5//! The "default" Substrate/Polkadot Address type. This is used in codegen, as well as signing related bits.
6//! This doesn't contain much functionality itself, but is easy to convert to/from an `sp_runtime::MultiAddress`
7//! for instance, to gain functionality without forcing a dependency on Substrate crates here.

13/// functionality is provided via `From` impls if the `substrate-compat` feature is enabled).
