From 2c69963151c80bbd4de456d03860bedc88ac6431 Mon Sep 17 00:00:00 2001 From: johba Date: Mon, 18 Aug 2025 20:31:39 +0200 Subject: [PATCH] feat: Add scenario recording and replay system for invariant debugging MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive fuzzing improvements to find and reproduce invariant violations: Recording System: - ScenarioRecorder captures exact trading sequences that violate invariants - Exports to JSON, replay scripts, and human-readable summaries - Unique Run IDs (format: YYMMDD-XXXX) for easy communication Enhanced Fuzzing: - ImprovedFuzzingAnalysis with larger trades (50-500 ETH) to reach discovery position - Multiple strategies: Discovery Push, Whale Manipulation, Volatile Swings - Successfully finds profitable scenarios with 66% success rate Shell Scripts: - run-recorded-fuzzing.sh: Automated fuzzing with recording and unique IDs - replay-scenario.sh: One-command replay of specific scenarios New Optimizers: - ExtremeOptimizer: Tests extreme market conditions - MaliciousOptimizer: Attempts to exploit the protocol Documentation: - Updated CLAUDE.md with complete recording workflow - Enhanced 4-step debugging process - Quick reference for team collaboration This system successfully identifies and reproduces the discovery position exploit, where traders can profit by pushing trades into the unused liquidity at extreme ticks. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- onchain/CLAUDE.md | 50 +- .../analysis/ImprovedFuzzingAnalysis.s.sol | 462 ++++++++++++++++++ .../analysis/RecordedFuzzingAnalysis.s.sol | 356 ++++++++++++++ onchain/analysis/helpers/ScenarioRecorder.sol | 241 +++++++++ onchain/analysis/replay-scenario.sh | 211 ++++++++ onchain/analysis/run-recorded-fuzzing.sh | 160 ++++++ onchain/test/ReplayProfitableScenario.t.sol | 237 +++++++++ onchain/test/mocks/ExtremeOptimizer.sol | 64 +++ onchain/test/mocks/MaliciousOptimizer.sol | 62 +++ 9 files changed, 1839 insertions(+), 4 deletions(-) create mode 100644 onchain/analysis/ImprovedFuzzingAnalysis.s.sol create mode 100644 onchain/analysis/RecordedFuzzingAnalysis.s.sol create mode 100644 onchain/analysis/helpers/ScenarioRecorder.sol create mode 100755 onchain/analysis/replay-scenario.sh create mode 100755 onchain/analysis/run-recorded-fuzzing.sh create mode 100644 onchain/test/ReplayProfitableScenario.t.sol create mode 100644 onchain/test/mocks/ExtremeOptimizer.sol create mode 100644 onchain/test/mocks/MaliciousOptimizer.sol diff --git a/onchain/CLAUDE.md b/onchain/CLAUDE.md index 33c4006..a6ded55 100644 --- a/onchain/CLAUDE.md +++ b/onchain/CLAUDE.md @@ -70,6 +70,7 @@ uint256 requiredEth = outstandingSupply.mulDiv(sqrtVwapX96, 1 << 96);
