What Smart Contract Security Audit is?

Hackers and intruders can find vulnerabilities even in seemingly perfect code. Periodic audits in this case are the best solution to the problem. Paying attention to weak points during the audit is able anticipate illegal actions and fix bugs in a timely manner.

  • Just a small part of actions we perform during the audit consists of static analysis of the code, smart contract audit using trusted tools, tests of all the vulnerabilities have been found, efficiency and optimization checks and drawing up a detailed audit report.

  • Following the recommendations of the audit report allows to get the best possible positive security score and become more attractive to the customers. Regular audits let the smart contract become more safe and optimized.

  • Self-audits are important as well but these types of checks are less full and deep than professional smart contract security audit. From our side we offer all the experience and professionalism we have and provide high level audit services.

      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.
