GLedger Live Integrations – Ledger Developer Portal
A concise, developer-focused presentation that explains integration paths to bring services, wallets and Live Apps into Ledger Live. This document combines practical guidance, best practices, and direct links to official resources for engineers and product owners.
Overview
Ledger Live is the gateway between Ledger hardware and the broader crypto ecosystem. Integrations fall into three primary categories: Accounts (blockchain support), Live Apps (dApps inside Ledger Live) and Companion Services (custodial & non-custodial services accessible from within the app). Successful integrations prioritize security, UX parity with Ledger standards and compliance with Ledger’s submission process.
Why integrate with Ledger Live?
Integrating with Ledger Live increases your product's reach to millions of security-conscious users, provides a hardened path to custody and signing operations using Ledger devices, and leverages Ledger’s secure communication primitives (the Ledger Services Kit). From a product perspective, integrations improve user trust and reduce onboarding friction.
Primary integration patterns
1. Accounts / Blockchain integration: Add native blockchain support so users can manage accounts directly in Ledger Live.
2. Live Apps (Web / dApp inside Ledger Live): Embed web-based dApps that can request signatures and securely interact with the ledger device via the Services Kit.
3. Wallet & Service integrations: Connect external wallets, exchanges, or custodial platforms through official channels to offer additional services (swaps, staking, bridge flows) inside Ledger Live.
Security & submission requirements
Ledger enforces a rigorous app submission and review process. Third-party teams must provide complete documentation, testing artifacts and user support instructions. Applications that interact with device-level features must comply with Ledger’s SDK and BOLOS constraints. Always consult the submission guidelines early — many integration delays come from incomplete deliverables.
Developer workflow
- Read the Ledger Developer Portal docs and choose the correct integration path (Accounts, Live App, or Partner Service).
- Prototype locally using the Ledger Live monorepo and SDK emulators (Speculos for device emulation).
- Run end-to-end tests with hardware devices and gather required documentation.
- Submit the app or integration plan to Ledger and follow the deliverables checklist.
Practical tips (UX & testing)
- Provide clear in-app instructions: users must know when an operation requires their device.
- Fail gracefully: if a device is not connected, surface clear remediation steps instead of cryptic errors.
- Local testing: emulate the device when iterating rapidly, but always validate on real hardware before submission.
- Security reviews: schedule time for code audits and address potential blind-signing vectors.
Official resources (10 colorful official links)
Below are the most relevant official resources to get started — each link is styled for quick visual scanning during a presentation.
Example integration checklist (copyable)
<!-- checklist snippet -->
1) Confirm integration path (Account / Live App / Partner)
2) Fork ledger-live (if modifying UI flows) and boot local build
3) Implement Services Kit calls (Live App) or account sync (Accounts)
4) Write step-by-step user guide and publish demo/tutorial
5) Run device tests (Speculos + real hardware)
6) Submit deliverables & support plan to Ledger
Presentation-ready talking points (for stakeholders)
- Market reach: access Ledger’s user base and increase trust.
- Security-by-design: transactions are signed on-device; no private keys leave the device.
- Operational control: Ledger’s review process helps maintain UX and security standards.
- Time to market: plan for review cycles and documentation — factor these into launch timelines.
Closing & next steps
Start by choosing the right integration path and bookmarking the official resources above. Early outreach to Ledger (via the Developer Portal forms) helps align expectations and reduces review friction.
