The substrate-api-client is a Rust-library for connecting to a substrate-based node via RPC. It is an alternative to subxt, which provides a similar functionality. RPC clients are needed in any software component, connecting to a substrate parachain. Therefore it is advisable, that there is more than one client available for Rust developers. Apart from that, the substrate-api-client fills a gap, providing the possibility to create extrinsics in a no_std-environment. Thereby facilitating extrinsic creation from within trusted hardware (like Intel sgx). This has a big potential for further usage in IoT environments. Last but not least, the substrate-api-client has an easy-to-use interface and comes with many practical examples, which makes it a good option for new developers.

This proposal aims to fund:

1. maintenance and support for the substrate api client over 3 months (Nov-22 until Jan-23).

2. evaluation and design of two new features:
     - CLI-wallet implementation
     - full no_std-compatibility

See the [discussion](https://kusama.polkassembly.io/post/1923) and our [full proposal](https://docs.google.com/document/d/1miIIMyHsNzdoZejVdBiV_u3NLyj7CHsr9uWBdKonrtQ/edit?usp=sharing) for the details.


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.
