# QuickNode Hello World ## Overview Make your first blockchain queries: get block number, check ETH balance, read a smart contract. ## Prerequisites - Completed `quicknode-install-auth` with endpoint URL ## Instructions ### Step 1: Get Block Number ```typescript import { ethers } from 'ethers'; const provider = new ethers.JsonRpcProvider(process.env.QUICKNODE_ENDPOINT); const blockNumber = await provider.getBlockNumber(); console.log(`Current block: ${blockNumber}`); ``` ### Step 2: Check ETH Balance ```typescript const address = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // vitalik.eth const balance = await provider.getBalance(address); console.log(`Balance: ${ethers.formatEther(balance)} ETH`); ``` ### Step 3: Read Smart Contract (ERC-20 Token) ```typescript const usdcAddress = '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48'; const abi = ['function balanceOf(address) view returns (uint256)', 'function decimals() view returns (uint8)']; const usdc = new ethers.Contract(usdcAddress, abi, provider); const decimals = await usdc.decimals(); const balance = await usdc.balanceOf(address); console.log(`USDC balance: ${ethers.formatUnits(balance, decimals)}`); ``` ### Step 4: Get Transact

Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill quicknode-hello-world --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,630 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
