Integration Methods

API-Based Integration

Ledger Live exposes APIs that allow your application to interact with supported cryptocurrencies securely. Examples include reading account balances and submitting signed transactions.

fetch('https://api.ledger.com/v1/accounts')
  .then(response => response.json())
  .then(data => console.log(data));

SDK-Based Integration

The Ledger SDK allows developers to directly communicate with Ledger devices. SDKs are available in multiple languages, including JavaScript, Python, and Go.

const TransportNodeHid = require('@ledgerhq/hw-transport-node-hid').default;
const AppBtc = require('@ledgerhq/hw-app-btc').default;

const transport = await TransportNodeHid.create();
const btc = new AppBtc(transport);
const result = await btc.getWalletPublicKey("44'/0'/0'/0/0");
console.log(result);
