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

Zondax team, known for maintaining Ledger apps for Polkadot, Kusama, Statemine, and Statemint, seeks funding from the treasury to continue their services. Their Ledger apps provide secure interaction with substrate chains using Ledger devices. The proposal includes ongoing maintenance, bug fixes, security audits, and project management for these Ledger apps. The budget covers development costs and third-party security audits, ensuring continuous compatibility and security.

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

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.
