Definition ∞ A custom code audit is a specialized review process for examining bespoke software programs, particularly smart contracts, for security flaws or logical errors. Independent security experts meticulously analyze the source code to identify vulnerabilities, inefficiencies, or deviations from intended functionality. This rigorous inspection aims to enhance the reliability and safety of digital asset protocols. It is a critical step before deploying new blockchain applications.
Context ∞ The security of smart contracts and decentralized applications frequently depends on thorough custom code audits. A primary concern within the industry is the scarcity of highly skilled auditors and the ongoing threat of sophisticated exploits. Continuous auditing practices and formal verification methods are gaining prominence to address evolving security challenges.
