Ledger Live is the official application to manage Ledger hardware wallets. Developers can integrate Ledger Live into their applications using the Ledger Developer Portal. These integrations allow secure transaction signing, balance tracking, and account management directly from third-party apps.
Integrating Ledger Live ensures that your application benefits from Ledger's robust security model, seamless user experience, and official support channels. It reduces the risk of security vulnerabilities and enhances user trust.

The Ledger Live API provides endpoints to interact with accounts, transactions, and device features. Developers can use REST or WebSocket interfaces for real-time data.

Ledger offers SDKs for multiple programming languages to simplify integration. The SDKs provide pre-built functions to handle transaction signing, device communication, and account management.
For Node.js, use:
npm install @ledgerhq/hw-app-eth
npm install @ledgerhq/hw-transport-node-hid
Example to get Ethereum account balance:
const TransportNodeHid = require("@ledgerhq/hw-transport-node-hid").default;
const AppEth = require("@ledgerhq/hw-app-eth").default;
async function getBalance() {
const transport = await TransportNodeHid.create();
const eth = new AppEth(transport);
const result = await eth.getAddress("44'/60'/0'/0/0");
console.log(result);
}
getBalance();
