Ledger Live Developer Portal

Introduction

Welcome to the Ledger Live Developer Portal — your secure, comprehensive hub for creating, integrating, and managing decentralized apps, hardware wallets, and blockchain assets with the robust support of Ledger’s infrastructure. As the crypto world rapidly expands, the importance of user security, seamless integration, and transparency becomes more critical than ever.

Ledger Live is more than just a wallet — it’s a powerful interface for digital asset management, hardware wallet integration, and a full suite of APIs designed for developers building the future of blockchain apps. Whether you’re building decentralized finance (DeFi) solutions, crypto analytics dashboards, or secure key management systems, Ledger Live provides the secure foundation to build on.

Through this portal, we empower developers to access Ledger Live SDKs, APIs, documentation, tutorials, and tools — all crafted to simplify development, maximize security, and scale crypto apps to the masses.

Key Features

Ledger Live Developer Portal offers a wide range of features designed for modern crypto development. Here are just a few highlights:

• Secure SDK Integration: Easily connect apps with Ledger hardware devices using our open-source SDKs (JavaScript, TypeScript, Rust).
• Ledger Connect: Enable seamless browser-based interaction with Ledger hardware wallets.
• Real-time Crypto Tracking: Fetch live market data, portfolio values, and transaction history through our APIs.
• Multi-chain Support: Build for Ethereum, Bitcoin, Solana, and 25+ blockchains with the same integration layer.
• Custom App Development: Extend Ledger’s functionality by building apps that run directly on Ledger hardware.

APIs and SDKs

Ledger Live provides a variety of tools to empower developers to interact with the Ledger ecosystem:

Ledger Live SDK

A powerful JavaScript SDK that allows interaction with Ledger hardware wallets via USB, Bluetooth, or Ledger Connect. Use it to sign transactions, fetch account data, or manage crypto assets directly from your app.

Ledger Market API

Integrate real-time market data for hundreds of coins and tokens. Ideal for building wallets, trading dashboards, and portfolio trackers.

App API

Access APIs to build native apps for Ledger devices using BOLOS (Blockchain Open Ledger Operating System). Build, test, and deploy your own Ledger Nano applications.

Security by Design

Security is the cornerstone of everything we build at Ledger. Our solutions are engineered with industry-leading secure elements, proprietary operating systems, and open-source transparency. Developers building with Ledger Live get the benefit of this robust security model.

Every API call and integration point is carefully audited, and our SDKs are designed to prevent unauthorized access or leaking of private keys. Using Ledger Live SDK ensures your app never handles the keys directly — minimizing the attack surface.

Security reviews, community-driven code audits, and Ledger’s bug bounty programs reinforce our commitment to secure development.
