CRITICAL BUG FIX: - MultiHopScanner.updateTokenGraph() was EMPTY - adding no pools! - Result: Token graph had 0 pools, found 0 arbitrage paths - All opportunities showed estimatedProfitETH: 0.000000 FIX APPLIED: - Populated token graph with 8 high-liquidity Arbitrum pools: * WETH/USDC (0.05% and 0.3% fees) * USDC/USDC.e (0.01% - common arbitrage) * ARB/USDC, WETH/ARB, WETH/USDT * WBTC/WETH, LINK/WETH - These are REAL verified pool addresses with high volume AGGRESSIVE THRESHOLD CHANGES: - Min profit: 0.0001 ETH → 0.00001 ETH (10x lower, ~$0.02) - Min ROI: 0.05% → 0.01% (5x lower) - Gas multiplier: 5x → 1.5x (3.3x lower safety margin) - Max slippage: 3% → 5% (67% higher tolerance) - Max paths: 100 → 200 (more thorough scanning) - Cache expiry: 2min → 30sec (fresher opportunities) EXPECTED RESULTS (24h): - 20-50 opportunities with profit > $0.02 (was 0) - 5-15 execution attempts (was 0) - 1-2 successful executions (was 0) - $0.02-$0.20 net profit (was $0) WARNING: Aggressive settings may result in some losses Monitor closely for first 6 hours and adjust if needed Target: First profitable execution within 24 hours 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
