich DeFi ecosystem
-
High-Speed Transaction Processing
- Custom transaction optimization
- Parallel transaction execution
- Memory-pooling for reduced latency
- Advanced mempool monitoring
-
Advanced Strategy Implementation
- Multiple strategy support
- Strategy composition
- Dynamic strategy switching
- Risk management integration
-
Real-Time Analytics
- Performance metrics
- Strategy effectiveness tracking
- Risk exposure monitoring
- Profit/loss analysis
-
Network Optimization
- Direct RPC node connections
- Custom RPC endpoint management
- Network latency optimization
- Redundant connection handling
-

The bot operates based on a series of logical steps to identify and execute profitable MEV opportunities. The following flowchart illustrates the bot's logic:

- Monitor Mempool: Continuously observe the mempool for new transactions.
- Identify Opportunity: Analyze incoming transactions to identify potential MEV opportunities.
- Execute Strategy: Depending on the identified opportunity, execute the corresponding strategy (arbitrage, liquidation, sandwich trading, or JIT liquidity).
- Log Results: Record the outcomes of executed strategies for performance analysis and optimization.
- Rust 1.65 or higher
- Solana CLI tools
- Linux/Unix-based OS (recommended)
- Minimum 16GB RAM
- SSD storage
