👷 Hardhat​

Hardhat is an Ethereum development environment for professionals. It facilitates performing frequent tasks, such as running tests, automatically checking code for mistakes or interacting with a smart contract. To get started, check out the tutorial created by the team!

It is recommended to use the following config in your hardhat.config.js file:

module.exports = {
  solidity: "0.8.24",
  networks: {
    etherlinkTestnet: {
      url: "https://node.ghostnet.etherlink.com",
      accounts: ["<YOUR_PRIVATE_KEY>"],
    }
  },
  etherscan: {
    apiKey: {
      etherlinkTestnet: "YOU_CAN_COPY_ME",
    },
    customChains: [
      {
        network: "etherlinkTestnet",
        chainId: 128123,
        urls: {
          apiURL: "https://testnet-explorer.etherlink.com/api",
          browserURL: "https://testnet-explorer.etherlink.com"
        }
      },
    ]
  },
};

Deploying and Verifying Contracts with Hardhat​

Hardhat offers great guides for deploying and verifying your contracts. Just make sure to set the network flag appropriately: --network etherlinkTestnet

🔥 Foundry​

Foundry is a fast, portable and modular toolkit for Ethereum application development written in Rust. It consists of various subpackages:

Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
Chisel: Fast, utilitarian, and verbose solidity REPL.

Deploying and Verifying Contracts with Foundry​

For the most up to date information on how to deploy and verify a smart contract, check out the guide provided by the Foundry team!

As a summary, you can run the following command:

forge create --rpc-url "https://node.ghostnet.etherlink.com" \
    --private-key "<YOUR_PRIVATE_KEY>" \
    --etherscan-api-key "YOU_CAN_COPY_ME" \
    --verify \
    src/YOUR_CONTRACT.sol:YOUR_CONTRACT --legacy
