Wallet API Client

☞ The renaming of “Ledger Live” to “Ledger Wallet” and “wallet” (in the hardware sense) to “signer” is still in progress. This page may contain legacy references that will be updated.

The Wallet API Client integrates decentralized applications (dApps), called Live Apps, into Ledger Wallet. Live Apps use the Ledger Wallet API to communicate with Ledger signers.

The library provides React hooks and utilities for crypto asset management apps, decentralized exchanges, and other blockchain projects. It also offers a framework-agnostic way to integrate Live Apps into Ledger Wallet.

💡

Migration from Platform SDK: If you are migrating from Platform SDK, see the migration guide.

Target audience

The Wallet API Client is for developers who build Live Apps to embed in Ledger Wallet. It enables communication between a Live App and the user’s Ledger signer through Ledger Wallet .

The library does not yet support other use cases, such as web apps connected to Ledger signers through the Ledger Extension . We expect to support more use cases in the future.

Overview

The Wallet API Client connects Live Apps, Ledger Wallet, and Ledger signers. Its modules, hooks, and utilities support account management, message signing, and transaction handling.
