Ledger® Live Wallet – Getting Started™ Developer Portal

A practical onboarding guide for developers integrating Ledger Live Wallet features, security patterns, APIs, and distribution tips.

Overview

Welcome to the Ledger Live Wallet Developer Portal add-on. This resource is crafted for engineers, product managers, and security teams building integrations that interact with Ledger hardware and Ledger Live. It covers high-level architecture, recommended SDKs, UX patterns, signing flows, and essential security hygiene. The goal is to help you ship a safe, smooth, and compliant wallet experience while giving your users the benefits of secure key management.

Quickstart: How it fits together

Typical integrations connect your dApp or service to the Ledger Live Wallet through a combination of Producer libraries and WalletConnect or bespoke transport layers. You will often:

  • Use the Ledger SDK for device-aware signing and app management.
  • Expose a lightweight UX where users confirm transaction details on their device.
  • Respect deterministic derivation paths, network-specific parameters, and replay protections.

// Example pseudo-flow:
1. Connect to Ledger device via WebUSB / BLE / HID
2. Query account and public keys
3. Create unsigned transaction
4. Send transaction to device for user confirmation and signature
5. Broadcast signed transaction to network

SDKs, protocols, and recommended libraries

Use the official SDKs for your platform when possible. Ledger provides device libraries for JavaScript, Rust, and mobile platforms that make it simple to manage transports and secure signing. If you use WalletConnect to mediate between a mobile wallet and a dApp, make sure you implement proper session handling and expiry. When choosing a library, prefer maintained packages with clear security audits and active maintainers.

Security best practices

Security is the central value of the Ledger ecosystem. Always:

  • Never request or store private keys or seed phrases on your servers.
  • Use secure transport (HTTPS/TLS) for all backend calls.
  • Implement anti-replay protections and validate all signatures server-side before broadcast.
  • Provide clear UI messages that show exactly what the user is approving on-device.

If you're handling custody flows, consider layered approvals, rate limits, and hardware-enforced multi-sig where appropriate. For enterprise integrations, document your threat model and have a third-party security review.

UX & confirmation flows

Clear UX is essential to avoid user mistakes. Keep the on-client flow minimal: display the transaction amount, destination address, fees, and purpose. The device confirmation should act as the final and immutable consent. Avoid softening or abbreviating critical fields that appear on-device; users should be able to verify the full values before approving.

Consider these tips:

  • Show a readable summary on the app and require device confirmation for amounts and addresses longer than a threshold.
  • Allow users to flag transactions for review and to cancel pending broadcasts if needed.
  • Log confirmations and provide users with a transaction history that references device-approved signatures.

Testing and QA

Test on real hardware in addition to emulators. Edge cases such as interrupted transports, firmware updates, and malformed payloads appear most often on devices. Include regression tests for the signing flow and run integration tests that exercise invoice handling, multi-network support, and fee calculation.

Distribution & support

When releasing integrations, prepare a clear support article and step-by-step onboarding that helps users connect their Ledger device, manage app installations, and troubleshoot common connectivity issues. Provide links to Ledger Support and the Ledger Academy so users can access official troubleshooting and educational materials quickly.

Frequently Asked Questions (FAQ)

1. Do I need a Ledger hardware device to develop?
Yes — while some parts of development can be done with emulators, testing signing flows and confirmations should be performed on a real Ledger device to ensure accurate UX and transport behavior.
2. Can I store private keys on my server for faster UX?
No. Never store private keys or seed phrases on servers. Leverage the device for signing and use server-side state only to store unsigned transaction metadata and status.
3. Which transports are supported?
Common transports include WebUSB, HID, BLE for mobile, and USB for desktop. Choose the transport suitable for your target platform and always handle disconnects and retries.
4. Where can users get help if something goes wrong?
Point users to the official Ledger Support pages and your own support docs. Provide clear instructions for common connectivity issues and firmware steps.
5. Are there compliance or legal considerations?
Yes. Depending on your jurisdiction and whether you custody assets, you may need to follow financial regulations, KYC/AML rules, and consumer protection statutes. Consult legal counsel and document your compliance posture.
