Hashlock carried out a professional and comprehensive penetration test on the IvyFi project. The scope of the first audit included a detailed security assessment of IvyFi code to identify vulnerabilities and assess overall efficiency. The testing process involved a meticulous manual review, supplemented by advanced software-assisted techniques, to ensure thorough analysis and accuracy. This included frontend vulnerabilties, API testing and penetration testing of the staking service. The 2nd audit focused on penetration testing and vulnerabilities of the IvyFi server infrastructure and Key Management System.

Hashlock were professional and personable in their communication. Following the introductory meeting they provided an audit scope report and budget for the work of each audit. Their team provided excellent advice and took time to understand our platform and why it was structured the way it is. This resulted in a strong working relationship where honest and frank conversations could take place. Hashlocks professionalism and good humour alongside their technical detail meant that have greater confidence in the security of our services. We will definitely be keeping the relationship going as we seek to audit new services IvyFi has planned in the future.
