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**.
