Ledger Live Integrations — Ledger Developer Portal
Official developer resources and guides for Ledger Live integrations, plugin development, SDKs and secure signing flows.
Build with security
Ledger Live Integrations — Build secure Ledger Live apps, plugins and deep integrations
The Ledger Live Integrations hub empowers developers to build fast, secure and user-friendly integrations with Ledger Live. Use Ledger Live APIs, SDKs and plugin architecture to enable device connection, transaction signing, account discovery, UX prompts, and enterprise-grade custody controls. Whether you are creating a Ledger Live plugin, integrating Ledger devices into your service, or building internal tooling, these integration guides prioritize secure signing flows, clear user consent, deterministic account derivation and robust error handling.
Device connection
Bridge and USB connection patterns, WebHID and WebUSB guidance, auto-detection, device permissions, and connection stability best practices for Ledger Live integrations.
Secure signing
Design flows that require explicit on-device confirmation for each signature. Use Ledger's signing APIs to keep private keys on-device and minimize attack surface for all Ledger Live integrations.
SDKs & samples
Official JavaScript, Rust, and mobile SDKs with sample apps, plugin scaffolding, and test harnesses for CI and automated device tests to validate Ledger Live integrations at scale.
Enterprise tools
Custody guidelines, device fleet management, audit logs, role-based access, and compliance-focused integration patterns for enterprises building with Ledger Live APIs.
Integration checklist — safe, smooth, Ledger Live ready
Follow device-first security: never export private keys; require on-device confirmations.
Use supported APIs: prefer official Ledger SDKs and documented RPC/JSON interfaces for account discovery and transaction building.
Implement explicit UX prompts: show clear transaction details in-app and require explicit on-device user consent.
Test with hardware: use real devices and emulators for integration tests and automated pipelines.
Support updates: monitor firmware and SDK changes and update integrations to remain compatible and secure.

Sample code snippet — build a signing request
This minimal example demonstrates a signing flow: build the transaction data, request the Ledger device to sign, and verify the returned signature. Use the official SDKs and follow wallet-specific serialization rules.
// PSEUDO sample (replace with official Ledger SDK calls)
const tx = buildTransaction({to: '0xabc...', value: '0.01'});
const transport = await TransportWebUSB.create();
const app = new LedgerApp(transport);
const signature = await app.signTransaction(accountIndex, tx);
verifySignature(signature, tx);
Best practices
Always show human-readable transaction details in your UI before requesting on-device signing.
Keep SDKs up-to-date and monitor deprecation notices.
Provide recovery guides and clear error messages when devices are disconnected or firmware mismatched.
FAQ
Can I build a Ledger Live plugin?
Yes — use the plugin scaffold, follow API guidelines and sign your plugin packages if required by the platform.
Do integrations require firmware changes?
Not usually. Design your integration to detect firmware versions and gracefully prompt users to update their device when necessary.
Is the SDK open-source?
Official SDKs and sample code are typically published under open-source licenses for review and community contributions. Check the repo for license details.
