//! Parachain compatibility for the template wallet.
//!
//! The wallet is not intended to support a wide variety of chains, but it is able
//! to support both the sovereign and parachain template nodes. There are a few types
//! necessary to make this work.
//!
//! We don't want the wallet to depend on the parachain runtime which has a huge
//! dependency graph itself. So a few types are duplicated here.
