概要

This sample app enables real-time tracking of trading orders on Hyperliquid Core (L1). It leverages Quicknode Streams + Key-Value Store (KV Store) for intelligent, dynamic filtering without requiring stream restarts. Monitor whale traders, track order statuses, and receive live updates through a modern UI.

建築

Hyperliquid Core (L1)
-> Quicknode Streams + KV
-> POST /api/webhook/streams (signature verified)
-> OrderLog upsert + SSE emit
-> Live UI order feed

特長


  • Real-time address filtering via KV Store lists
  • Dynamic status filtering (open, filled, cancelled, rejected, triggered)
  • Blockchain-native filtering at the stream level
  • Server-Sent Events (SSE) for live UI updates
  • Quicknode Streams setup scripts (create + activate)
  • Bulk add trader addresses
  • Webhook signature verification and timestamp checks
  • ENS resolution for Ethereum addresses (optional)
  • Prisma + SQLite local storage

前提条件


  • Node.js 20+ and a package manager (pnpm, yarn, npm).
  • Quicknodeアカウント with Streams and KV Store access: Create an account, and get your Admin API key ~のために QN_API_KEY.
  • Public webhook URL: Use a tunnel like ngrok or deploy the app so APP_URL is reachable by Quicknode.
  • Optional: Ethereum mainnet RPC endpoint for ENS name resolution (QN_EVM_ENDPOINT).

プロジェクトの構成

filters/
hl-orders-filter.js # Quicknode Streams filter (HyperCore)
scripts/
setup-streams.ts # Creates KV lists + stream (paused)
activate-streams.ts # Activates stream by id
src/
app/api/ # API routes (webhooks, users, SSE)
lib/ # Quicknode, webhook, SSE helpers
types/ # TypeScript definitions
prisma/
schema.prisma # SQLite schema

環境変数

コピー .env.example ~へ .env and fill in:

QN_API_KEY=""                  # Quicknode API key with Streams + KV permissions
QN_STREAM_SECURITY_TOKEN="" # Stream security token (from setup script)
APP_URL="http://localhost:3000" # Public app URL (ngrok for local webhooks)
DATABASE_URL="file:./dev.db" # SQLite DB
QN_EVM_ENDPOINT="" # Optional: Ethereum RPC for ENS resolution
ADMIN_API_KEY="" # Optional for local dev, required for production

注:

  • QN_STREAM_SECURITY_TOKEN is returned by setup:streams.
  • APP_URL must be reachable by Quicknode (use ngrok or a deployed URL).
  • Ensure your API key has both Streams and KV Store permissions enabled.

はじめに

1. Install dependencies

pnpm install
# npm install
# yarn install

2. Create your env file

cp .env.example .env

3. Add required variables

記入してください .env (see 前提条件). For local webhooks, expose your app with ngrok and copy the HTTPS URL into APP_URL:

ngrok http 3000

4. Initialize the database

pnpm prisma migrate dev --name hypercore-order-monitor
pnpm db:seed

The seed script creates status filters (enabling open, filled, triggered by default) and adds a sample trader address.

5. Create Quicknode Streams + KV lists

pnpm run setup:streams

Copy the printed security token into .env (QN_STREAM_SECURITY_TOKEN).

6. Start the app

pnpm dev

7. Activate the stream

pnpm run activate:streams

開く http://localhost:3000, add trader addresses, and you should see live order events as streams deliver webhooks.

Database

SQLite is used by default. Prisma schema is in prisma/schema.prisma.

Common commands:

pnpm prisma migrate dev --name <name>
pnpm db:seed
pnpm prisma studio

Webhook Security and Payload


  • Endpoint: POST /api/webhook/streams
  • Headers required: x-qn-nonce, x-qn-timestamp, x-qn-signature
  • Payload can be gzip compressed; the handler auto-detects content-encoding: gzip
  • Signature verification uses QN_STREAM_SECURITY_TOKEN

APIエンドポイント


Public endpoints:

  • GET /api/health - health check
  • GET /api/users - list monitored traders
  • GET /api/statuses - list status filters
  • POST /api/webhook/streams - Quicknode Streams webhook
  • GET /api/sse - SSE stream of order events

Protected endpoints (require Authorization: Bearer <ADMIN_API_KEY>):

  • POST /api/users - add a trader
  • POST /api/users/bulk - bulk add traders (50 address limit)
  • PATCH /api/users?id=... - update trader
  • DELETE /api/users?id=... - remove trader
  • GET /api/orders - list orders with filters
  • PATCH /api/statuses - update enabled statuses
  • POST /api/statuses/reset - reset to defaults

Synchronization Scripts


  • pnpm run sync:statuses - Reconciles KV status list with database
  • pnpm run sync:users - Reconciles KV user list with database
  • pnpm run reset:kv - Deletes HyperCore KV lists
