To audit smart contracts for DeFi vulnerabilities, catalog and analyze codebases against 10 known bug classes, apply pre-dive kill signals for risk triage, and use grep patterns to accelerate evidence collection across Solidity and Rust targets.

Common DeFi smart contract bug classes include accounting desync, access control, incomplete path, off-by-one, oracle, ERC4626, reentrancy, flash loan, signature replay, and proxy vulnerabilities, each with explicit detection patterns and remediation guidance.

Reproduce a smart contract vulnerability with a Foundry PoC by applying the provided Foundry template against your Solidity project to validate and demonstrate findings mapped to specific DeFi bug classes during security audits.

Yes, you can use grep patterns to find reentrancy and oracle bugs in Solidity by scanning codebases for the ten identified vulnerability classes, speeding up detection and evidence collection before deep code review.

Yes, you need Foundry installed as part of a standard audit setup, access to contract sources, and familiarity with grep-based pattern searches to map findings to bug classes and run Proof of Concept templates.

Immunefi paid examples are used to benchmark smart contract severity by illustrating real vulnerability payouts, enabling auditors to map reproduced findings to historical bounties and assess exploit impact accurately.
