👷 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: "",
accounts: ["<YOUR_PRIVATE_KEY>"],
etherscan: {
apiKey: {
etherlinkTestnet: "YOU_CAN_COPY_ME",
customChains: [
network: "etherlinkTestnet",
chainId: 128123,
urls: {
apiURL: "",
browserURL: ""
