Code Audit Failure

Definition ∞ A Code Audit Failure is the situation where a formal examination of software code fails to identify critical security flaws or vulnerabilities. In the context of digital assets and blockchain, this means that a smart contract or protocol, despite undergoing an audit, contains exploitable weaknesses that could lead to loss of funds or system malfunction. Such failures undermine confidence in the audited code’s integrity.
Context ∞ Reports of code audit failures frequently surface following security incidents in the cryptocurrency space. This prompts ongoing debate regarding the thoroughness of auditing processes, the qualifications of auditors, and the need for supplementary verification methods beyond standard code reviews to prevent breaches.
