Please describe your proposed solution.

As mentioned above, this proposal aims to unlock phase #2 of the Ledger Live integration and to provide easy access to ADA staking within Ledger Live application.

Ledger, Strica, Vacuum Labs and Cardano ambassadors will also conduct a join study on how to potentially implement:

• Full Cardano Native token support on Ledger Live (not limited to a shortlist)
• Cardano Dapp browser on Ledger Live (to allow Dapps to be accessible through Ledger Live Discover section)

Please describe how your proposed solution will address the Challenge that you have submitted it in.

As this proposal is all about the integrations of products, the presented proposals here fits greatly into the dApps, products and Integrations Challenge.

Ledger Live is a well-known global product for blockchain communities and ecosystems, a further integration to the Cardano Blockchain opens new entry doors for us as Cardano Ecosystem, and Ledger users benefit greatly from improved and implemented services & functionalities

This proposal drives as well to a collaborative continuation between Ledger & the Cardano Community via participating in project Catalyst. Our goal is to explore & establish long term relations between the Cardano ecosystem and blockchain enterprises like Ledger. A sustainable and healthy relationship is highly beneficial for both Ledger and Cardano. It also greatly facilitates the Cardano Blockchain user adoption.

This Proposal will unlock additional features for Ada holders using the Ledger device and improve and increase greatly the interaction of Ada holders with the Cardano Ecosystem.

This proposal also unlocks new ways for Cardano Developers to engage in building new applications & platforms on the Ledger device

What are the main risks that could prevent you from delivering the project successfully and please explain how you will mitigate each risk?

The main risk we have to face has been discovered in the implementation of the Ledger Live integration #1. The development had to face technical challenges and risks, and we had several times the risks to not deliver in the proposed timeline as the roll-out became far more complex than initially expected.

To mitigate this risk, and to learn from our mistakes, we extend the milestones and the roadmap of this proposal over a longer time frame.

We also want to take a safe approach by conducting a feasibility study before kickstarting any development related to both:

• Full Cardano Native Assets support
• Cardano Dapp browser

Please provide a detailed plan, including timeline and key milestones for delivering your proposal.

Q3 2022

Continuing further improvements of the Ledger Live integration in collaboration with ledger, Strica & the Cardano Ambassadors Guild. Kickstart the technical and product specification phase regarding staking in Ledger Live.

Q4 2022

-Implementing Staking functionality to Ledger Live applications

-Conducting a research and development work in order to identify solutions to be able to list Cardano Native Assets

If you are funded, will you return to Catalyst in a later round for further funding? Please explain why / why not.

As we envision further development for the Ledger Live integrations such as NFT enhancements & voting, this proposal may most likely return in a future funding round to Project Catalyst and to prove the potential & possibilities of strong collaborations

Please describe what you will measure to track your project's progress, and how will you measure these?

Successful implementations are tracked on github

What does success for this project look like?

Success of this proposal would be a successfully implemented staking functionality to Ledger Live and a healthy & growing collaboration between Ledger & the Cardano Community and Project Catalyst.

Success will also be determined by the ability to assess the feasibility of both full token support and Cardano Dapp browser in Ledger Live.

Ledger users will greatly benefit from improved integrations, and Cardano can count on strong support & relationship to the Ledger Team.

Please provide information on whether this proposal is a continuation of a previously funded project in Catalyst or an entirely new one.

This Proposal is a direct continuation of the Ledger - Live Integration Proposal from Project Catalyst Fund 7. This proposal has been successfully implemented, as millions of users can prove. However, next steps are required to drive this collaboration & development forward

In June 2022, Cardano was the third most installed application on Ledger Hardware wallet (right after Bitcoin and Ethereum). It also showed the strongest growth in terms of number of accounts synchronised on Ledger Live.

This demonstrates the impact of the first phase of the integration on the Ledger and Cardano user bases.
