# 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 ```text 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 ```bash set -euo pipefail npm install @quicknode/sdk viem # Or with ethers.js npm install ethers ``` ### Step 3: Configure Environment ```bash # .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) ```typescript 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) ```typescript 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 con...
