Developer & API Integration

Use Ledger’s modular Wallet API to build your own integrations, Live Apps, and custom tools.

Wallet API (TypeScript): Manage accounts, sign messages, swap assets, and more
Live Apps: Plug external apps into Ledger Live for direct user access via the hardware wallet
Security Guarantee: No external app ever sees private keys; all sensitive operations handled in hardware
Open Source SDK & Docs: Full modular documentation and public repositories for devs!

Sample API Call:

import { WalletAPIClient } from "@ledgerhq/wallet-api-client";
const client = new WalletAPIClient({ 
  url: "http://localhost:1234",
  appName: "My Custom App"
});
const accounts = await client.listAccounts();

Operational Best Practices

Always visually verify destination addresses and transaction details on your Ledger device
Update Ledger Live and device firmware regularly
Use strong passwords and device auto-lock
Review connected apps and dApps periodically

Pro Tip: Never trust address details shown solely on your computer—your Ledger screen is always the authority!
