Struct pallet_frequency_tx_payment::ChargeFrqTransactionPayment

pub struct ChargeFrqTransactionPayment<T: Config>(/* private fields */);

Require the transactor pay for themselves and maybe include a tip to gain additional priority in the queue.

Transaction Validity

This extension sets the priority field of TransactionValidity depending on the amount of tip being paid per weight unit.

Operational transactions will receive an additional priority bump, so that they are normally considered before regular transactions.
