A Common Ledger App Compatible With All Polkadot And Kusama Parachains [ retroactive funding for development ]
Dear Polkadot community,
We want to present you with a proposal for creating a common hardware (Ledger) wallet app unified to connect with all Polkadot and Kusama parachains.
As the ecosystem grows, it has become increasingly complex for users to manage their assets across various parachains securely. Currently, most parachains either implement their custom solutions and submit them to Ledger Live store themselves (max complexity level) or completely forgo the support for the hardware wallet.
This is where the proposed unified ledger app comes in. The app aims to simplify connecting hardware wallets, specifically Ledger, with the Polkadot ecosystem. This solution has the following advantages:
- New integration requires just a repository pool request
- No need to update the app on Ledger when new parachain integrates
- Polkadot/Substrate version upgrades don't require updating the app
- Supports both Polkadot and Kusama parachains
Recently, we have showcased a proof of concept of the app and made the first steps to set the ground for future developments. We've collected initial interest from parachain teams. Here is the list of projects who already submit PR for integration:
- Astar & Shiden
- HydraDX & Basilisk
- Zeitgeist
- Manta Network & Calamari
- Bifrost (DOT & KSM)
- Acala & Karura
- Nodle
- Origin Trail
- Ajuna Network & Bajun Network
- Bitgreen
- Crust (DOT & KSM)
Other things we've done so far:
- Set up a coordination group with Parity and teams (feel free to approach if you want to join)
- Validated the POC with Ledger
- Confirmed the scope of amendments to comply with the Ledger security audit
With this proposal, we seek retroactive funding to complete the app's development. By making it easier for users to manage their assets across various parachains, the unified ledger app will further enhance the usability and accessibility of the Polkadot ecosystem.

Manta Network supports this proposal, please use the treasury to truly support the ecosystem builders not those guys only make announcement of announcement and no one buy in
Nodle and myself fully support this proposal. The fragmentation among Ledger applications within the Polkadot ecosystem has traditionally been an important pain point - costs are prohibitive, and timelines with Ledger are obscure albeit with some recent improvements (and now costly too since we need to self-support the Ledger apps audits). Having a unified Ledger app for Polkadot will ensure most Parachain users can have access to high-security self-custody out of the box, and help parachains focus on higher ROI activities than maintaining a Ledger app and fighting with Ledger's obscure processes.
