Monad API Quickstart

Introduction

Monad is a high-performance Ethereum-compatible L1. Monad materially advances the efficient frontier in the balance between decentralization and scalability.

Please note that we currently only support the Monad testnet

What is the Monad API?

The Monad API allows interaction with the Monad network through a set of JSON-RPC methods. Its design is familiar to developers who have worked with Ethereum's JSON-RPC APIs, making it intuitive and straightforward to use.

Getting Started Instructions

1. Choose a Package Manager (npm or yarn)

Select a package manager to manage your project's dependencies. Choose between npm and yarn based on your preference or project requirements.

2. Set Up Your Project

Open your terminal and execute the following commands to create and initialize your project:

mkdir monad-api-quickstart
cd monad-api-quickstart
npm init --yes

mkdir monad-api-quickstart
cd monad-api-quickstart
yarn init --yes

This creates a new directory named monad-api-quickstart and initializes a Node.js project within it.

3. Make Your First Request

Install Axios, a popular HTTP client, to make API requests:

npm install axios
# Or with yarn
# yarn add axios

Create an index.js file in your project directory and paste the following code:

const axios = require('axios');

const url = 'https://monad-testnet.g.alchemy.com/v2/${your-api-key}';

const payload = {
  jsonrpc: '2.0',
  id: 1,
  method: 'eth_blockNumber',
  params: []
};

axios.post(url, payload)
  .then(response => {
    console.log('Latest Block:', response.data.result);
  })
  .catch(error => {
    console.error(error);
  });

Remember to replace your-api-key with your actual Alchemy API key that you can get from your Alchemy dashboard.

4. Run Your Script

Execute your script to make a request to the Monad mainnet:

node index.js

You should see the latest block information from Monad's mainnet outputted to your console:

Latest Block: 0x...

Next Steps

Congratulations! You've made your first request to the Monad network. You can now explore the various JSON-RPC methods available on Monad and start building your dApps on this innovative platform.
