# Welcome to the Wallet API Client documentation

This library is exclusively designed to facilitate the seamless integration of decentralized applications (dApps), termed as Live Apps, within . It provides a streamlined way for Live Apps to communicate with  via the  API.

Whether you are developing a crypto asset management app, a decentralized exchange, or any other blockchain project, this library is equipped with a set of React hooks and utilities to ensure a secure and efficient user experience.

This library serves as a cornerstone for integrating applications within , dubbed as Live Apps, in a framework-agnostic manner. By leveraging the  API Client, your Live App can interact with  through .

> **Note:** **Migration from Platform SDK:** If you are migrating from Platform SDK,
> please refer to [this section](./appendix/migration-guide) that will guide you
> through the process.

## Target Audience

The Wallet API Client is tailored for developers seeking to build Live Apps for embedding within . It ensures smooth communication between the Live App and the user’s  through [Ledger Wallet](https://www.ledger.com/ledger-live).

We expect to widen the scope of the library in the future to support other use cases as well such as web apps connected to Ledger wallets though the [Ledger Extension](https://www.ledger.com/ledger-extension), but this is not yet supported.
