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.

# 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
