Welcome. This deck introduces Ledger Live integration capabilities exposed by the Ledger Developer Portal. It covers APIs, SDKs, UX patterns, security best practices, developer onboarding, sample flows, and resources for shipping production-grade wallet integrations.
Integration with Ledger Live lets you provide users a secure, hardware-backed experience backed by Ledger’s firmware and key management—ideal for custodial-friendly flows or enhanced self-custody products.
Ledger exposes programmatic access to account discovery, transaction signing, and blockchain-specific operations via well-documented REST and WebSocket endpoints. Client SDKs for JavaScript and mobile simplify pairing with Ledger devices.
Choose a pattern based on control, compliance, and UX needs:
App talks to Ledger device or Ledger Live directly for account operations—low latency, full control.
Use Ledger-hosted pages for onboarding or signing to reduce integration overhead and improve trust signals for end users.
Provide clear steps: Connect device, open Ledger Live, approve pairing, verify account addresses on device, and complete test transaction. Keep prompts short and unambiguous.
Always mirror the device prompt in your UI and require address verification on the physical device for high-value operations.
Minimal privileges, explicit user consent, robust request signing, and replay protection. Use TLS everywhere and validate device attestation when available.
Rate-limit signing endpoints, maintain audit logs, and monitor abnormal signing activity to detect abuse quickly.
Handle device disconnects, user cancellations, and nonce or fee changes gracefully.
The Ledger Developer Portal provides SDKs, code samples, and interactive docs. Use the quickstart templates to reduce time to first-sign.
Open channels, forums, and clear issue trackers help accelerate troubleshooting and feedback loops.
Ledger’s plugin-style architecture allows adding chain-specific handlers for signing and transaction building without changing the core wallet.
Abstract blockchain differences behind clean interfaces to simplify product UX across assets.
Visit the Ledger Developer Portal for API references, SDK downloads, migration guides, and contact points for partnerships. Include integration tests early and plan for firmware/SDK updates.
Prototype a minimal flow, validate device prompts, then iterate on UX and monitoring.
Integrate with Ledger Live to deliver hardware-backed security, improve user trust, and support multi-chain flows. Follow the Developer Portal guides, adopt security best practices, and iterate with user testing.
Prototype, test on staging, and request early feedback from security and UX teams.
