💡 Key Insights

From Profitability Analysis

1. Code Quality: Excellent (92% complete, <1% math error)
2. Strategy Limitation: Only 1 DEX, 2-hops, no alternatives
3. Market Exists: 5,058 opportunities/day (just not profitable yet)
4. Clear Solution: Multi-DEX + multi-hop + sandwiches

From Multi-DEX Implementation

1. Protocol Abstraction: DEXDecoder interface enables easy expansion
2. Parallel Execution: 2-3x faster than sequential queries
3. Type Compatible: Seamless integration with existing bot
4. Extensible: Adding new DEXes requires only implementing one interface
