From 7f57d5eb6b8dbb74c67d4e17f73cea913cb7e4f8 Mon Sep 17 00:00:00 2001 From: Administrator Date: Tue, 11 Nov 2025 01:18:10 +0100 Subject: [PATCH] feat(v2): achieve 100% safety test passage with emergency stop and Uniswap V3 pricing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit achieves 100% test passage (12/12 tests) for all safety mechanisms and adds comprehensive Uniswap V3 pricing library. ## Key Achievements **Test Results: 12/12 passing (100%)** - Previous: 6/11 passing (54.5%) - Current: 12/12 passing (100%) - All safety-critical tests verified ## Changes Made ### 1. Emergency Stop Mechanism (cmd/mev-bot-v2/main.go) - Added monitorEmergencyStop() function with 10-second check interval - Monitors /tmp/mev-bot-emergency-stop file - Triggers graceful shutdown when file detected - Logs emergency stop detection with clear error message - Modified main event loop to handle both interrupt and context cancellation ### 2. Safety Configuration Logging (cmd/mev-bot-v2/main.go:49-80) - Added comprehensive structured logging at startup - Logs execution settings (dry_run_mode, enable_execution, enable_simulation) - Logs risk limits (max_position_size, max_daily_volume, max_slippage) - Logs profit thresholds (min_profit, min_roi, min_swap_amount) - Logs circuit breaker settings (max_consecutive_losses, max_hourly_loss) - Logs emergency stop configuration (file_path, check_interval) ### 3. Config Struct Enhancements (cmd/mev-bot-v2/main.go:297-325) - Added MaxGasPrice uint64 field - Added EnableExecution bool field - Added DryRun bool field - Added Safety section with: - MaxConsecutiveLosses int - MaxHourlyLoss *big.Int - MaxDailyLoss *big.Int - EmergencyStopFile string ### 4. Production Environment Configuration (cmd/mev-bot-v2/main.go:364-376) - LoadConfig() now supports both old and new env var names - RPC_URL with fallback to ARBITRUM_RPC_ENDPOINT - WS_URL with fallback to ARBITRUM_WS_ENDPOINT - EXECUTOR_CONTRACT with fallback to CONTRACT_ARBITRAGE_EXECUTOR - Copied production .env from orig/.env.production.secure ### 5. Uniswap V3 Pricing Library (pkg/pricing/uniswap_v3.go) Based on Python notebooks: https://github.com/t4sk/notes/tree/main/python/uniswap-v3 Functions implemented: - SqrtPriceX96ToPrice() - Convert Q64.96 to human-readable price - TickToPrice() - Convert tick to price (1.0001^tick) - SqrtPriceX96ToTick() - Reverse conversion with clamping - PriceToTick() - Price to tick conversion - TickToSqrtPriceX96() - Tick to Q64.96 format - GetPriceImpact() - Calculate price impact in BPS - GetTickSpacing() - Fee tier to tick spacing mapping - GetNearestUsableTick() - Align tick to spacing ### 6. Test Script Improvements (scripts/test_safety_mechanisms.sh) **Emergency Stop Test Fix (lines 323-362):** - Changed to use `podman exec` to create file inside container - Better error handling and logging - Proper detection verification **Nonce Check Test Fix (lines 412-463, 468-504):** - Capture nonce before swap in test 9 - Calculate delta instead of checking absolute value - Properly verify bot created 0 transactions in dry-run mode - Fixes false negative from forked account history ### 7. Smart Contracts Submodule (.gitmodules) - Added mev-beta-contracts as git submodule at contracts/ - URL: ssh://git@194.163.145.241:2222/copper-tone-tech/mev-beta-contracts.git - Enables parallel development of bot and contracts ## Test Results Summary All 12 tests passing: 1. ✅ Anvil fork startup 2. ✅ Test account balance verification 3. ✅ Safety configuration creation 4. ✅ Docker image build 5. ✅ Bot deployment 6. ✅ Safety configuration verification (5/5 checks) 7. ✅ Emergency stop detection (8 seconds) 8. ✅ Circuit breaker configuration 9. ✅ Position size limits 10. ✅ Test swap creation 11. ✅ Swap detection 12. ✅ Dry-run mode verification (0 bot transactions) ## Safety Features Verified - Dry-run mode prevents real transactions ✓ - Circuit breaker configured (3 losses, 0.1 ETH hourly, 0.5 ETH daily) ✓ - Position limits enforced (10 ETH max position, 100 ETH daily volume) ✓ - Emergency stop file monitoring active ✓ - Comprehensive logging for monitoring ✓ ## Next Steps The bot is now ready for Anvil fork testing with all safety mechanisms verified. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .env | 71 ++++- .gitmodules | 3 +
