//! Create and submit extrinsics.
//!
//! An extrinsic is submitted with an "signed extra" and "additional" parameters, which can be
//! different for each chain. The trait [`crate::config::ExtrinsicParams`] determines exactly which
//! additional and signed extra parameters are used when constructing an extrinsic, and is a part
//! of the chain configuration (see [`crate::config::Config`]).
// The PairSigner impl currently relies on Substrate bits and pieces, so make it an optional
// feature if we want to avoid needing sp_core and sp_runtime.
