# QuickNode SDK Patterns ## Overview Production-ready patterns for blockchain development with QuickNode: provider singletons, retry logic, batch RPC calls, and multi-chain support. ## Prerequisites - Completed `quicknode-install-auth` - ethers.js or @quicknode/sdk installed ## Instructions ### Step 1: Provider Singleton ```typescript import { ethers } from 'ethers'; let _provider: ethers.JsonRpcProvider | null = null; export function getProvider(): ethers.JsonRpcProvider { if (!_provider) { _provider = new ethers.JsonRpcProvider(process.env.QUICKNODE_ENDPOINT, undefined, { staticNetwork: true, // Skip chainId lookup on every call batchMaxCount: 10, // Enable batch RPC }); } return _provider; } ``` ### Step 2: Retry Wrapper with Backoff ```typescript async function withRetry<T>(fn: () => Promise<T>, maxRetries = 3): Promise<T> { for (let attempt = 0; attempt <= maxRetries; attempt++) { try { return await fn(); } catch (err: any) { const isRetryable = err.code === 'SERVER_ERROR' || err.code === 'TIMEOUT' || err.status === 429; if (!isRetryable || attempt === maxRetries) throw err; const delay = Math.min(1000 * Math.pow(2, attempt), 10000); await new Promise(r => setTimeout(r, delay)

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill quicknode-sdk-patterns --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.
