"When developing our Plasma MVP Implementation, we wanted to have strong security guarantees. As a scalability solution, our plasma implementations could potentially be handling massive transaction volumes. Quantstamp has audited large-scale, mission-critical initiatives in the past, and working with Quantstamp was an obvious decision to make."

Vansa Chatikavanij

CEO of OmiseGO

“Quantstamp was great to work with. They were professional and efficient when working with us to make sure that our production contracts were secure. Their comprehensive analysis resulted in an easy to use audit report that showed where things could be improved and ultimately gave us confidence in our smart contracts.”

Mick Hagen

Founder & CEO

“Quantstamp’s audit process was comprehensive and streamlined. They provided thorough feedback in addition to an audit certificate and auditor’s opinion letter that gave our stakeholders confidence in our smart contracts.”

Our process:

You will have an initial meeting with a Quantstamp business lead and lead auditor.

After receiving all necessary documentation and artifacts, we will assess the workload and provide a quote.

Once accepted, 3 - 4 of our auditors will independently review your code and documentation. They will check whether the code conforms to the provided specification. They will also perform automated analyses on the code, run the test suite, and measure test coverage.

Our auditors will then discuss any differences in their findings and come to consensus on solutions and recommendations.

Our audit lead and business lead will communicate with your team if we need any further information.
