Summary

Current state of Zksync-era ; usage of proxy pattern is recommended by zksync-documentation

Vulnerability Details

zkSync Era is based on the zk-friendly VM. Thus, we offer a dedicated compiler responsible for transforming conventional Solidity and Vyper code into zkEVM bytecode.

While we have extensive test coverage to ensure EVM compatibility, issues may still appear. We will implement the patches for these in a timely manner.

To integrate a compiler bug fix, you need to recompile and upgrade your smart contract. We recommend using the Proxy pattern for a few months after your first deployment on zkSync Era, even if you plan to migrate to an immutable contract in the future.

Impact

Protocol stops working cause breaking changes on zkevm-opcodes
