      Does a passed audit mean that the project is safe?

      A finalized audit, unfortunately, does not guarantee project’s safety. Before investing it’s good to recheck the existing issues and vulnerabilities, presented in the audit report. It also helps if the project’s lp is locked, and the project’s team is known publicly or has passed a KYC by a tire one security company.

      How to read a HashEx audit report?

      HashEx report consists of several blocks: aside from disclaimer, HashEx reviews submitted contracts, outlining the main issues in each contract. Auditors state the issue and present a short description with the potential danger of said issue. Note that there is a table of contents, in this case, audited contracts. It’s important to make sure that all the contracts have indeed been audited and that a client didn’t add new ones that haven’t been reviewed.

      What separates a HashEx audit from any other one?

      HashEx team has a rich background in DeFi security. The company itself has over 4 years of experience in DeFi security and has performed over 500 audits. Our team of auditors has a vast library of known issues and thanks to manual reviews, they have the ability to find even minor errors. The reviews are performed first by an automated tool, then by two separate teams. This process is aimed at eliminating the possibility of missed vulnerabilities.
