Complete local testing setup with Anvil fork of Arbitrum mainnet: Infrastructure: - Docker Compose orchestration (Anvil, MEV Bot, Prometheus, Grafana) - Anvil fork configuration with 1-second blocks - Multi-stage Dockerfile for optimized builds - Health checks and auto-restart policies Configuration: - Comprehensive .env.example with all parameters - Prometheus metrics collection setup - Grafana datasource provisioning - .gitignore to prevent committing secrets Testing Scripts: - setup-local-fork.sh: Initialize fork and fund test wallet - create-test-swap.sh: Generate test swaps for bot detection - Both scripts include validation and helpful output Integration Components: - pkg/sequencer/reader.go: WebSocket reader for pending transactions - Worker pool pattern (10 workers) - <50ms processing target - Front-running capability - Auto-reconnection with exponential backoff - pkg/pools/discovery.go: Pool discovery service - UniswapV2-style pools (SushiSwap, Camelot) - UniswapV3 pools (multiple fee tiers) - Factory contract queries - Liquidity filtering Documentation: - TESTING.md: Complete testing guide - Quick start instructions - Testing scenarios - Monitoring and debugging - Performance benchmarks - Troubleshooting guide This enables safe local testing without deploying to public testnet, using real Arbitrum mainnet state forked locally with Anvil. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
