What are Ledger Live integrations?
Short definition
Ledger Live integrations allow third-party applications and services to interact securely with Ledger hardware wallets and the Ledger Live desktop/mobile experience. Integrations can enable onboarding, transaction signing, portfolio display, and advanced features like staking or app management from an external UI while preserving key security properties of the hardware wallet.
Why this matters
By integrating with Ledger Live, partners deliver a trusted hardware-backed flow to their users — improving retention, increasing transactions, and reducing custody risk. This document focuses on architecture, security considerations, SDKs, and recommended UX patterns for successful integrations.
2 — Why integrate with Ledger Live?

Benefits for partners
Security-first experience: Use the hardware wallet for private key operations.
Brand trust: Leveraging Ledger’s reputation reduces friction when users deposit or trade assets.
Feature parity: Access to multi-chain support and Ledger Live’s ongoing updates.
Business outcomes
Integrations can translate into higher conversion for onboarding flows, lower customer support for custody-related issues, and more predictable compliance posture because private keys never leave the device. For product teams, think of integrations as a way to blend your UX with Ledger’s security guarantees.
3 — Architecture & Data Flow

Slide 3 / 10
Typical integration components
At a glance, a Ledger Live integration usually involves these components:
Third-party frontend: Your website or app that starts onboarding or transaction flows.
Ledger Live bridge/gateway: A connector that mediates secure requests to the hardware wallet (often via Ledger Live APIs or SDKs).
Hardware device: The Ledger device that performs private key operations.
Never send private keys to the cloud. The third-party app should prepare unsigned payloads and prompt the device via the user’s Ledger Live application to sign them locally. Signed payloads can then be broadcast via backend nodes or third-party relayers.
4 — Security considerations
Suggested time: 2 min
Slide 4 / 10
Threat model
Assume the user’s host environment may be compromised. Design flows so that critical secrets (private keys, recovery phrases) remain isolated in the hardware. Use attestation and transaction preview verification on-device.
Best practices
Use well-audited SDKs and follow official Ledger Developer Portal guidelines.
Present clear transaction metadata to users on the device display.
Log minimal telemetry and ensure no sensitive fields are stored.
5 — SDKs, APIs, and tools
Suggested time: 1.5 min
Slide 5 / 10
What to use
Ledger provides platform SDKs for interacting with Ledger devices and Ledger Live connection points (for example, bridge libraries, Bluetooth integrations, and platform-specific helpers). Use the official SDKs to ensure compatibility across firmware versions and devices.
Developer workflow
Read documentation and integration guides on the Ledger Developer Portal.
Install and prototype with sandboxed SDK examples (local testnets).
Implement CI tests that mock signing flows and validate UX edge cases.
6 — UX patterns and recommended flows
Suggested time: 2 min
Slide 6 / 10
Onboarding
When using Ledger integration for onboarding, streamline the flow: explain hardware steps, detect Ledger Live presence, prompt the user to connect, and provide clear fallback instructions if Ledger Live is absent.
Transaction signing
Show a clear summary before requesting a signature. Use concise language and include amounts, recipient addresses, and fees. Let users cancel at any time and surface on-device confirmation as the single source of truth.
7 — Testing & QA
Suggested time: 1.5 min
Slide 7 / 10
Automated tests
Mock signing flows in unit tests. Use emulators or dedicated test devices where possible. Validate negative scenarios like rejected signatures, device disconnects, and malformed payloads.
Manual checks
Conduct manual end-to-end tests on each major platform (Windows, macOS, iOS, Android) and every Ledger device model you intend to support.
8 — Go-to-market & compliance
Suggested time: 1 min
Slide 8 / 10
Partner alignment
Coordinate messaging to highlight security and user control. Include brand co-marketing where appropriate and ensure legal/compliance teams review custody representations.
Documentation & support
Publish integration FAQs, troubleshooting guides, and a dedicated support path for Ledger-related issues. Clear developer docs reduce time-to-integration and support load.
9 — Example case study (hypothetical)

Fintech app integrates Ledger Live
A mid-size fintech integrated Ledger Live to offer hardware-backed custody for high-value transactions. Results within three months: a 28% increase in completed high-value transfers, 18% lower support tickets related to account compromise, and improved user NPS for crypto power-users.
Key takeaways
Clear onboarding and in-app education are essential.
Testing across devices prevented regressions during a firmware update.
Joint marketing amplified adoption among the target audience.
