Substrate-api-client is a Rust-library that helps connect to a substrate-based node via RPC.
It is an alternative to subxt, which provides similar functionality.
It fills a gap by allowing the creation of extrinsics in a no_std-environment, which is useful for trusted hardware like Intel sgx.
It has an easy-to-use interface and comes with many practical examples, making it a good option for new developers.
The proposal aims to fund maintenance and support for the substrate api client over 3 months and the evaluation and design of two new features: CLI-wallet implementation and full no_std-compatibility.
