How do you configure different networks in Hardhat?

beginner

Re-explain

Networks are configured in the hardhat.config.js file under the networks object:

module.exports = {
  networks: {
    localhost: {
      url: "http://127.0.0.1:8545"
    },
    goerli: {
      url: "https://goerli.infura.io/v3/YOUR_INFURA_KEY",
      accounts: [PRIVATE_KEY]
    },
    mainnet: {
      url: "https://mainnet.infura.io/v3/YOUR_INFURA_KEY",
      accounts: [PRIVATE_KEY],
      gasPrice: 20000000000
    }
  }
};

You can then deploy to specific networks using: npx hardhat run scripts/deploy.js --network goerli
