Overview — Ledger Live Integrations on the Ledger Developer Portal
Ledger Live integrations are the official method for connecting applications, services, and custom tooling to Ledger hardware wallets. The Ledger Developer Portal documents best practices, APIs, SDKs, and design patterns for Ledger Live integrations so developers can securely integrate with Ledger Live and deliver seamless experiences. Whether you are building a DeFi integration, an exchange plugin, or a wallet connector, Ledger Live integrations provide a secure, consistent bridge to Ledger devices.
Key capabilities of Ledger Live Integrations
- Secure device pairing — Ledger Live integrations use the Ledger device for confirmed signing and secure approval.
- Cross-platform SDKs — Official SDKs and libraries for building Ledger Live integrations on web and desktop.
- Transaction flows — Standardized signing flows to support tokens, smart contracts and multi-account setups.
- Developer tooling — Emulators, test networks, and documentation in the Ledger Developer Portal.
- Compliance & verification — Guidelines to keep your Ledger Live integrations verified and user-trustworthy.
- UX patterns — Recommended UX for prompts, device confirmation, and failure handling.
Building Ledger Live Integrations — essentials from the Ledger Developer Portal
Building Ledger Live integrations means designing for security-first interactions. Start by reading the Ledger Developer Portal: follow the integration checklist, use the official Ledger SDKs, sign communication with recommended cryptographic practices, and verify messages on-device. Ledger Live integrations must never require sharing private keys or recovery phrases; all signing happens on the Ledger hardware and the Ledger device displays human-readable prompts for the user to confirm. The Ledger Developer Portal contains sample code, API references, and integration tests to accelerate development of Ledger Live integrations.
Testing and verification
Proper testing is vital. The Ledger Developer Portal provides emulators and recommended testnets for safe integration tests. Simulate user flows, test error handling, and validate corner-cases such as interrupted USB sessions or denied device confirmations. After testing, follow the Portal’s guidance to submit your Ledger Live integration for verification and review — verified Ledger Live integrations increase user trust and visibility.
UX and security patterns
UX matters: Ledger Live integrations should clearly instruct users when to connect devices, what to expect on-screen, and how to review transactions on their Ledger device. Use consistent labeling, avoid ambiguous prompts, and provide recovery instructions in-line. From a security perspective, always validate firmware versions, display short human-readable messages for transaction recipients, and keep network traffic encrypted. The Ledger Developer Portal contains curated UX patterns specifically tailored for Ledger Live integrations to maximize clarity and safety.
Deploying and maintaining integrations
Once your Ledger Live integration is verified, maintain it actively: monitor for firmware or protocol updates, keep SDKs current, and respond to user reports quickly. The Ledger Developer Portal recommends a lifecycle approach for Ledger Live integrations — plan for versioning, deprecation notices, and secure update mechanisms. High-quality Ledger Live integrations never compromise user security for convenience.
Examples & use-cases for Ledger Live Integrations
Common Ledger Live integrations include exchange withdrawal tools that allow users to sign withdrawals via Ledger Live integrations, DeFi dashboard connectors that display on-chain positions while using Ledger for signing, and custodial-onboarding flows where Ledger Live integrations ensure each transaction is verified on-device. The Ledger Developer Portal includes reference implementations for many of these use-cases to shorten your development time.
Final notes from the Ledger Developer Portal
Ledger Live integrations are a powerful way to extend the Ledger ecosystem while preserving the security guarantees users expect. Follow the Ledger Developer Portal’s guidance, prioritize device-based confirmation, and integrate thoughtfully. Good Ledger Live integrations are secure, performant, and respectful of user privacy — build them accordingly.
