Code Review
The heart of the audit process is the code review. This phase can be broken down into several sub-phases:
Static Analysis: Auditors employ tools to analyze the code without executing it. Static analysis helps identify obvious bugs, inefficiencies, and potential vulnerabilities.
Dynamic Analysis: Here, auditors execute the smart contract in a controlled environment to observe its behavior. This phase helps uncover issues that static analysis might miss.
Manual Code Review: Experienced auditors manually review the code to ensure that all identified vulnerabilities have been addressed and to catch any missed issues by automated tools.
Reporting and Remediation
Once vulnerabilities are identified, auditors compile a detailed report outlining their findings. This report typically includes:
After receiving the report, the contract developers make the necessary changes to remediate the vulnerabilities. The cycle may repeat if new issues are found during subsequent audits.
Benefits of Smart Contract Audits
