What is a Smart Contract Audit?

This CertiK-oriented guide outlines the smart contract auditing lifecycle, risk classifications (Critical to Informational), common vulnerabilities encountered in DeFi/NFT projects (centralization risks, missing event emissions, unlocked compiler versions, input validation failures, and reliance on third-party contracts), and how security scoring and monitoring tools (Security Leaderboard, Skytrace, Skynet, Security Oracle) influence a project's security posture.
