chain

This section introduces the core chain modules of the CESS Rust SDK. Each module corresponds to a specific on-chain pallet and provides both query and transaction interfaces to interact with the CESS blockchain.

These modules enable you to fetch chain state, submit transactions, and manage storage, files, and operational logic across the network.
