We'd like to fund maintenance of the [substrate-api-client](https://github.com/scs/substrate-api-client) from August 2023 until October 2023.

The [substrate-api-client](https://github.com/scs/substrate-api-client) is a Rust library for connecting to a substrate-based node via RPC in a no-std environment. An RPC client is a library, with similar features as [Polkadot-js](https://wiki.polkadot.network/docs/polkadotjs). With an RPC client developers can easily interact with any Polkadot or Kusama chain. There are [RPC clients](https://wiki.polkadot.network/docs/build-tools-index#rpc-and-api-tools) for different programming languages. For Rust, the most popular RPC client is [subxt](https://github.com/paritytech/subxt). Subxt uses the Rust standard library (std). The Rust standard library is not available in certain environments, such as trusted execution environments (like IntelSGX) or certain IoT devices. The substrate-api-client bridges this gap,  providing a library that can be used in such environments.

This proposal is a continuation of our previous maintenance proposals: [Nov22-Jan23](https://kusama.polkassembly.io/referenda/26), [Feb23-Apr23](https://kusama.polkassembly.io/referenda/88), [May23-Jul23](https://kusama.polkassembly.io/referenda/182). See also our reports in the comments section of each proposal. We aim to seek ongoing funding.

Maintenance for the substrate-api-client Aug-23 to Oct-23

Treasury

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.

- They want to fund maintenance of a Rust library called substrate-api-client.
- The library helps connect to a substrate-based node via RPC.
- RPC clients are used to interact with Polkadot or Kusama chains.
- The library is useful in environments where the Rust standard library is not available.
- This is a continuation of previous maintenance proposals and they are seeking ongoing funding.
