Overview

Ultra-low latency WebSocket streaming server for real-time Hyperliquid node data. Built for HFT applications with minimal overhead and sub-millisecond delivery.

Key Features

6 Real-Time Channels

Stream orderbook diffs, order statuses, TWAP updates, oracle data, and more directly from the node.

Subscribe / Unsubscribe

Dynamically manage your channel subscriptions over a single WebSocket connection.

HFT Optimized

Built with uvloop, orjson, 1ms polling intervals, and pre-allocated buffers for minimal latency.

O(1) Broadcast

Channel-to-client mapping ensures constant-time message delivery regardless of subscriber count.

How It Works

1. Create a Data Stream endpoint from the Data Streams dashboard.

2. Connect to your endpoint URL via WebSocket (WSS).

3. Send a subscribe message for each channel you want.

4. Receive real-time data as JSON messages.

Data Streams are ideal for trading bots, market makers, and any application that requires real-time on-chain event data with the lowest possible latency.
