问题描述

为了对比数据方便，排除发起交易gas消耗引起的账户余额差别，会将hardhat test 脚本中设置发起交易，设置gasPrice：0

await contract.withdraw({from: accounts[15], gasPrice: 0})

执行hardhat test时报以下错误

Transaction gasPrice (0) is too low for the next block, which has a baseFeePerGas of 8

解决方案

hardhat-config.js中设置initialBaseFeePerGas: 0

 networks: {
        hardhat: {
            ...
            initialBaseFeePerGas: 0
        }
    }
