 - Use upgradable contracts: The zkSync Era is still in the early stages of development, and although the team has conducted extensive testing to ensure EVM compatibility, issues may still arise. Therefore, when deploying contracts, you should try to use upgradable proxy contracts to deal with possible problems. If you don’t understand proxy contracts/upgradeable contracts, you can refer to the WTF Solidity tutorial [Lecture 48](https://github.com/AmazingAng/WTF-Solidity/blob/main/48_TransparentProxy/readme.md) and [Lecture 49 ](https://github.com/AmazingAng/WTF-Solidity/blob/main/49_UUPS/readme.md).
 
-- Do not rely on EVM's gas logic: zkSync has its own set of gas logic, which is different from L1. For example, it will consider the gas consumption when data is published in L1. For details, please refer to [Document](https://docs.zksync.io/zk -stack/concepts/fee-mechanism.html).
