pragma solidity ^0.8.19;

contract HelloNexi {
    string public message;

    constructor(string memory _message) {
        message = _message;
    }
}

Initialize Using Hardhat

npx hardhat init

Compile the Contract

npx hardhat compile

Deploy Using a Hardhat Script

const { ethers } = require("hardhat");

async function main() {
    const HelloNexi = await ethers.getContractFactory("HelloNexi");
    const contract = await HelloNexi.deploy("Hello, NEXI!");
    console.log("Deployed at:", contract.address);
}

main();

Run the Deployment

npx hardhat run scripts/deploy.js --network nexi
