What our Customers Say

From the beginning the Consensys Diligence team made a great effort to contribute to the security of the Aave Protocol, providing knowledge that helped us grow our awareness and security-focused culture. Their technology will be extremely helpful to move Aave forward. Their MythX technology was used in this project to verify the correctness of the Aave smart contract system

Working with the MythX team solidified our perspective on the effectiveness of fuzz testing, and strengthened the trust in the audit report Consensys Diligence led on our v3.0 release.
