Overzicht
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.
Architectuur
Browser (Next.js frontend)
-> /api/query (server-side proxy route)
-> Quicknode SQL Explorer REST API
-> Returns structured rows
-> Table view + Chart visualization
Kenmerken
- 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
Vereisten
- Node.js 20+
- A Quicknode account with an API key that has the SQL application enabled (create one here)

Voorbeeld
Gebruik
- 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

{
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"],
},
}
