Frequently Asked Questions
A smart contract audit is a thorough analysis of a codebase in order to correct design issues, errors in the code, or security vulnerabilities.
To verify whether a project has undergone an audit by Quantstamp, you can access our public audit reports at certificate.quantstamp.com. These reports include detailed information about the specific repository that was audited for the project in question. Many of our clients choose to publicly list their audit reports here for added transparency.
Begin by requesting an audit and giving us details about your team and project. Someone from our team will reach out to gather any additional information we need, give you a customized quote, and schedule a kickoff meeting.
During this initial phase, we’ll discuss any expected timelines, details or resources we need from you to get started. Following the audit, you'll receive a detailed initial report that outlines our findings and recommendations. This report provides an opportunity for you and your team to address any vulnerabilities listed. Once you've made the necessary fixes, our team will review these and provide an updated, final report.
The duration and cost of a smart contract audit can vary significantly based on the size and complexity of your project. Smart contracts can range from a few thousand lines of code to tens of thousands, so it’s impossible to provide a fixed cost without a good understanding of the project scope.
Audit timeline also depends on various factors: codebase length, complexity, documentation quality, and the extent of communication required with our team. Please get in touch with us and we can provide a custom quote based on your unique project
