Smart contract audit processes involve triaging DeFi targets with pre-dive kill signals to gauge ROI, then scanning codebases using grep patterns to detect 10 common bug classes like reentrancy and oracle manipulation before deep review.

Common DeFi exploit primitives include accounting state desync, access control failures, oracle manipulation, reentrancy, flash-loan exploitation, signature replay, and proxy upgrade issues. You should systematically check for these 10 bug classes during threat modeling.

You use a Foundry PoC template to turn vulnerability hypotheses into reproducible proofs of concept. After identifying a potential exploit using grep patterns, outline a single Foundry test plan to validate the highest-probability issue.

Yes, you can use bug-class-specific grep patterns for rapid codebase scanning to find reentrancy, flash-loan exploitation, and other Solidity vulnerabilities. These concrete audit mechanics help identify risky code paths quickly.

You evaluate DeFi protocols for Immunefi bounties by applying pre-dive kill signals that use TVL, prior top-tier audits, protocol complexity, and bounty floor heuristics. This fast ROI gating determines if the target is worth a deep review.

This audit approach applies to both Solidity or Rust contract audits. It uses YAML-guided operational steps to threat-model DeFi protocols and prepare Immunefi-style investigations across common exploit primitives for either language.
