QuickNode Install Auth

Overview

Set up QuickNode blockchain RPC endpoints and install the QuickNode SDK or ethers.js for blockchain interactions.

Prerequisites

• QuickNode account at quicknode.com
• An endpoint created for your target chain (Ethereum, Solana, etc.)
• Node.js 18+

Instructions

Step 1: Create Endpoint

1. Go to quicknode.com > Dashboard > Create Endpoint
2. Select chain: Ethereum Mainnet (or testnet for development)
3. Copy the HTTP URL and WSS URL
   HTTP: https://xxx-yyy.quiknode.pro/TOKEN/
   WSS: wss://xxx-yyy.quiknode.pro/TOKEN/

Step 2: Install SDK

set -euo pipefail
npm install @quicknode/sdk viem
# Or with ethers.js
npm install ethers

Step 3: Configure Environment

# .env
QUICKNODE_ENDPOINT=https://xxx-yyy.quiknode.pro/YOUR_TOKEN/
QUICKNODE_WSS=wss://xxx-yyy.quiknode.pro/YOUR_TOKEN/

Step 4: Verify Connection (QuickNode SDK)

import { Core } from '@quicknode/sdk';

const core = new Core({ endpointUrl: process.env.QUICKNODE_ENDPOINT });
const blockNumber = await core.client.request({ method: 'eth_blockNumber' });
console.log(`Connected! Current block: ${parseInt(blockNumber, 16)}`);

Step 5: Verify Connection (ethers.js)

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider(process.env.QUICKNODE_ENDPOINT);
const block = await provider.getBlockNumber();
console.log(`Connected! Block: ${block}`);

Output

• QuickNode endpoint configured
• SDK installed and verified
• Successful RPC call confirming connectivity
