Subxt is a Rust library that allows developers to interact with Substrate-based blockchain nodes using Rust or WebAssembly. It is intended for blockchain developers who need to programmatically connect, query, and interact with Substrate blockchains—such as Polkadot or custom chains built on Substrate—in a type-safe manner. Subxt provides convenient APIs for transactions, queries, and decoding blockchain data.
