Ledger Live Integration #2

[IMPACT] 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)

[IMPACT] 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

[IMPACT] 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 

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

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.
