Ledger Live is the official desktop and mobile application from Ledger that allows users to securely manage cryptocurrencies. Integrating Ledger Live into your applications can provide users with seamless, secure access to their crypto assets, while leveraging the safety of Ledger hardware wallets.
Ledger Live is designed to interact with Ledger hardware wallets to perform tasks such as sending, receiving, and managing cryptocurrencies. It supports multiple blockchain networks and provides a user-friendly interface that prioritizes security.
The Ledger Developer Portal offers a complete set of tools, SDKs, and documentation for developers interested in integrating with Ledger Live.
Ledger provides several SDKs to streamline integration:
The Ledger Live API allows developers to fetch real-time portfolio data, initiate transactions, and perform device management operations securely. You can find API documentation here.
When integrating Ledger Live:
Use the Ledger Live SDK to connect your app to the Ledger device. Example code snippet:
const LedgerApp = require('@ledgerhq/hw-app-eth');
const TransportNodeHid = require('@ledgerhq/hw-transport-node-hid');
async function connectLedger() {
const transport = await TransportNodeHid.create();
const ledger = new LedgerApp(transport);
console.log(await ledger.getAddress("44'/60'/0'/0/0"));
}
connectLedger();
Retrieve account balances and transaction history directly from Ledger Live:
const accounts = await ledger.getAccounts();
console.log(accounts);
Transactions must be signed on the Ledger hardware device for maximum security. Never sign transactions in an unsafe environment.
Ledger emphasizes security at every layer. Some key considerations:
Developers can create custom apps using the Nano App SDK. This allows for specialized blockchain functionality and deeper integrations.
Ledger Live supports third-party integrations for:
Integrating Ledger Live into your applications provides users with a secure, convenient, and trusted way to manage cryptocurrencies. By following the official SDKs, APIs, and best practices, developers can create powerful applications that leverage the safety of Ledger hardware wallets.
