Functions

func EstimateSerializeSize 

func EstimateSerializeSize(inputCount int, txOuts []*wire.TxOut, addChangeOutput bool, inputType InputType) int

EstimateSerializeSize returns a worst case serialize size estimate for a signed transaction that spends inputCount number of compressed P2PKH outputs and contains each transaction output from txOuts. The estimated size is incremented for an additional P2PKH change output if addChangeOutput is true.

func NormalizeCurrencyCode 

func NormalizeCurrencyCode(currencyCode string) string

NormalizeCurrencyCode standardizes the format for the given currency code

func SumOutputSerializeSizes 

func SumOutputSerializeSizes(outputs []*wire.TxOut) (serializeSize int)

SumOutputSerializeSizes sums up the serialized size of the supplied outputs.
