The team has a solid track record with ongoing maintenance, and continued funding will keep this essential tool up-to-date.

We'd like to fund maintenance of the [substrate-api-client](https://github.com/scs/substrate-api-client) from July 2024 until December 2024.

The [substrate-api-client](https://github.com/scs/substrate-api-client) is a Rust library for connecting to a substrate-based node via RPC from a no-std environment, like trusted execution environments or IoT devices. 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). The substrate-api-client uses core functionality of subxt and makes it available in a no-std environment.

This proposal is a continuation of our previous maintenance proposals. The previous proposal can be found [here](https://polkadot.polkassembly.io/treasury/546). See also our reports in the comments section of each proposal. We aim to seek ongoing funding.

### Substrate-API-Client Maintenance Proposal

- **Project**: Maintenance of the [substrate-api-client](https://github.com/scs/substrate-api-client) Rust library.
- **Duration**: July 2024 to December 2024.
- **Purpose**: Connect to substrate-based nodes via RPC from no-std environments like trusted execution environments or IoT devices.
- **Features**: Similar to [Polkadot-js](https://wiki.polkadot.network/docs/polkadotjs), allowing easy interaction with Polkadot or Kusama chains.
- **Comparison**: Competes with [subxt](https://github.com/paritytech/subxt), a popular Rust RPC client, but focuses on no-std environments.
- **Previous Work**: Continuation of previous maintenance proposals, with reports available in comments sections.
- **Funding Request**: $33,300.
- **Full Proposal**: Detailed information available [here](https://docs.google.com/document/d/1vaB6NL5qTrOFH4gIbYyfqwB_JL3MhpOgcJhPmzKGrxY/edit?usp=sharing).
