Rust API Client
A Rust library for connecting to Substrate-based blockchains via RPC, with a focus on no_std and embedded environments.
What is Rust API Client?
Substrate-api-client is a Rust library that provides an RPC client for connecting to and interacting with Substrate-based blockchain nodes. It allows developers to submit transactions, query on-chain state, and subscribe to events, specifically designed to work in resource-constrained no_std environments like trusted execution environments and embedded systems.
Rust developers building applications or services that need to interact with Substrate, Polkadot, or Kusama blockchains, particularly those working in embedded systems, TEEs, or other no_std environments.
It offers a simpler, more focused alternative to subxt with strong no_std support, making it the preferred choice for developers who need lightweight blockchain interaction in constrained environments without the overhead of a full-featured client.
