§Skip Feeless Payment Pallet
This pallet allows runtimes that include it to skip payment of transaction fees for
dispatchables marked by [#[pallet::feeless_if]
](macro@ frame_support::pallet_prelude::feeless_if
).
§Overview
It does this by wrapping an existing SignedExtension
implementation (e.g.
[pallet-transaction-payment
]) and checking if the dispatchable is feeless before applying the
wrapped extension. If the dispatchable is indeed feeless, the extension is skipped and a custom
event is emitted instead. Otherwise, the extension is applied as usual.
§Integration
This pallet wraps an existing transaction payment pallet. This means you should both pallets
in your construct_runtime
macro and include this pallet’s
SignedExtension
(SkipCheckIfFeeless
) that would accept the existing one as an argument.
