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 the process of being merged for further release.

## Motivation

In the last year, I made three major contributions to the Polkadot SDK, which impact the user experience of Asset Hub/Polkadot Hub.

- [#3951] (_already released_): 
    - Provides basic support for _freezes_ (_locks_) using assets in the Asset Hub. This enables the possibility, among others, of vesting assets ([#7404]).
- [#4530] (_already released_): 
    - Provides basic support for holds (deposits) using assets in the Asset Hub. This is connected to an upcoming project to determine which asset to use for paying deposits (utilising a conversion model) when signing a transaction, or even paying for deposits using stablecoins or ETH across the bridge.
    - 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) exceeds 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`

- A developer contributed to Polkadot SDK, improving Asset Hub features.  
- Added support for freezing assets (like locks) and handling deposits.  
- Made balance calculations for assets match native tokens.  
- Working on vested transfers for stablecoins.  
- Spent 196 hours (about 1.84 months) on these projects.  
- Already received $2,224.34 in compensation.  
- Requests $7,575.65 to cover remaining work costs.  
- Contributions help users manage assets better.
