Ledger Live Integrations - Ledger Developer Portal

Introduction

Ledger Live is the flagship companion app enabling users to securely manage cryptocurrencies and digital assets with Ledger hardware wallets. Integration of blockchains, dApps, and services into Ledger Live is achieved via the Developer Portal, a dedicated platform for engineers and product owners to leverage official tools, APIs, and documentation[web:1][web:4][web:5].

Overview of Ledger Developer Portal

The Ledger Developer Portal acts as a centralized hub for blockchain developers, offering structured documentation, SDKs, example code, and community support. As the only official access point, it assures security and streamlines the process of bringing your blockchain, dApp, or service to Ledger’s trusted environment[web:3][web:4][web:7].

Why Integrate?

• Reach millions of Ledger Live users with your blockchain or dApp[web:4][web:5].
• Benefit from Ledger’s battle-tested security infrastructure and best practices[web:7][web:8].
• Participate in global developer community forums and get expert feedback[web:4][web:6].
• Access all resources for integration, testing, and deployment from one platform[web:3][web:9].

Integration Paths

Ledger Live supports multiple integration tracks:

• Native Blockchain Integration: Add direct account support for new tokens or protocols.
• Live Apps (dApps): Embed web3 apps directly into the Discover section.
• Device Apps: Submit custom apps or plugins running on Ledger hardware for protocol-level signing.
• Exchange Providers: Integrate swap, sell, buy, or card services[web:1][web:5].

Quick Decision Guide

Choose the integration path based on your project needs:

• For on-device logic: select the Device App track.
• For in-app UX: choose the Live App path using Ledger Services Kit or Wallet API.
• For both: combine application types, following official documentation templates[web:2][web:5].

Accounts & Blockchain Integration

Native blockchain integrations allow users to view balances, create accounts, and sign transactions directly in Ledger Live. This requires alignment with Ledger’s development processes and security requirements. Interested projects must coordinate with Ledger teams, review agreements, and follow documentation before beginning development[web:1][web:2][web:5].

Process Steps

1. Sign the required integration agreements.
2. Develop your blockchain app for Ledger hardware, following official guidelines.
3. Document clear install instructions, test accounts, and security features for review.
4. Submit via the Ledger Developer Portal’s integration form[web:1][web:2][web:9].

Key Documentation

Refer to the official introduction and blockchain support sections for full requirements, checklists, and current supported currencies[web:2][web:9].

Live App & dApp Integration

Live Apps are web3 or browser-based applications that are embedded directly inside Ledger Live through Discover. These integrations use the Ledger Services Kit or Wallet API to enable secure transaction signing and seamless user experiences inside the app’s own environment[web:4][web:5][web:6].

Integration Workflow

1. Develop your dApp using Ledger’s Services Kit for secure interactions[web:5][web:6].
2. Enable developer mode in Ledger Live to test and preview your app in the Discover environment.
3. Prepare clear documentation and submit according to the Live App Submission Guide[web:6][web:8].

Best Practices

• Implement clear signing for every transaction—especially for EVM chains—so users see exactly what they’ll approve[web:5][web:8].
• Follow UX guidelines and test regularly using the developer mode toggle.
• Reference SDK documentation for full API contracts and security models[web:5][web:6].

Device App Integration

Device apps are written in C or Rust, run on the Ledger hardware itself, and handle low-level protocol signing or cryptography. Integration of device apps requires close adherence to security guidelines and review—submission should include installable binaries and comprehensive usage documentation[web:5][web:9].

Submission Steps

1. Develop your device app using Ledger’s official development toolchain.
2. Submit binaries, install guides, and documentation through the dedicated Device App portal section.
3. Work with Ledger review teams to assure compliance and optimize security[web:2][web:5].

Developer Tools and Resources

• Full documentation for APIs, signing flows, and release processes at developers.ledger.com/docs[web:1][web:3].
• Official SDK kits and templates for wallet connections and dApp discovery[web:5][web:6][web:8].
• Example code, community best practices, and forums for troubleshooting and improvement[web:3][web:4][web:7].

Testing Environment

Use developer toggles in Ledger Live to access sandbox modes for rigorous integration testing before submitting your application[web:5][web:6].

Security Practices

Security is paramount in all Ledger integrations. Device-side code must remain minimal, and sensitive cryptography should be performed on-device. Never expose private keys, seeds, or credentials to remote services. Follow the strict security guidelines to ensure both user trust and compliance[web:2][web:5][web:7].

Key Concepts

• Explicit signing and transaction review to reduce ‘blind signing’ risks[web:9][web:5].
• Regularly update your Ledger device and review API key usage.
• Participate in security audits and adhere to submission checklists.

Submission Process and Best Practices

1. Prepare all documentation: install guides, usage instructions, test accounts, security notes.
2. For device apps, provide installable binaries and verification materials.
3. Follow the official submission checklist and guidance for each integration path[web:1][web:2][web:5].
4. Iterate using community feedback before public release.

Common Pitfalls

• Skipping Ledger’s integration agreements and security review.
• Sending sensitive data off-device (never permitted).
• Unclear transaction signing flows can risk user safety.
• Poor documentation delays approval cycles[web:2][web:5][web:9].

Community and Support

Join Ledger’s open developer community forums for troubleshooting, best practice sharing, and collaboration. Expert support from Ledger engineers is available for all integration tracks. Stay updated with new features, announcements, and ecosystem milestones via the official Ledger Blog[web:4][web:6][web:8].
