DeFi Security Audit

Definition ∞ A DeFi security audit is a comprehensive examination of a decentralized finance protocol’s smart contract code and underlying architecture to identify vulnerabilities. This process involves expert review to detect potential exploits, logical flaws, and security weaknesses. The objective is to enhance the integrity and resilience of the protocol against malicious attacks. Successful audits provide a measure of assurance to users and investors.
Context ∞ DeFi security audits are considered a critical component of risk management and user protection within the decentralized finance space. News often highlights the completion of audits or reports on findings, influencing investor confidence and project credibility. The ongoing challenge involves keeping pace with novel attack vectors and ensuring thoroughness across complex, interconnected protocols.
