func (DeductGrantedFeeDecorator) AnteHandle ¶
func (d DeductGrantedFeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)
AnteHandle performs a decorated ante-handler responsible for deducting transaction fees. Fees will be deducted from the account designated by the FeePayer on a transaction by default. However, if the fee payer differs from the transaction signer, the handler will check if a fee grant has been authorized. If the transaction's signer does not exist, it will be created.
