将项目ID连接到多边形

Question

我做错了什么/丢失了什么？当尝试从https://infura.io/连接我的项目id时，我在运行后得到以下错误：

$  npx hardhat run scripts/deploy.js --network mumbai  

错误：

ProviderError:项目ID无权访问多边形l2

这是我的档案

require("@nomiclabs/hardhat-waffle");
require("dotenv").config();
const privateKey = process.env.PRIVATE_KEY;
const projectId = process.env.PROJECT_ID;

if (privateKey.error) {
  throw privateKey.error;
}

if (projectId.error) {
  throw projectId.error;
}

module.exports = {
  networks: {
    hardhat: {
      chainId: 1337,
    },
    mumbai: {
      url: `https://polygon-mumbai.infura.io/v3/${projectId}`,
      accounts: [privateKey],
    },
    mainnet: {
      url: `https://arbitrum-mainnet.infura.io/v3/${projectId}`,
      accounts: [privateKey],
    },
    matic: {
      url: "https://rpc-mainnet.maticvigil.com",
      accounts: [privateKey],
    },
  },
  solidity: "0.8.4",
};

Answer 1

实际上我弄明白了，原来我需要在我的帐户设置中启用多边形测试版，并为infura.io添加我的账单信息

Answer 2

炼金术- https://dashboard.alchemyapi.io/是与多边形网络交互的替代方案。不需要计费信息
