Before diving into the code, auditors perform an initial assessment to understand the purpose of the smart contract, its interactions, and its dependencies. This phase involves reviewing the project’s documentation, whitepaper, and any available test cases.
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
Enhanced Security: Audits help identify and fix vulnerabilities, making smart contracts more secure and resilient against attacks.
Operational Efficiency: By identifying inefficiencies in the code, audits can optimize the smart contract’s performance, reducing operational costs and improving speed.

Multi-Phase Audits
Modern audits often involve multiple phases, each focusing on different aspects of the smart contract. This approach ensures a comprehensive review and helps catch vulnerabilities that might be missed in a single round of auditing.
Initial Code Review: The audit begins with a detailed review of the smart contract code to identify obvious bugs and vulnerabilities.
Dynamic Analysis: Next, the contract is executed in a controlled environment to observe its behavior and identify any runtime issues.
Security Analysis: Specialized tools and experts analyze the code for security weaknesses, including common vulnerabilities like reentrancy attacks, integer overflows, and improper access control.
Remediation and Re-Audit: After vulnerabilities are fixed, the contract undergoes another round of auditing to ensure that the fixes have been implemented correctly and that no new issues have been introduced.
Red Team vs. Blue Team Audits
Inspired by traditional cybersecurity practices, some DeFi projects employ a red team vs. blue team approach to smart contract audits. In this methodology, two teams are formed:
Red Team: The red team actively tries to exploit vulnerabilities in the smart contract, mimicking an attacker’s approach.
Blue Team: The blue team, representing the developers, defends the contract, working to fix any issues identified by the red team.
This dynamic and interactive approach can uncover vulnerabilities that static and dynamic analysis might miss.
