fee_filters.rs

//! Extrinsics whose transaction fee is charged to the signing hotkey's owning
//! coldkey instead of the hotkey itself. Every entry resolves its signed origin as
//! a hotkey; the coldkey is charged only when that hotkey has an owner, otherwise
//! the signer pays (see [`ColdkeyFeeCallFilter`]). Extend one line per extrinsic as
//! more hotkey-origin calls are opted in.
