Introduction
Welcome to the official Ledger® Live Wallet – Getting Started™ Developer Portal. This guide provides an end-to-end explanation for developers who want to integrate their applications with Ledger Live and the Ledger ecosystem. It covers installation, SDK usage, API connection, transaction flows, and essential testing steps for ensuring secure digital asset management.
Why Integrate with Ledger® Live?
Integrating with Ledger allows your app to tap into the industry’s most secure environment for cryptocurrency transactions. Developers gain access to a trusted hardware wallet ecosystem used by millions of users worldwide. Using the Ledger Live Wallet SDK, your dApp or service can request signatures, manage accounts, or show portfolio data within a secure interface.
For documentation and SDK examples, explore the Ledger Developer Documentation or the open-source LedgerJS library.
Installation and Setup
Start by installing Ledger Live on your desktop or mobile device from the official download page. Once installed, connect your Ledger device via USB or Bluetooth. Ensure you are running the latest firmware, and that the Ledger Live app recognizes your device.
Developers can also use LedgerHQ’s GitHub repositories for setup templates, testing utilities, and integration scripts.
Using the Ledger Live SDK
The Ledger Live SDK provides interfaces to connect external applications or dApps to the Ledger Live instance running on the user’s computer. It supports functions such as fetching accounts, constructing and signing transactions, and broadcasting them to supported networks.
Example SDK commands:
import TransportWebUSB from "@ledgerhq/hw-transport-webusb";
import AppEth from "@ledgerhq/hw-app-eth";
const transport = await TransportWebUSB.create();
const appEth = new AppEth(transport);
const address = await appEth.getAddress("44'/60'/0'/0/0");
console.log(address);
Security Considerations
Security is the core principle behind Ledger® Live. Your integration must never expose or request a user’s seed phrase or private keys. All signing must occur on the Ledger device, while your app coordinates with Ledger Live for data requests and broadcasting. Follow Ledger’s Security Guidelines to ensure compliance.
User Experience (UX) Best Practices
A great UX ensures user trust and adoption. Show clear on-screen prompts before asking for hardware confirmations, and guide users through steps like connecting their device, unlocking it, and approving transactions. Add contextual help via the Ledger Academy and offer direct links to Ledger Support.
Testing and Debugging
Before production deployment, test thoroughly using both emulators and physical devices. Validate that transaction data shown in-app matches what appears on the Ledger device screen. Use the WebUSB API for browser-based testing, or leverage test networks like Goerli or Polygon testnet for blockchain validation.
Deployment and Maintenance
Once your Ledger integration passes all quality assurance checks, document it thoroughly. Publish guides for users and provide a feedback channel for support issues. Keep your integration updated with the latest SDK versions and firmware compatibility as listed in the Ledger Developer Portal.
Follow the LedgerJS releases for updates and new API improvements.
Next Steps
