//! # Subxt-signer
//!
//! The main output from this crate is the [`sr25519::Keypair`], which can
//! be constructed from a bip39 phrase, secret URI or raw seed, and used to
//! sign and verify arbitrary messages. This crate is aligned with how Substrate's
//! `sp_core` crate constructs and signs keypairs, but is lighter on dependencies
//! and can support compilation to WASM with the `web` feature.
//!
//! Enable the `subxt` feature to enable use of this [`sr25519::Keypair`] in signing
//! subxt transactions for chains supporting sr25519 signatures.
