What our clients say about us

"As we build blockchain experiences that thrive in the mainstream, alongside thousands of talented independent builders on Flow, Quantstamp is bringing to the ecosystem the high-quality security and code review their firm has long been recognized for. Quantstamp will no doubt be an important part of Flow's continued scaling and success."

Roham GharegozlouCEO at Dapper Labs

“Quantstamp's ability to quickly produce comprehensive and insightful audits has proven them to be an invaluable partner for our grantees. The importance of the extra layer of due diligence they provide can't be overstated.”

Richard Brown Former Head of Community Development at Maker

"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 initatives in the past, and working with Quantstamp was an obvious decision to make."

Vansa Chatikavanij CEO at OmiseGO

“Quantstamp ensured that our contracts met the highest standards of security through their excellent audit process. They worked hand in hand with our engineers to make sure our smart contracts were as safe as can be and their recommendations helped improve the quality of our code.”

Omri Ross Chief Blockchain Scientist, eToro

“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, Mainframe

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.
