Crate pallet_whitelist 

Whitelist Pallet

• Config
• Call

Overview

Allow some configurable origin: Config::WhitelistOrigin to whitelist some hash of a call, and allow another configurable origin: Config::DispatchWhitelistedOrigin to dispatch them with the root origin.

In the meantime the call corresponding to the hash must have been submitted to the pre-image handler pallet::Config::Preimages.

Deferred dispatch

A dispatch by Config::DispatchWhitelistedOrigin of a not-yet-whitelisted hash is deferred into DeferredDispatch with an expiration. Once the hash is whitelisted, any signed account can relay it as root, fee-free.

WhitelistedCall and DeferredDispatch are independent: each is written only by its own origin and neither removes the other. Unwhitelisting therefore pauses a live deferral rather than cancelling it. Relayers are blocked while the hash is off the whitelist, but re-whitelisting it before expiry re-enables relayed execution without a new governance act.
