Changelog of the proposed runtime:

*   Add Ledger support, thanks to the Generic Ledger App [https://wiki.polkadot.network/docs/ledger](https://wiki.polkadot.network/docs/ledger)
*   One Token Model: Allows users to participate in funding rounds using one token only - such as USDC, USDT, or DOT
*   Allow transaction fee payment in DOT, USDt and USDC! Add XCM Runtime API to have a better cross-chain fee estimation

Authorize an upgrade to a given `code_hash` for the runtime. The runtime can be supplied
later.

The `check_version` parameter sets a boolean flag for whether or not the runtime's spec
version and name should be verified on upgrade. Since the authorization only has a hash,
it cannot actually perform the verification.

This call requires Root origin.

- **Problem Statement:** Simplifying participation in funding rounds and improving cross-chain fee estimation for users.

- **Proposed Solution:** Adding Ledger support, implementing a One Token Model, and enabling transaction fee payment in DOT, USDT, and USDC.
- **Expected Outcomes:** Streamlined funding participation, improved cross-chain fee estimation, and increased user convenience.
