Hyperevm API Quickstart

To use the Hyperevm API you’ll need to create a free Alchemy account first!

Checkout the Hyperliquid Alchemy Wallets Guide for enabling email and social login for user authentication, and the ability to sign and send transactions seamlessly.

Introduction

HyperEVM is a high-performance, Ethereum-compatible execution layer developed by HyperLiquid that enables smart contracts to run natively alongside its decentralized trading engine, combining low-latency performance with full EVM compatibility.

What is the Hyperevm API?

The Hyperevm API allows interaction with the Hyperevm 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.

$
# Begin with npm by following the npm documentation
>
# https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

2. Set Up Your Project

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

$
mkdir hyperevm-api-quickstart
>
cd hyperevm-api-quickstart
>
npm init --yes

This creates a new directory named hyperevm-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

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

1
const axios = require('axios');
2
3
const url = 'https://hyperliquid-mainnet.g.alchemy.com/v2/${your-api-key}';
4
5
const payload = {
6
  jsonrpc: '2.0',
7
  id: 1,
8
  method: 'eth_blockNumber',
9
  params: []
10
};
11
12
axios.post(url, payload)
13
  .then(response => {
14
    console.log('Latest Block:', response.data.result);
15
  })
16
  .catch(error => {
17
    console.error(error);
18
  });

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 Hyperevm network:

$
node index.js

You should see the latest block information from Hyperevm’s network outputted to your console:

$
Latest Block: 0x...

Next Steps
