- Created UniswapV2Parser with Swap event parsing - Manual ABI decoding for reliability and performance - Token extraction from pool cache - Proper decimal handling (6, 8, 18 decimals) - Mint/Burn events recognized but ignored for MVP - Receipt parsing for multi-event transactions - Comprehensive test suite with 14 test cases - Test helpers for reusable mock logger and ABI encoding - Factory registration via NewDefaultFactory() - Defensive programming (nil logger allowed) Coverage: 86.6% on uniswap_v2.go Tests: All 14 test cases passing Lines: ~240 implementation, ~400 tests Fast MVP: Week 1, Days 1-2 ✅ COMPLETE 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
