Head of Smart Contracts Audits Department

“The role of professional auditors is to assist projects in making their products more secure and functional for users. Full understanding of your mistakes is the only way to prevent them in the future.”

Hacken zkSync crypto audits follow an industry-recognized smart contract code review and analysis methodology accepted by Cer.live, CoinGecko, and CoinMarketCap. Behind the scenes, Hacken auditors perform two separate line-to-line checks followed by the third check by a lead auditor. The double-blind method with a lead check gives the highest degree of confidence in vulnerability findings. Technically, auditing for zkSync is similar to any other EVM audit, because existing EVM-based projects work almost 1:1 in zkSync. Nevertheless, we account for the specifics of Layer 2 blockchain protocol to verify the risks of unsupported opcodes, pay attention to gas, and use zkSync-specific tools. We categorize all issues into four levels of severity, give recommendations appropriate for business context, conduct remediation checks to assess the quality of introduced bug fixes, provide the overall audit score based on documentation quality, code quality, architecture quality, and security.
