Ledger App Rewrite
michal_petro
Descrição
Work with Ledger team to design new UI according to the expectations. Implement new UI into the Cardano Ledger App. Pass the external audit process (costs for this shall be included in proposal). Support the Ledger team by the release process.
Declaração do Problema
In 2018 when Ledger Cardano App was developed, there was no standard for embedded app UI. Over the years this changed and now Cardano is the only Ledger application with non-standard UI such as requiring double-click several times during the confirmation process. This is causing confusion among users and problems with testing because the design is not compatible with the testing suite.
Benefício da Proposta
Ledger wallet users will have better Cardano experience. Further app updates and releases will be faster and cheaper due to Ledger testing suite compatibility.

I wonder if we don't do that, would Ledger eventually integrate with us, because if they don't, they risk losing users who move to other devices? We have previously also funded near millions to integrate with Ledger updates through Catalyst.
From a workshop, the North American Community Hub summarized feedback noting the Ledger App Rewrite’s usability goals but highlighting unclear metrics and Core readiness. Vacuumlabs’ role is promising, but further review is needed. Project Catalyst is recommended to clarify deliverables. Signed: North American Community Hub
Would lean towards Catalyst, but deem this important enough to include in budget.
This proposal touches the core of global adoption — accessibility through language. Translating educational materials into local languages is not just outreach, it’s empowerment. I'd love to see clearer metrics for distribution impact and perhaps a collaboration with local educators or SPOs. Still, this is a powerful step toward a more inclusive ecosystem. Full support!
