What is Sailfish?

Sailfish provides real-time & historic market data across Solana, Ethereum, Binance Chain, Hyperliquid, Polymarket & Kalshi.

The market data can be used for market analysis, algorithming trading and anything else you can imagine.

Sailfish Components

Sailfish Websocket

Low latency, filterable market data streaming.

Sailfish API

High fidelity API to retrieve historic data. In short (almost) all the data you reveive via the Websocket streaming is indexed and made available via the API.

Sailfish SDK

An open source typescript SDK that allows developers to easily get started writing applications that use Sailfish. The SDK is a good start for those who are interesting in writing their first trading bot or just exploring the Sailfish resources.
