QuickNode Install Auth Skill

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

Error Handling

| Error | Cause | Solution | |-------|-------|----------| | 401 Unauthorized | Invalid token in URL | Verify endpoint URL from Dashboard | | ECONNREFUSED | Wrong endpoint URL | Check HTTPS URL format | | eth method not found | Add-on required | Enable add-on in QuickNode Dashboard |
