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 Sepolia testnet
   "base-sepolia": {
     url: "https://sepolia.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",
