Detailed Plan

Using data from cardanoscan.io and using the Ethereum account code in Ledger Live as a reference should allow for Cardano to have full account support in Ledger Live for both ADA and tokens. This proposal includes support for Cardano in both the desktop and mobile versions of Ledger Live. This integration will not enable the purchase of ADA in the Ledger Live app.

I estimate that the completing the code would take approximately 2 months for both desktop and mobile, for 4 months total development time. The goal of this proposal is to have Cardano account support merged into Ledger Live within 6 months after being funded. The development will be done using public forks of the Ledger Live apps on my GitHub account (https://github.com/KazW) so that progress can be monitored by the community.

This will be built during my weekends, I’m willing to dedicate 16 hours per weekend to meet the goal of completing the integration within 4 months. This means I would spend a total of 256 hours of development time over those 4 months. At a cost of $50/hour this comes to $12,800, I have added a ~20% margin to this in order to address any potential changes that may be required to make the code acceptable to the Ledger Live team.

The primary risk with this proposal is that 2 pull requests would need to be accepted by the Ledger Live team, one for desktop support, and another for mobile. This is a risk since ultimately, the decision to accept the code into Ledger Live is left to a 3rd party and not one of the authors of this proposal. To mitigate this risk, I have added a margin to the budget to allow for the Ledger Live team to request code changes during the review process.
