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.

A Common Ledger App Compatible With All Polkadot And Kusama Parachains [ retroactive funding for development ]

Propose and approve a spend of treasury funds.

- `origin`: Must be `SpendOrigin` with the `Success` value being at least `amount`.
- `amount`: The amount to be transferred from the treasury to the `beneficiary`.
- `beneficiary`: The destination account for the transfer.

NOTE: For record-keeping purposes, the proposer is deemed to be equivalent to the
beneficiary.
