The audit process

What is a smart contract audit?

A smart contract security audit is a comprehensive process where one or more security researchers review a smart contract or protocol codebase to find, report, and mitigate critical security vulnerabilities that will disrupt your services.

1

Setup timelines and onboarding

Our engineers will estimate the timeline based on codebase complexity and size and open a line of communication.

2

Lock commit hash & start date

We agree on a start date and a commit hash to base our audit. To get the most out of a security audit, we recommend that this commit hash not change during the audit.

3

Audit begins

Our engineers will spend the allotted time on your contracts. We strongly recommend keeping an open communication channel between us and your engineers during this process.

4

Initial audit report

The initial report will explain each issue categorized as High, Medium, Low or Informational. We will set up a call with your engineers to ask questions about the findings.

5

Mitigation

Your engineers will have a chance to mitigate the findings using the recommendations in the report.

6

Final audit report

Once the mitigations have been applied, our engineers will check them and amend the issues on the report as "Acknowledged" or "Resolved" with any necessary extra information.
