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.

Years of Expertise
zkSync is a Layer 2 blockchain protocol built on zero knowledge rollup architecture designed for transferring Ether and ERC20 tokens to scale Ethereum.
As a zero knowledge blockchain, zkSync implements zkEVM, zkEVM is a virtual machine supporting zk rollup projects for Layer 2. zkEVM works like the standard EVM (Ethereum), which can permit a 1:1 communication between Ethereum and Layer 2 projects. A smart contract written for L1 Ethereum works without major tweaks to Layer 2 solutions.
The most common smart contract vulnerabilities are default visibilities, arithmetic over/underflows, entropy illusion, race conditions/front running, denial of service (dos), constructors with care, and tx.origin Authentication.
zkSync Smart Contract Audit is a cybersecurity solution based on smart contract code review and analysis that follows Hacken smart contract audit methodology and provides an audit report.
Hacken promotes a security-first mindset and a secure software development lifecycle. We encourage Web3 players to conduct internal audits and supplement internal results with an external review. Professional external code review verifies external findings and serves as a public confirmation of security.
Hacken has 5 years of experience in the cybersecurity market. We have conducted 1,200+ audits and have an international team of 100+ people. Hacken is a member of top blockchain organizations and a trusted partner of 180+ Web3 projects. Our leadership is public.
