Package Descriptions
Monitor Package
Responsible for real-time monitoring of the Arbitrum sequencer, detecting L2 messages and transactions, and subscribing to DEX events.
Events Package
Parses and processes DEX interaction events, converting raw blockchain data into structured information for analysis.
Market Package
Manages market data, including pool information, token metadata, and pricing data. Implements caching and concurrent processing.
Scanner Package
Scans the market for potential arbitrage opportunities using worker pools and sophisticated algorithms.
Arbitrage Package
Implements the core arbitrage detection and execution logic, including profitability calculations and transaction management.
Configuration Package
Handles configuration loading from YAML files and environment variables, with validation and security features.
Logger Package
Provides structured logging with separation of concerns, security filtering, and performance optimization.
Security Package
Manages private keys, transaction signing, rate limiting, and audit logging for all security-sensitive operations.
