概覽
Quicknode SQL Explorer lets you query on-chain data with standard SQL — no indexers, no subgraphs, just a REST API and your API key. This sample app demonstrates how to integrate SQL Explorer into a frontend, shipping with 40+ ready-to-run queries against Hyperliquid on-chain data with table and chart views so you can see results immediately.
建築
Browser (Next.js frontend)
-> /api/query (server-side proxy route)
-> Quicknode SQL Explorer REST API
-> Returns structured rows
-> Table view + Chart visualization
特色
- 40+ pre-built queries organized by category: Trading, Fills, Orders, Funding, Markets, Portfolio & Positions, Staking & Rewards
- Parameterized queries with dynamic inputs for wallet addresses, validators, and coin symbols
- Dual result views — sortable/paginated tables and bar/line/area/pie charts
- Code snippets — copy-paste ready code in SQL, curl, TypeScript, and Python for every query
- Use-case pages — deeper implementations for validator rewards, wallet activity, and liquidations
- Server-side API proxy — keeps your API key secure on the backend
先決條件
- Node.js 20+
- A Quicknode account with an API key that has the SQL application enabled (create one here)

開始使用
1. Clone the repository
git clone https://github.com/quiknode-labs/qn-guide-examples.git
cd sample-dapps/sql-explorer-cookbook
2. Install dependencies
npm install
3. Configure environment variables
cp .env.example .env.local
Edit .env.local with your Quicknode API key and endpoint details.
4. Start the development server
npm run dev
Open http://localhost:3000 to start exploring queries.
API 端點
POST /api/query— Server-side proxy that forwards SQL queries to the Quicknode SQL Explorer REST API and returns results

用法
- Pick a starting point — Choose one of the 3 sample use cases (Wallet Activity, Validator Rewards, Liquidations) from the home page, or explore all 40+ pre-built queries in the explorer.
- Run a query — Click run to execute the SQL against Hyperliquid on-chain data. Results appear as a sortable table or chart.
- Customize parameters — Some queries accept dynamic inputs like wallet addresses, validators, or coin symbols. Click Try sample to populate example values, then re-run.
- Copy code snippets — Each query provides copy-paste ready code in SQL, curl, TypeScript, and Python.
Adding Custom Queries
Add entries to src/data/queries.ts:
{
id: "my-query",
title: "My Custom Query",
description: "Description of what this query does",
category: "Trading",
sql: `SELECT * FROM hyperliquid_trades LIMIT 10`,
chartConfig: { // optional
type: "bar",
xKey: "coin",
yKeys: ["volume_usd"],
},
}
