Hardhat is an Ethereum development environment for flexible, extensible, and fast smart contract development.

You can use Hardhat to edit, compile, debug, and deploy your smart contracts to Base.

Using Hardhat with Base

To configure Hardhat to deploy smart contracts to Base, update your project’s hardhat.config.ts file by adding Base as a network:

networks: {
   // for mainnet
   "base-mainnet": {
     url: 'https://mainnet.base.org',
     accounts: [process.env.PRIVATE_KEY as string],
     gasPrice: 1000000000,
   },
   // for testnet
   "base-goerli": {
     url: "https://goerli.base.org",
     accounts: [process.env.PRIVATE_KEY as string]
     gasPrice: 1000000000,
   },
   // for local dev environment
   "base-local": {
     url: "http://localhost:8545",
     accounts: [process.env.PRIVATE_KEY as string]
     gasPrice: 1000000000,
   },
 },
 defaultNetwork: "base-local",
