我遇到了同样的错误,我想出了两个解决方案:
在您的hardhat.config.js网络中添加手动气体限制:
your network: {
url: `https://rinkeby.infura.io/v3/${process.env.PROJECT_ID}`,
accounts: [privateKey],
gas: 2100000,
gasPrice: 8000000000,
}

在您的文件中,使用您的网络index.js而不是 中的 mainnet :Web3Modal
const web3Modal = new Web3Modal({
network: "your network name",
cacheProvider: true,
