hardhat-contract-sizer

hardhat-gas-reporter
Although this plugin works out of the box, ZKsync Era has a different fee model than Ethereum. Users should consider this when analysing the report generated by this plugin.
In addition, make sure to read about local testing.
hardhat-preprocessor
This plugin enables the pre-processing of contract source code prior to compilation.
--no-compile flag: yarn hardhat verify --no-compile.nomicfoundation/hardhat-network-helpers
This plugin adds new methods that interact with the Hardhat network used for testing.
In version 1.0.12, hardhat-network-helpers introduced support for both In-Memory Node and Dockerized setups, allowing methods
such as loadFixture to be utilized in test files.
hardhat_impersonateAccount or hardhat_setBalance are supported, other RPC methods might not be supported by the In-Memory Node.
Please check the list of suported APIs.Unsupported plugins
nomiclabs/hardhat-etherscan
This plugin has been deprecated in favor of nomicfoundation/hardhat-verify. The ZKsync plugins for smart contract verification are built
on top of nomicfoundation/hardhat-verify, making migration to it necessary.
