Common DeFi smart contract vulnerability classes include accounting desync, access control issues, incomplete paths, off-by-one errors, oracle manipulation, and proxy or upgrade bugs. Reviewing these bug classes during security audits helps identify systemic root causes and recurring exploit patterns in Solidity protocols.

To find oracle manipulation and accounting desync bugs in Solidity code, apply ready-to-use grep patterns to scan for specific vulnerability signatures. This reference provides search patterns alongside real-world case studies from Immunefi and DeFiHack to pinpoint root causes during code reviews.

Yes, this reference supports bug hunting on Immunefi and live protocol assessments by providing real-world case studies and attack reproductions. It covers root causes, vulnerability patterns, and mitigations across 10 distinct DeFi bug classes applicable to active smart contract security reviews.

The best way to structure a bug hunting playbook for DeFi smart contracts is to organize it by vulnerability class. This reference covers 10 distinct bug classes with root causes, grep patterns, and real-world examples, enabling a systematic approach to secure code reviews and protocol assessments.

Yes, this covers proxy and upgrade vulnerabilities in smart contracts as one of its 10 core DeFi bug classes. It details the root causes and patterns associated with upgrade bugs, providing grep patterns and real-world examples to detect these issues during Solidity security audits.
