**Ledger Live Integrations**: Build the **Secure Blockchain Ecosystem**
The **Ledger Developer Portal** provides the official resources, **Hardware Wallet API**, and **App Development SDKs** required to integrate your applications directly into the Ledger Live environment, giving millions of users **Secure DApp Access**.
Connect your DeFi, NFT, and trading platforms to the world's most secure **Hardware Wallet** base.
const { LedgerWalletAPI } = require('@ledgerhq/hw-app-eth');
async function signTransaction(path, txData) {
// Establishing Secure Connectivity via Ledger Live
const transport = await LedgerLiveTransport.open();
const api = new LedgerWalletAPI(transport);
// Securely request signature on Hardware Wallet
const signature = await api.signTransaction(path, txData);
return signature;
}
// Key Component: The Ledger Live platform acts as the verified, secure bridge.
The **Hardware Wallet API**: Enabling Trustless **Secure Connectivity**
Our suite of tools ensures that **Secure Connectivity** is maintained between your application and the user's **Hardware Wallet**. The **Ledger Live SDK** is the core component that allows third-party services to access the device's signing capabilities *without* ever accessing the user's private keys. This is the foundation of **Digital Security** in the modern **Blockchain Ecosystem**.
**Ledger Live SDK**
The essential toolkit for embedding your **Secure DApp Access** directly into the Ledger Live application. This provides a seamless, verified user experience and handles all communication layers.
Transport Layer API
For deep, custom implementations, the **Hardware Wallet API** gives developers direct control over the communication protocol (BOLOS). Critical for advanced **App Development SDK** projects requiring bespoke interaction.
Account Descriptor Generator
Easily define and register new account types and derivation paths within Ledger Live, expanding support for unique wallets and complex **Digital Assets** structures within the **Blockchain Ecosystem**.
Pioneering **Secure DApp Access** Across the Ecosystem
The **Ledger Live Integrations** program supports a wide array of decentralized and centralized applications, ensuring that users can transact securely, whether swapping tokens, staking assets, or managing NFTs. Join the most trusted **Secure Blockchain Ecosystem**.
Integrate your decentralized exchanges, lending protocols, and yield farms. **Ledger Live SDK** ensures that complex transactions (approvals, swaps, liquidations) are signed securely on the **Hardware Wallet**. Trust is verified through **Secure Connectivity**.
Provide your users with a secure way to view and interact with their non-fungible **Digital Assets**. Our APIs support transparent message signing for NFT sales and minting, upholding the highest standards of **Digital Security**.
Build **App Development SDK** connectors that let users sign transactions initiated from external wallets (like MetaMask) using their Ledger device, further strengthening the **Secure Blockchain Ecosystem**.
Enable secure delegation and voting directly through the Ledger Live interface. The **Hardware Wallet API** handles the specific protocol requirements for PoS networks, streamlining **Secure Connectivity** for validator selection.
For enterprise partners, the **Ledger Developer Portal** offers dedicated support for building multi-signature schemes and customized custody solutions, all leveraging the unparalleled **Digital Security** of Ledger hardware.
Allow users to buy crypto directly into their **Hardware Wallet** accounts through verified partners. These **Ledger Live Integrations** ensure maximum fraud prevention and a seamless entry point into the **Blockchain Ecosystem**.
Your Journey on the **Ledger Developer Portal**
We provide extensive documentation and a dedicated support team to guide your **App Development SDK** project from concept to launch on the **Ledger Live Integrations** store. Security is built into every step of the process.

2. Build with the **Ledger Live SDK**
Develop your proof-of-concept using our open-source tools and mock environment for testing **Secure DApp Access**.
3. **Digital Security** Audit & Review
Submit your integration for a rigorous security audit by the Ledger team to ensure compliance and **Digital Security** standards.
4. Launch on **Ledger Live**
Go live! Millions of users gain immediate **Secure Connectivity** to your dApp, growing the **Blockchain Ecosystem**.
Example Code: Initializing the **Ledger Live SDK**
// Initialize the Ledger Live SDK to manage Secure DApp Access
const { createTransport, getDeviceInfo } = require('@ledgerhq/hw-transport-webhid');
async function connectLedger() {
try {
const transport = await createTransport();
const info = await getDeviceInfo(transport);
console.log(`Device connected: ${info.modelId}`);
// Proceed to use the Hardware Wallet API for signing logic...
return transport;
} catch (error) {
console.error("Ledger Connection Error:", error);
}
}
The simplicity of the **Ledger Live SDK** abstracts complex device communication, letting developers focus on the integration logic while guaranteeing **Secure Connectivity**.
