Ledger Live Integration

Cardano Integration - Ledger Live

OVERVIEW

Our mission at Ledger is to be the secure gateway to all Digital Assets.

To achieve this objective, we provide a unique combination of Secure Hardware (Ledger Nano S and X) and easy-to-use Multi-Chain Software: Ledger Live. We are the only platform able to support new chains, coins, and apps as they come.

Currently, more than 4 million Ledger Hardware wallets have been sold in over 165 countries.

As Cardano is the 3rd biggest cryptocurrency, its integration in Ledger Live is strongly requested by our users.

By implementing Cardano in Ledger Live, users can directly store, send, receive and stake their ADA with our convenient desktop and mobile applications.

Furthermore, this integration would pave the way to supporting Cardano DApps in the Ledger Live Discover section, thus continuing to promote security and ease of use for every Ledger user.

This Proposal is our very first step with Project Catalyst and the Catalyst Community. We are glad to become a part of the Cardano community and looking forward to building with you on Cardano. Our Collaboration with the Ambassadors Guild helps us to act respectfully in regard to the Cardano and CAtalyst Ecosystem and Community.

The Ledger Live Desktop and Mobile app is open source, this integration and development will be open source and made available on Ledger's GitHub.

We would like to propose using Cardanoscan/Typhonwallet's proprietary backend as the indexer (backend) service. We have proved to be stable, correct, and fast service in the Cardano ecosystem. Our indexer backend system is developed from the ground up following the original Cardano ledger specs. This gives us full control of how we develop, maintain, and evolve the platform.

Please note the costs above mentioned are for Phase 1 only.

Future Development

Once the phase 1 is complete, other proposals will be submitted to Catalyst to discuss Phase 2 and 3

Phase 2 Scope: Staking of ADA, Catalyst Voting Support on Ledger Live Desktop and Ledger Live Mobile

Phase 3 Scope: DApp support on Ledger Live Discover? Staking Center Enhancements? NFT Enhancements?

OUR COMMITMENT AT LEDGER

We commit to supporting this initiative end-to-end by providing skilled internal resources for successful integration, as well as financial support to the Strica team in order for them to operate and maintain their back-end service for Ledger users.

Should it become required, Ledger also commits to providing internal resources to help modify the existing Cardano Nano application (currently developed and maintained by VacuumLabs), as well as expedite subsequent security audits.

FINANCE

Impact

This Proposal is based on an open-source integration of Ledger and therefore correctly based in the Challenge. We were not sure if the dApps & Integrations Challenge would not fit better to this proposal but we think that the open-source aspect of the proposal has more weight than its integrational part.

Feasibility

The Team is built by community members which have proven in the past that they have a profound knowledge of required skill sets and expertise to successfully execute this Proposal

Auditability

As the process and progress of the Proposals execution will be publicly available on GitHub the auditing process can be done effectively and transparent
