Ledger Live Integrations

Why integrate with Ledger Live?

Ledger Live is the primary companion app for Ledger hardware wallets, offering users a secure, unified interface for managing accounts, installing device apps, discovering decentralized applications, and using exchange/buy/sell services. Integrating with Ledger Live unlocks direct reach to millions of security-minded users while enabling tighter device interactions and better UX than a third-party integration alone. :contentReference[oaicite:0]{index=0}

Integration paths — at a glance

• Accounts / Blockchain: Add full node support, indexers, and account discovery so users can manage balances directly in Ledger Live. :contentReference[oaicite:1]{index=1}
• Live Apps (Discover): Integrate a dApp using the dApp browser or Ledger Services Kit to interact securely with a user’s device. :contentReference[oaicite:2]{index=2}
• Exchange & Payment providers: Implement provider endpoints so Ledger Live can surface buy, sell, or swap options from within the app. :contentReference[oaicite:3]{index=3}

Accounts & blockchain integration

If you maintain a blockchain or node infrastructure and want native support in Ledger Live, the accounts integration path is the place to start. This involves implementing account discovery, account balance APIs, and signing flows compatible with Ledger device apps. Ledger requests that teams coordinate via an intake form and legal agreement before development to ensure alignment with release policies and security requirements. :contentReference[oaicite:4]{index=4}

Developer tips

• Begin by documenting the RPC or indexer endpoints and the derivation schemes you support.
• Provide sandbox/testnet endpoints that Ledger can use for integration tests.
• Prepare clear upgrade and maintenance SLAs — Ledger may require continuous support for the network integration.

Live Apps: Discover & Ledger Services Kit

Live Apps (the Discover section inside Ledger Live) let web apps and dApps interact with user devices while preserving security guarantees. There are two main routes: using the dApp browser or integrating via the Ledger Services Kit (LSK) / Wallet API client. LSK provides React hooks and utilities to standardize device interactions, session management, and signing flows so your team can focus on UX rather than low-level plumbing. :contentReference[oaicite:5]{index=5}

// example (conceptual) Live App use
import { useLedger } from '@ledger/services-kit';
const { connect, sign } = useLedger();
// connect to device via Ledger Live, request signature...

Best practices for Live Apps

• Design concise, clear signing prompts — users must always understand what they're approving.
• Whitelist contract methods when possible (clear signing) so signature intent is explicit.
• Support both mobile and desktop flows: Ledger Live provides bridging for hardware devices across platforms.

Exchange / Buy / Sell integrations

Ledger Live surfaces third-party services for buying, selling, and swapping assets. Providers integrate by implementing specific endpoints and workflows so Ledger Live can orchestrate transactions, present quotes, and finalize settlements while keeping private keys on the user’s device. The integration architecture ensures a controlled flow of data between Ledger Live, Ledger backend services, and the provider. :contentReference[oaicite:6]{index=6}

Provider requirements

• Endpoint contracts for quotes, order creation, and webhooks.
• Robust reconciliation and dispute handling.
• Clear KYC/AML integration paths (if required by the service region).

Testing, submission & CI

Ledger provides CI workflows, testing checklists, and a submission process for apps and integrations. For Live Apps, run device interaction tests locally (using monorepo tooling and Wallet-API dev servers) and prepare detailed deliverables: docs, installation steps, test plans, and security notes. Automate your build/test pipeline to match Ledger’s expectations for review. :contentReference[oaicite:7]{index=7}

Checklist before submission

• Automated tests for signature flows and error handling.
• Security review: threat model, data minimization, and dependency audit.
• User-facing documentation: install instructions, account discoverability notes, and support contacts.

Security & UX — the Ledger way

Ledger’s integration model centers user keys on the hardware device while allowing partner services to provide data, execution, and settlement. This separation keeps private keys offline yet gives partners the ability to create rich experiences (e.g., swaps, staking, portfolio insights) that respect user consent and device-level approvals.

UX rules of thumb

• Minimize the number of signatures required — batch when safe.
• Surface human-readable transaction summaries before asking for a device approval.
• Fail gracefully: provide clear remediation steps when the device is disconnected or the ledger app version mismatches.

Getting started — a recommended roadmap

1. Read the docs: Start with the Ledger Developer Portal sections for Ledger Live, Live Apps, and the Services Kit.
2. Choose your path: Accounts support vs. Live App vs. Exchange integration.
3. Prototype locally: Use dev servers and the Wallet-API to test device interactions.
4. Coordinate with Ledger: Submit the intake form for blockchain integrations or the Live App submission for Discover placement.
5. Ship & iterate: Monitor integration health, gather user feedback, and maintain backward compatibility for device app versions.
