func (*FeeProvider) GetFeePerByte

func (fp *FeeProvider) GetFeePerByte(feeLevel wallet.FeeLevel) uint64

type FeeTargetInUSDCents

type FeeTargetInUSDCents float64

We will target a fee per byte such that it would equal 0.1 USD cent for economic, 1 USD cents for normal and 5 USD cents for priority for a median (226 byte) transaction.

const (
	EconomicTarget FeeTargetInUSDCents = 0.1
	NormalTarget   FeeTargetInUSDCents = 1
	PriorityTarget FeeTargetInUSDCents = 5

	AverageTransactionSize = 226
)

type Fees

type Fees struct {
	FastestFee  uint64
	HalfHourFee uint64
	HourFee     uint64
}
