The quickest way to start building on Hyperliquid with Quicknode is by sending a JSON-RPC request to your endpoint. In this quickstart, you’ll create an endpoint, copy its provider URL, and make your first request. Code samples are available in cURL as well as popular SDKs and programming languages.

HyperCore Access

The quickstart below uses HyperEVM (/evm path), which is available on all plans including free trial.

HyperCore services have additional requirements:

• /info endpoint: available on all plans; 71 of 73 methods are natively supported (see method availability)
• /hypercore JSON-RPC and WebSocket: requires Build plan or higher
• gRPC streaming: requires Build plan or higher

Envoyez votre première demande

Your endpoint is ready. Now, let's make your first call to the Hyperliquid blockchain. We’ll use the eth_blockNumber method, which returns the latest block number. Sélectionnez la langue ou SDK de votre choix SDK suivez les étapes ci-dessous pour envoyer votre première requête.

cURL

1

Vérifier l'installation de cURL

La plupart des systèmes basés sur *nix prennent en charge cURL dès leur installation. Ouvrez votre terminal et vérifiez la version de cURL en exécutant la commande ci-dessous :

curl --version

2

Envoyer une requête JSON-RPC

In your terminal, copy and paste the following cURL command to retrieve the latest block number:

curl -X POST YOUR_QUICKNODE_ENDPOINT_URL/ \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

3

Exemple de réponse

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x1234567"
}

SDK

1

Configurez votre projet

First, verify Node.js is installed with node --version. If not installed, download it from https://nodejs.org. Then create a new directory and initialize a Node.js project:

npm init -y

2

Installez le SDK

Install the SDK package:

npm install @quicknode/sdk

3

Create your main file

Create an index.js file for your code:

touch index.js

4

Add this code to your index.js file

Copy and paste this code into your index.js file:

const { Core } = require('@quicknode/sdk');

const main = async () => {
  const core = new Core({
    endpointUrl: 'YOUR_QUICKNODE_ENDPOINT_URL/',
  });

  const blockNumber = await core.client.request({
    method: 'eth_blockNumber',
  });

  console.log('Block number:', parseInt(blockNumber, 16));
};

main();
