Ledger Live Integrations in the Ledger Developer Portal provides everything teams need to integrate Ledger hardware and Ledger Live into wallets, exchanges, DeFi apps and enterprise platforms. Explore SDKs, API references, test flows, and security guidance to bring hardware-backed keys to your application.

What is Ledger Live Integration?

Ledger Live integration refers to the set of APIs, SDKs, libraries and recommended workflows published in the Ledger Developer Portal that let developers communicate with Ledger devices and Ledger Live. Whether you are adding hardware-wallet support to a web wallet, connecting a custodial platform, or building a native desktop integration, Ledger Live integrations deliver hardware security, transaction signing, and user-friendly confirmation UX.

Why integrate with Ledger Live?

Security matters — Ledger Live Integrations allow applications to pair with a Ledger hardware device, orchestrate secure transaction signing, verify address derivation using BIP standards, and manage multi-chain flows. Integrating with Ledger Live accelerates user trust, reduces key-management liability, and unlocks Ledger’s strong device-based approval UX. The Ledger Developer Portal centralizes integration patterns, sample code, and official SDK downloads so teams ship quickly while staying secure.

Core components

Ledger SDKs

Multi-language SDKs (JavaScript, TypeScript, Kotlin, Swift) that interface with Ledger devices and Ledger Live for transport, signing, and app management.

Ledger API & Protocols

Transport and protocol layers for secure messaging (APDU) with deterministic derivation paths and secure attestation checks.

Reference Apps

Sample integrations, example UIs and production-ready reference designs that demonstrate Ledger Live flows and user consent experiences.

How it works (high level)

Integrations typically use a three-step pattern: (1) discovery and pairing with the Ledger device, (2) preparation of transaction payloads and metadata, and (3) invoking Ledger Live or the device to present a confirmation for signing. The Ledger Developer Portal provides a complete testnet sandbox, recommended derivation schemes, and transaction examples so developers can validate flows before going live.

Best practices

Follow the official SDKs and keep your dependencies updated.
Use deterministic derivation and clear path descriptions for reproducible addresses.
Implement attestation and firmware checks to ensure authenticity of the connected device.
Design clear, secure confirmation UX — never automate approval flows.

Supported use cases

Ledger Live Integrations support a wide range of use cases: consumer wallets, custodial platforms, exchanges, NFT marketplaces, and DeFi interfaces. Each use case benefits from hardware-backed signing and Ledger’s trusted UX for final approval. The Developer Portal includes specific patterns for each scenario, plus auditing checklists for compliance and risk management teams.

Getting started

Start with the quickstart on the Ledger Developer Portal: install the official SDK, run the sample app, connect a Ledger device, and try a test transaction on testnet. The portal contains migration guides and common troubleshooting steps so teams can integrate Ledger Live reliably and securely.

Support & community

Official support channels, community forums, and developer chats accelerate problem solving. The Ledger Developer Portal links to GitHub repos, SDK documentation, and changelogs to help teams stay in sync with the latest Ledger Live Integrations updates.
