On top of the first audit report by OpenZeppelin, the second audit report from Secure3 has revealed that innovative Ethereum scaling solution zkSync 2.0 is right on track in the race to become the industry’s first EVM-compatible zero-knowledge rollup. Please see zkSync Layer 1 Audit report for the full report.

After a three-week rigorous and meticulous audit contest, Secure3 concluded that Matter Labs have already fixed all findings, and zkSync 2.0’s Layer-1 building blocks have zero critical issues so far.

According to the specific features of zkSync’s L1 implementation, Secure3 has tailor-made an audit contest with senior auditors who have L2 audit experience and researchers who have prior research on L2 and related cryptography for Matter Labs. Though the project is technically complex, Secure3 team were impressed by the completeness, responsiveness and consistency of the Matter Labs and its engineering and security team. After extensive audits via competition and cross-validation, Secure3 team concluded that no critical issues were found in zkSync’s code.

zkSync 2.0 is a permissionless, end-to-end ZK Rollup that supports generalized EVM compatibility for the Ethereum blockchain. The primary benefit of zkSync 2.0 is that developers building EVM DApps can port to zkSync 2.0 effortlessly, with low gas fees and high transaction speeds — all without compromising security or decentralization. The alpha version of zkSync 2.0 was released on October 28, 2022, as part of a three-step process of bringing the technology fully into production.

“Safety and security is the most critical aspect of our work because it makes everything else worth building.” says Anton Astafiev, Matter Labs’ Head of Security. “We welcome Secure3’s audit contest as we continue inviting projects to deploy on zkSync 2.0 ahead of our Fair Onboarding Alpha in Q1 2023. When we open our layer 2 to end users at our Fair Launch Alpha in Q2 2023, we’re determined for it to be as secure as possible.”

About Matter Labs

Matter Labs is the team behind zkSync, an EVM-compatible ZK-rollup which scales Ethereum’s values and technology without degrading the blockchain’s decentralization or security. This technology enables anyone to easily and seamlessly port their projects from older EVM-compatible solutions to zkSync 2.0 and holds the promise of being the endgame for scaling Ethereum, unlocking millions of use cases and creating an ecosystem that could benefit billions of people by enabling everyone to achieve personal sovereignty.
