Introduction to Ledger Live Integrations
Ledger Live provides a comprehensive platform for both users and developers to manage cryptocurrency securely. The Ledger Developer Portal empowers developers to integrate blockchains, Live Apps, and services directly into Ledger Live, leveraging advanced security models and a trusted UI/UX environment.
From adding native blockchain support to embedding web-based Live Apps in the Discover section, Ledger Live integrations extend the platform’s functionality and user reach while maintaining Ledger’s signature security standards.
Main Pillars of Integration
1. Blockchain / Account Integration
To provide native support for a blockchain, developers create modules implementing CoinConfig and CoinModule interfaces. This enables users to manage accounts, view balances, send/receive assets, and even stake tokens within Ledger Live.
Process highlights include:
- Providing discovery layers to locate user accounts
- Implementing RPC bridging for blockchain communication
- Collaborating with the Ledger team through formal agreements and intake forms
This integration offers the deepest user experience by fully embedding blockchain functionality into Ledger Live’s interface.
2. Discover & Live Apps Integration
Live Apps are web applications surfaced inside Ledger Live’s Discover tab. Using the Wallet API and Ledger Services Kit, developers build secure dApps, swap platforms, and utilities that interact with the user’s Ledger device for actions like secure transaction signing.
This path enables web-native experiences without exposing private keys and runs within Ledger Live’s controlled environment.
3. Device Application (On-Device Apps)
Device apps running directly on Ledger hardware provide deep integration for protocols requiring specialized cryptography or transaction parsing.
Developers must use supported languages like C or Rust and follow official build, test, and submission workflows to ensure hardware functionality and security.
Developer Resources & Best Practices
The Ledger Developer Portal offers extensive documentation and tools to help developers onboard quickly and securely:
- Ledger Live Integrations Docs: Detailed guides to navigate different integration types.
- Wallet API and Services Kit: SDKs and API references for Live Apps development.
- Developer Mode in Ledger Live: Enables local testing and debugging functionalities.
- Security Guidelines: Enforce flows that never expose sensitive seed material and align with Ledger’s signing model.
- Testing and CI: Comprehensive unit and end-to-end testing practices with real devices.
- Submission Checklist: Requirements for documentation, installation, manifests, and privacy policies.
User Experience & UI Considerations
Ledger emphasizes simplicity and clarity in user interfaces. Key recommendations include:
- Clear transaction details: show amounts, fees, and recipient information unambiguously.
- Use Wallet API hooks to request device approvals with streamlined UX flows.
- Display human-friendly instructions during on-device signature requests rather than raw hex data.
- Ensure cross-platform compatibility, both mobile and desktop Ledger Live versions.
Example Code Snippets for Developers
Here are simple snippets illustrating common developer tasks:
Importing a Local Live App Manifest (Developer Mode)
{
"manifest_version": "1.0",
"name": "Example Live App",
"start_url": "https://your-liveapp.example.com/",
"permissions": ["ledger"],
"icons": ["/icon-192.png"]
}
Minimal Wallet API Server Endpoint (Node.js)
import express from "express";
const app = express();
app.post("/wallet-api/request-sign", async (req, res) => {
// Validate request, session and origin
const { txPayload } = req.body;
// Forward signed transaction to Ledger Live
res.json({ status: "ok", message: "Request forwarded" });
});
app.listen(3000, () => console.log("Wallet API server running on :3000"));
