impl<T, OU> OnChargeEVMTransaction<T> for OnChargeEVMTransaction<OU>
where T: Config, <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::PositiveImbalance: Imbalance<<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, Opposite = <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::NegativeImbalance>, <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::NegativeImbalance: Imbalance<<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, Opposite = <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::PositiveImbalance>, OU: OnUnbalanced<<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::NegativeImbalance>, U256: UniqueSaturatedInto<<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance>,

§

type LiquidityInfo = Option<<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::NegativeImbalance>

source§

fn withdraw_fee(who: &H160, fee: U256) -> Result<Self::LiquidityInfo, Error<T>>

Before the transaction is executed the payment of the transaction fees need to be secured.
source§

fn correct_and_deposit_fee( who: &H160, corrected_fee: U256, base_fee: U256, already_withdrawn: Self::LiquidityInfo ) -> Self::LiquidityInfo

After the transaction was executed the actual fee can be calculated. This function should refund any overpaid fees and optionally deposit the corrected amount, and handles the base fee rationing using the provided OnUnbalanced implementation. Returns the NegativeImbalance - if any - produced by the priority fee.
source§

fn pay_priority_fee(tip: Self::LiquidityInfo)

Introduced in EIP1559 to handle the priority tip.
