Smart contract security audit — 10 DeFi bug classes (accounting desync, access control, incomplete path, off-by-one, oracle, ERC4626, reentrancy, flash loan, signature replay, proxy), pre-dive kill signals (TVL < $500K etc), Foundry PoC template, grep patterns for each class, and real Immunefi paid examples. Use for any Solidity/Rust contract audit or when deciding whether a DeFi target is worth hunting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WEB3 SMART CONTRACT AUDIT 10 bug classes. Pre-dive kill signals. Foundry PoC template. Real paid examples. --- ## PRE-DIVE KILL SIGNALS (check BEFORE any code review) > ZKsync lesson: $322M TVL + OZ audit + 750K LOC + 5 sessions = 0 findings. Large well-audited bridges are extremely hard. 1. **TVL < $500K** → max payout capped too low for effort 2. **2+ top-tier audits** (Halborn, ToB, Cyfrin, OpenZeppelin) on simple protocol → bugs already found 3. **Protocol < 500 lines, single A→B→C flow** → minimal attack surface 4. **Formula**: `max_realistic_payout = min(10% × TVL, program_cap)` — if < $10K, skip **Soft kill:** OZ/ToB/Cyfrin audit on current version + codebase > 500K LOC → expect 40+ hours for maybe 1 finding. Only proceed if bounty floor > $50K AND you have protocol-specific expertise. **Target scoring (go if >= 6/10):** - TVL > $10M: +2 - Immunefi program with Critical >= $50K: +2 - No top-tier audit on current version: +2 - < 30 days since deploy: +1 - Protocol you've hunted before: +1 - Source code + natspec comments: +1 - Upgradeable proxies: +1 --- ## THE ONE RULE …

How to install
mdr add mikacr1138/claude-bug-bounty/web3-audit@sha256:947c36bc2184328aThe line at the top of this page pins the label git:20260317.a154787, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
