Brokers building the securities UI in their Broker App from scratch combine WhaleCore SDK with Trading API.
- WhaleCore SDK is the UI-free data layer beneath Whale SDK. It provides market-data subscriptions, WebSocket connectivity, request signing, and token renewal.
- Trading API is a customer-scoped HTTP API for account, asset, trading, and related business capabilities.
WhaleCore SDK targets iOS, Android, and Web. iOS and Android are available; the WebAssembly version for Web is in development.
Note
WhaleCore SDK does not provide UI and does not replace Trading API. A custom client normally uses both.
Use Whale SDK instead when you want a complete, ready-made trading UI.
