Hyperliquid WebSocket Streaming

Hyperliquid runs on HyperBFT, and its native interface is WebSocket pub/sub. Supanode exposes it as one flat tier covering the live orderbook, trades, and account events, with unlimited bandwidth and no per-message fees.

Yes — up to 48 hours, no card required. Message Supanode on Telegram, say what you want to test, and the trial is activated for the WebSocket Streaming tier.

Your WebSocket endpoint is provisioned for you over Telegram when you subscribe. Once provisioned, you connect over standard WebSocket and subscribe to the streams you need — orderbook, trades, account events.

Bandwidth is unlimited and unmetered — no per-message or per-byte fees, and no credit math. The flat monthly tier covers the orderbook, trades, and account-event streams at whatever volume the market produces.

WebSocket delivers live events from the moment you subscribe. For history, the Supanode Hyperliquid Indexer holds every fill, funding payment, and TWAP with nanosecond timestamps, queryable over ClickHouse SQL. The two pair naturally: stream live, backtest on the warehouse.

Any standard WebSocket client — Python, Node.js, Rust, Go, even a browser. There is no proprietary SDK to install: the interface is plain pub/sub JSON, so the library you already use is the right one.
