Leading Blockchain Projects Work With Quantstamp

“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 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’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.”

Noah Thorp Vice President of Engineering, Sharespost

“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.

Quantstamp Verified security certificate

Keep your funds safe. Protect your reputation. Add the value of trust to your smart contract project.

Our quotes and turnaround times vary according to the codebase’s length and complexity.

Send an email to audit@quantstamp.com with details about your project’s website, links to your source code, and documentation to receive a quote.

We provide confidential initial reports, web hosted public final certificates for easy sharing with stakeholders and also formally written letters for compliance departments to confirm the results of a security audit.
