Ledger Live Integrations – Ledger Developer Portal

Guide to integrating with Ledger Live: APIs, SDKs, UX patterns, and best practices for developers.

Overview

Audience: Developers • Integrators • Product managers

Ledger Live is the user-facing application connecting end users to their hardware wallets and to a broad ecosystem of apps and services. This presentation explains integration points — from native SDKs to webhooks and context-aware UX — so you can design secure, delightful experiences for users who rely on Ledger devices.

Integration types (h3)

1. Ledger Live SDK & APIs (h4)

Build direct integrations using Ledger’s SDKs and public APIs. Typical use cases: balance sync, transaction construction, and signature orchestration with Ledger hardware devices. 

// Example (pseudo)
const tx = Ledger.constructPayment({to, amount});
const signed = await Ledger.signWithDevice(tx);
await Ledger.broadcast(signed);

2. Web integrations (h4)

Use the Ledger Live protocol via deep links and browser SDKs to open the Ledger Live app from your web product, allowing users to confirm actions on-device without exposing private keys.

3. Mobile & Desktop (h4)

Integrate with both Ledger Live Desktop and Mobile clients via the officially supported entry points. Respect platform-specific UX patterns for background connections and Bluetooth pairing.

Security best practices (h3)

  • Never transmit private keys — use Ledger’s signing endpoints which require user confirmation on device.
  • Validate all transaction parameters client-side and server-side.
  • Use TLS 1.2+ for all endpoints and rotate API keys regularly.
  • Provide clear transaction metadata so users can easily verify actions on their Ledger device.

UX patterns & flows (h3)

Connect flow (h4)

  1. Prompt user to connect their Ledger device (USB or Bluetooth).
  2. Open Ledger Live (deep link) to request account access.
  3. Show a clear modal explaining what will be signed and why.
  4. Wait for on-device user confirmation, then continue the flow.

Transaction review (h4)

When requesting signatures, structure the review page to show only critical fields first (recipient, amount, network fee) and supply an expandable section for advanced metadata. This reduces cognitive load when users verify on-device.

Developer tools & debugging (h3)

Ensure reproducible test setups: emulators, testnets, and sample wallets. Use verbose logging for the handshake and signature steps, and always provide a recovery path if the device becomes unresponsive.

Tip (h5)

Instrument timing metrics for connect, sign, and broadcast stages to analyze friction points.

FAQ

Q: What is the recommended way to request a signature from Ledger Live?
A: Use Ledger’s signing SDK or open a Ledger Live deep link that triggers the sign request; always include structured metadata so the user can verify on-device.
Q: Can I perform background transactions without user interaction?
A: No — private key operations always require explicit user confirmation on the Ledger device to protect against silent theft.
Q: Which environments should I test integrations on?
A: Use both Ledger Live Desktop and Mobile builds, plus testnets (e.g., Ropsten, Goerli for Ethereum-based flows) and emulator tools where available.
Q: How do I handle firmware or app version mismatches?
A: Detect device firmware and app versions during handshake and surface a clear upgrade instruction modal when a minimum version is required.
Q: Where can I find SDK documentation and developer resources?
A: See the list of official Ledger resources in the sidebar for direct links to SDKs, docs, and support.
