# Frontend Integrations

Yearn uses a JavaScript SDK for formatting protocol data and generating transactions for reading/writing protocol data. Yearn SDK integrates several components, both onchain and offchain.

[The repository here](https://github.com/turtlemoji/yearn-sdk-examples) contains a live preview and example usage of the Yearn SDK. Explore this codebase to learn how to start interacting with the Yearn protocol in your own app.
