Deploy a smart contract on Rome

Walkthrough to deploy a “Hello World” contract using MetaMask and Remix, and a video link.

This guide provides step-by-step instructions for deploying a smart contract on the Rome EVM network using MetaMask and Remix IDE.

Prerequisites

• MetaMask: Ensure the MetaMask browser extension is installed and configured.

• Remix IDE: We will be utilizing Remix for deploying the smart contract directly.

• Foundational Knowledge: A basic understanding of smart contracts and Ethereum-compatible networks will be helpful to follow along.

Set up Rome Network in Metamask

1. Open MetaMask and click on the network dropdown at the top.

2. Select "Add a custom network".

3. Fill in the Rome network details.

4. Click "Save" and switch to the Rome network.

Obtain Rome Tokens for Gas Fees

1. Visit the Rome network faucet: https://rome.testnet.romeprotocol.xyz/request_airdrop.

2. Request testnet tokens for your MetaMask address.

3. Wait for the tokens to appear in your MetaMask wallet.

Write your Smart Contract

1. Open Remix IDE in your browser.

2. Create a new file or open an existing one with your smart contract code.

3. For this example, we'll use a simple "Hello World" contract using Solidity

// SPDX-License-Identifier: MIT
// compiler version must be greater than or equal to 0.8.26 and less than 0.9.0
pragma solidity ^0.8.26;
contract HelloWorld {
    string public greet = "Hello World!";
}

1. Compile the smart contract.

2. In Remix IDE, go to the "Deploy & Run Transactions" tab.

3. In the "Environment" dropdown, select "Injected Provider - MetaMask". Ensure MetaMask

   is connected to the Rome network.

4. Click Deploy.

5. MetaMask will prompt you to confirm the transaction. Review the details and approve it. Wait for the transaction to be confirmed on the Rome network.

6. Once the transaction is confirmed, Remix will display the deployed contract address, somewhat like this.

Voila 🎉! You have successfully deployed your first smart contract on the Rome EVM network.

To view the transaction details, visit the Rome network block explorer https://rome.testnet.romeprotocol.xyz:1000 and search for your contract address or transaction hash.
