Ledger Live Integrations

Official Ledger Developer Portal Guide

The Ledger Live Developer Portal offers an extensive framework and comprehensive documentation for developers looking to securely integrate their blockchain projects, wallets, and decentralized applications (dApps) with Ledger Live, the official app for Ledger hardware wallets. With millions of users relying on Ledger Live for managing their cryptocurrencies securely, integration fosters broad user exposure coupled with best-in-class security protections.

Why Integrate with Ledger Live?

Ledger Live acts as a critical hub for Ledger hardware wallet users, providing portfolio management, transaction signing, app discovery, and access to Ledger ecosystem services like swaps and exchanges. Integration into Ledger Live is a strategic advantage for developers who want to:

Reach a large, security-conscious user base actively managing crypto assets.
Leverage Ledger’s hardware-backed security infrastructure for transaction signing and account management.
Offer seamless user experiences by embedding dApps into Ledger Live’s Discover section or supporting native blockchain accounts.
Access Ledger’s SDKs, Wallet API, and developer tools that streamline secure integration workflows.
Comply with Ledger’s rigorous security standards and audit processes, building trustworthiness and user confidence.

Main Integration Paths

Ledger Live integrations fall into three main categories, each tailored to different developer goals and project scopes:

1. Accounts / Blockchain Integration

This path enables Ledger Live to natively support your blockchain’s accounts, displaying balances, transaction histories, and supporting operations like sending, receiving, and staking within Ledger Live’s Accounts section. Integrators implement a CoinModule/CoinConfig, provide blockchain discovery and RPC bridging, and coordinate with Ledger’s integration team for approval and publication.

2. Discover / Live Apps Integration

Leverage Ledger Live’s Discover tab by embedding your web-native decentralized application (dApp) as a Live App. Using Ledger’s Wallet API and Services Kit, your app can securely request device signatures and interact with the user’s Ledger device without exposing sensitive keys. This method is ideal for web apps that require secure signature flows and user consent inside Ledger Live.

3. Device Application Development

Some blockchains or features require applications residing on Ledger devices themselves. Developers create device-level apps written in C or Rust that enable custom transaction parsing, cryptographic operations, or blockchain protocols to run securely on Ledger hardware. The Developer Portal hosts build and test guides, submission processes, and coding resources for on-device app development.

Integration Checklist for Developers

Explore Documentation: Study the Ledger Developer Portal thoroughly, focusing on integration introductions, Wallet API specifications, and blockchain support guides.
Choose Your Integration Path: Decide between Blockchain integration, Live App, or Device app based on your project’s requirements.
Security First: Design all user flows to avoid exposing private keys, relying on Ledger’s secure signing model and hardware protections.
Developer Mode: Enable Developer mode in Ledger Live to test integrations locally (Settings → About → click version 10 times).
Testing: Conduct unit and end-to-end tests with Ledger devices, following Continuous Integration guidelines.
Preparation: Prepare all necessary documentation including installation instructions, privacy policies, and manifests.
Coordination: Work with the Ledger integrations team through formal intake and approval processes for blockchain integrations.

Developer Experience Tips

Focus on making transaction UX intuitive by clearly displaying transaction amounts, fees, and recipient information. Use Ledger Wallet API utilities to manage signature approval flows elegantly. Provide human-readable prompts during device confirmations. Test across both mobile and desktop Ledger Live clients to ensure robust device support.

Sample Code Snippets

// Node.js example illustrating a minimal Wallet API request endpoint
import express from 'express';
const app = express();

app.post('/wallet-api/request-sign', async (req, res) => {
const { txPayload } = req.body;
// Validate request, forward signing to Ledger Live/device securely
res.json({ status: 'ok', message: 'Request forwarded' });
});

app.listen(3000, () => console.log('Wallet API server running on :3000'));
