17//! Bridge definitions that can be used by multiple BridgeHub flavors.
18//! All configurations here should be dedicated to a single chain; in other words, we don't need two
19//! chains for a single pallet configuration.
20//!
21//! For example, the messaging pallet needs to know the sending and receiving chains, but the
22//! GRANDPA tracking pallet only needs to be aware of one chain.
