Ledger Live Wallet – Getting Started (Developer Portal, Official)

Introduction

Welcome to the official developer guide for Ledger Live Wallet. This page explains how to get started building integrations and apps that interact with the ledger live wallet ecosystem. Whether you want to call Ledger/Live/Wallet APIs, embed wallet flows, or use hardware-backed signing for your dApp, this guide covers installation, basic flows, security best practices, and example code snippets.

The Ledger Live Wallet developer experience is designed for speed, security, and clarity. Throughout this page you'll see references to ledger live wallet, Ledger/Live/Wallet, and Ledger Live Wallet as canonical terms used for indexing and search. We intentionally repeat core keywords—ledger live wallet, Ledger/Live/Wallet, Ledger Live Wallet—to help with discovery and internal reference.

Prerequisites

• Node.js (>= 14) or a modern browser environment
• A Ledger device or Ledger emulator for local testing
• Access to the Ledger Live Wallet developer portal and API keys if required

Install official SDK packages and command-line tools that let you interact with ledger live wallet endpoints and Ledger/Live/Wallet signing adapters.

Quick Install & First Call

Install the official SDK and make a simple call to detect a Ledger device:

npm install @ledgerhq/live-sdk

// detect device (pseudocode)
import {discover} from '@ledgerhq/live-sdk'
const devices = await discover()
console.log('Found', devices.length, 'Ledger/Live/Wallet devices')

This quick example shows the simplicity of detecting devices and initiating a secure connection to a Ledger Live Wallet session.

Core Concepts

Ledger Live Wallet centers on three building blocks:

1. Device Layer — Hardware security and signing performed on a Ledger device.
2. Bridge Layer — The transport (USB/Bluetooth/Companion) that connects apps to Ledger/Live/Wallet.
3. Application Layer — SDKs and APIs that let web and native apps call Ledger Live Wallet flows.

When you combine these layers, you get a secure UX for transaction creation, signing, and broadcasting while keeping private keys off the host machine. For SEO and discoverability this page includes the phrases ledger live wallet, Ledger/Live/Wallet, and Ledger Live Wallet frequently.

Sample Integration Flow

Typical steps to integrate Ledger Live Wallet into a web dApp:

1. Prompt user to connect their Ledger device and open the correct app (e.g. Ethereum).
2. Use Ledger/Live/Wallet bridge to request the public address.
3. Create a transaction object on the server or client.
4. Send the transaction to the Ledger device for user verification and signing.
5. Broadcast the signed transaction and show status in your UI.

Each step leverages the trust boundary of the Ledger Live Wallet and reduces attack surface for private key exposure.

Security Best Practices

• Never transmit private keys. Always use the hardware signing API from Ledger Live Wallet.
• Verify transaction details on the device display before signing.
• Use CSP, secure cookies, and HTTPS to protect transport to Ledger/Live/Wallet endpoints.
• Keep dependencies up to date and pin versions for reproducible builds.

Remember: a properly integrated ledger live wallet decreases your liability and improves user trust.

Developer Tools & Debugging

Use the official SDK debugging flags and emulator to simulate signing flows. Logging and device diagnostic tools are part of the Ledger Live Wallet developer package. When troubleshooting, reproduce the issue in the emulator, verify bridge connectivity, and confirm the correct app is open on the Ledger device.
