Foundry的使用及配置

Foundry is a smart contract development toolchain.

With Foundry you can manage your dependencies, compile your project, run tests, deploy smart contracts, and interact with the chain from the command-line and via Solidity scripts.

Check out the Foundry Book to get started with using Foundry with Base.

Using Foundry with Base

Foundry supports Base out-of-the-box.

Just provide the Base RPC URL and Chain ID when deploying and verifying your contracts.

Hardhat的使用及配置

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.WALLET_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",

Truffle的配置及使用

Truffle is a comprehensive suite of tools for smart contract development.

You can use Truffle to quickly build, test, debug, and deploy your smart contracts to Base.

Using Truffle with Base

To configure Truffle to deploy smart contracts to Base:

Install Truffle by running the following command:
```
npm install -g truffle
```
Create a new Truffle project by running the following command:
```
truffle init
```

Update your project's truffle-config.js file by adding Base as a network:

const HDWalletProvider = require('@truffle/hdwallet-provider');

module.exports = {
  networks: {
    'base-mainnet': {
      provider: function () {
        return new HDWalletProvider('MNEMONIC', 'https://mainnet.base.org');
      },
    },
    'base-goerli': {
      provider: function () {
        return new HDWalletProvider('MNEMONIC', 'https://goerli.base.org');
      },
    },
    'base-local': {
      host: 'localhost',
      port: 8545,
      network_id: '*',
    },
  },
};

INFO

MNEMONIC is the mnemonic secret phrase of the account to use when deploying a contract.

Compile and deploy your smart contract by running the following command:
```
truffle migrate --network base-goerli
```
Note: When you're ready to compile and deploy to mainnet, simply change base-goerli to base-mainnet and rerun the command.

INFO
