The Ultimate Smart Contract Audit Checklist

June 28, 2024

Think of an audit as a security team inspecting your code for bugs, vulnerabilities, and loopholes that bad actors could exploit. It’s not just about ticking boxes; it’s about catching hidden flaws that could cost you and your users dearly.

Here’s your ultimate smart contract audit checklist, explained in simple terms:

Before the Audit

Clean Your Code

Review your code line by line, fix any known errors, and ensure it’s well-documented and easy to understand. Use tools like Slither, Mythril, or Bunzz Audit (launching soon) to automatically scan your code for vulnerabilities. Clear comments and explanations within your code will also aid in the understanding.

Define Your Scope

What functionalities does your contract have? What are its potential attack vectors? Clearly outlining your goals and concerns helps with the auditing process. Highlight areas in the code handling funds, access control, and critical operations. Think like a hacker and consider ways someone might exploit your contract.

During the Audit

Fix the Vulnerabilities

Take identified issues seriously and fix them promptly. Tools like STRIDE or PASTA can systematically identify potential threats. Don’t ignore warnings; even seemingly minor flaws can be disastrous.

Test and Re-audit if Needed

Write individual tests for each function to ensure they behave as expected and how different parts of your contract interact. Tools like sFuzz can randomly generate inputs and stress-test your contract.

After the Audit

Stay Vigilant and Re-audit

Security is an ongoing process, not a one-time fix. Depending on the level of threat, a re-audit might be necessary to ensure everything is patched up tight. Keep your contract updated, monitor its activity, and be prepared to respond to new threats.

Continue Monitoring

Actively monitor your deployed contract for suspicious activity and stay updated on emerging threats and vulnerabilities.

Deploying an unaudited smart contract is gambling with your users’ trust and your reputation. Don’t take the risk! Follow this checklist and take security seriously.

Additional Tips

  • No Tool is Perfect: Each tool has limitations and potential false positives. Combine results from multiple tools and manual reviews for a comprehensive assessment.
  • Testing is Not Exhaustive: You can’t test every possible scenario. Focus on high-risk areas and continuously improve your testing strategies.
  • Involve the Community: Consider sharing your code with trusted colleagues or security experts for fresh perspectives and vulnerability discovery.

By being proactive and taking the necessary steps, you can ensure your smart contract is a success story, not a cautionary tale.

Conclusion

Internal smart contract audits are a complex task, demanding expertise, meticulous planning, and ongoing vigilance. While this guide provides a framework, remember that security is a journey, not a destination. Continuously learn, adapt, and seek external expertise when needed.

Remember, the security of your smart contract relies on how well your internal audit process is. Tread carefully, prepare well, and audit with confidence.
