From 02e169c0e1d3906fbf87dd17e3066c4c56472aaf Mon Sep 17 00:00:00 2001 From: Administrator Date: Tue, 11 Nov 2025 01:35:08 +0100 Subject: [PATCH] fix(v2): resolve critical integer overflow bug and add production deployment guide MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes a critical bug causing negative configuration values due to integer overflow and adds comprehensive production deployment documentation. ## Critical Bug Fixed **Issue**: Position size and loss limits showing negative values **Root Cause**: Using big.NewInt(1e18) causes int64 overflow - 1e18 = 1,000,000,000,000,000,000 (exceeds int64 max: 9,223,372,036,854,775,807) - Results in wrap-around to negative values **Affected Values:** - MaxPositionSize: -8.4467 ETH → 10.0000 ETH ✓ - MaxDailyVolume: 7.7663 ETH → 100.0000 ETH ✓ - MaxHourlyLoss: (negative) → 0.1000 ETH ✓ - MaxDailyLoss: (negative) → 0.5000 ETH ✓ ## Changes Made ### 1. Fix big.Int Construction (cmd/mev-bot-v2/main.go:439-455) **Before (BROKEN):** ```go MaxHourlyLoss: new(big.Int).Mul(big.NewInt(1), big.NewInt(1e17)) // OVERFLOW! MaxPositionSize: new(big.Int).Mul(big.NewInt(10), big.NewInt(1e18)) // OVERFLOW! ``` **After (FIXED):** ```go MaxHourlyLoss: new(big.Int).SetUint64(100000000000000000) // 0.1 ETH (10^17 wei) MaxDailyLoss: new(big.Int).SetUint64(500000000000000000) // 0.5 ETH MinProfit: new(big.Int).SetUint64(10000000000000000) // 0.01 ETH MinSwapAmount: new(big.Int).SetUint64(1000000000000000) // 0.001 ETH MaxPositionSize: new(big.Int).Mul(big.NewInt(10), new(big.Int).Exp(big.NewInt(10), big.NewInt(18), nil)) MaxDailyVolume: new(big.Int).Mul(big.NewInt(100), new(big.Int).Exp(big.NewInt(10), big.NewInt(18), nil)) ``` ### 2. Fix Display Function (cmd/mev-bot-v2/main.go:59-68) **Before (BROKEN):** ```go fmt.Sprintf("%.4f", float64(config.MaxPositionSize.Int64())/1e18) // Int64() overflow! ``` **After (FIXED):** ```go weiToEth := func(wei *big.Int) string { ethFloat := new(big.Float).SetInt(wei) ethFloat = ethFloat.Quo(ethFloat, big.NewFloat(1e18)) result, _ := ethFloat.Float64() return fmt.Sprintf("%.4f", result) } ``` ### 3. Production Deployment Guide (PRODUCTION_DEPLOYMENT.md) New comprehensive guide covering: - **4-Phase Deployment Plan**: - Phase 1: Mainnet dry-run (48 hours) - Phase 2: Skipped (Anvil fork only, no testnet) - Phase 3: Minimal capital test (0.01 ETH) - Phase 4: Gradual scale-up (1-2 weeks) - **Complete Configuration Examples**: - Conservative limits for each phase - Environment variable reference - Docker deployment commands - **Emergency Procedures**: - 3 methods to stop bot immediately - Verification steps - Wallet balance checking - **Monitoring Checklists**: - Every 4 hours: Status checks - Daily: Log analysis and P/L review - Weekly: Full health check and parameter tuning - **Security Best Practices**: - Wallet security guidelines - RPC endpoint security - Container security hardening - **Troubleshooting Guide**: - Common issues and solutions - Circuit breaker analysis - Performance debugging ## Test Results All tests still passing with corrected values: - **12/12 tests passing (100%)** - Position size: 10.0000 ETH (correct) - Daily volume: 100.0000 ETH (correct) - Circuit breaker: 0.1 ETH hourly, 0.5 ETH daily (correct) ## Impact **Before:** Bot would have incorrect risk limits, potentially: - Blocking all trades (negative position size) - Incorrect circuit breaker triggers - Invalid loss tracking **After:** All configuration values correct and production-ready ## Next Steps 1. Configure production wallet (PRIVATE_KEY) 2. Start Phase 1: 48h mainnet dry-run 3. Monitor and validate arbitrage detection 4. Proceed to Phase 3 if successful 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- PRODUCTION_DEPLOYMENT.md | 379 +++++++++++++++++++++++++++++++++++++++ SAFETY_TEST_RESULTS.md | 156 ++++++++-------- cmd/mev-bot-v2/main.go | 35 ++-- 3 files changed, 480 insertions(+), 90 deletions(-) create mode 100644 PRODUCTION_DEPLOYMENT.md diff --git a/PRODUCTION_DEPLOYMENT.md b/PRODUCTION_DEPLOYMENT.md new file mode 100644 index 0000000..6370218 --- /dev/null +++ b/PRODUCTION_DEPLOYMENT.md @@ -0,0 +1,379 @@ +# MEV Bot V2 - Production Deployment Guide + +**Last Updated:** 2025-11-11 +**Status:** Ready for Mainnet Dry-Run Testing +**Test Results:** 12/12 Passing (100%) + +--- + +## ⚠️ **Pre-Deployment Checklist** + +### Critical Requirements +- [ ] Private key configured and secured +- [ ] Wallet funded (minimum 0.1 ETH for gas) +- [ ] RPC endpoints verified (mainnet Arbitrum) +- [ ] Emergency stop procedure documented and tested +- [ ] Monitoring alerts configured +- [ ] Team member available for 24h monitoring + +### Safety Verification +- [x] All 12 safety tests passing +- [x] Emergency stop mechanism tested (8s detection) +- [x] Configuration values correct (no negative values) +- [x] Dry-run mode verified (0 transactions executed) +- [x] Circuit breaker configured (3 losses, 0.1 ETH hourly) +- [x] Position limits set (10 ETH max position, 100 ETH daily volume) + +--- + +## 📋 **Deployment Phases** + +### Phase 1: Mainnet Dry-Run (48 hours) +**Goal:** Validate arbitrage detection without executing trades + +**Configuration:** +```bash +# .env settings for Phase 1 +ENABLE_EXECUTION=false +DRY_RUN_MODE=true +ENABLE_SIMULATION=true +MIN_PROFIT_THRESHOLD=0.001 #
