I'm requesting a one-time retroactive tip to cover the costs for implementing several contributions that enable broader usage beyond transfers (locking, covering deposits) for assets in Asset Hub/Polkadot Hub. These contributions are either already released or in process of being merged for further release.

## Motivation

Three major contributions to the Polkadot-SDK in 2024, impacting Asset Hub.

- [#3951] (_already released_): 
    - Enables the basic support for _freezes_ (locks) using assets in Asset Hub.
- [#4530] (_already released_): 
    - Enables the basic support for _holds_ (deposits) using assets in Asset Hub.
    - Refactors the balances model (the way balances are calculated) for asset accounts to be in line with the way native token balances are calculated.
- [#7404] (_in final review_): Brings `pallet-vesting` to assets, so people can make vested transfers of (among others) stablecoins or tokens in Asset Hub. Made possible by [#3951].

In total, the measured amount for these contributions (measured in time spent, with a fixed hourly rate) is greater than the already compensated amount.

## Cost Breakdown

Measured amount: `$9,800` (with a rate of `$50/h`).

- Time spent in the three projects: `196h` (`~1.84 mo`)


Already compensated amount: `$2,224.346`

- 2 months of Fellowship salary: `$1,666.666`.
- Tip for [#3951]: `$557.68` (`80 DOT` at `$6.971/DOT` — EMA 7).

Remaining amount: `$7,575.654`
