The cryptocurrency industry faces a significant security challenge that cannot be resolved through standard audits alone. Audits provide a snapshot of a protocol's security at a specific time, but they do not guarantee ongoing safety, especially as protocols evolve. Changes in contracts, infrastructure, governance, or operations can alter a protocol's security posture, making the "fully audited" label potentially misleading. Recent incidents, such as the KelpDAO hack, highlight the risks that extend beyond code vulnerabilities, affecting user confidence in the crypto ecosystem. To achieve mass adoption, the industry must adopt a defense-in-depth strategy, combining thorough code reviews with robust operational security and comprehensive internal training, rather than relying solely on audits.
