Quick Start

Deploy Your First Contract

hardhat.config.js

module.exports = {
  solidity: "0.8.19",
  networks: {
    nera: {
      url: "https://rpc.nerachain.io",
      chainId: 587,
      accounts: [process.env.PRIVATE_KEY],
      gasPrice: 1000000000 // 1 gwei
    }
  }
};

deploy.js

const hre = require("hardhat");

async function main() {
  const Contract = await hre.ethers.getContractFactory("MyContract");
  const contract = await Contract.deploy();
  await contract.deployed();
  console.log("Deployed to:", contract.address);
