func GenerateMultiAddress 

func GenerateMultiAddress(redeemScript []byte, net *chaincfg.Params) (string, error)

func GenerateSignedBuyingTx 

func GenerateSignedBuyingTx(ins []*TxInput, outs []*TxOutput, sellerPsbt string, network *chaincfg.Params) (string, error)

func GenerateSignedListingPSBTBase64 

func GenerateSignedListingPSBTBase64(in *TxInput, out *TxOutput, network *chaincfg.Params) (string, error)

func GenerateUnsignedPSBTHex 

func GenerateUnsignedPSBTHex(ins []*TxInput, outs []*TxOutput, network *chaincfg.Params) (string, error)

func GetRedeemScript 

func GetRedeemScript(pubKeys []string, minSignNum int) ([]byte, error)

func GetTransactionWeight 

func GetTransactionWeight(tx *btcutil.Tx) int64

GetTransactionWeight computes the value of the weight metric for a given transaction. Currently the weight metric is simply the sum of the transactions's serialized size without any witness data scaled proportionally by the WitnessScaleFactor, and the transaction's serialized size including any witness data.

func GetTxHex 

func GetTxHex(tx *wire.MsgTx) (string, error)

func GetTxVirtualSize 

func GetTxVirtualSize(tx *btcutil.Tx) int64

GetTxVirtualSize computes the virtual size of a given transaction. A transaction's virtual size is based off its weight, creating a discount for any witness data it contains, proportional to the current blockchain.WitnessScaleFactor value.

func MultiSignBuild 

func MultiSignBuild(tx *wire.MsgTx, priKeyList []string) (string, error)

func NewTxFromHex 

func NewTxFromHex(txHex string) (*wire.MsgTx, error)

func PayToPubKeyHashScript 

func PayToPubKeyHashScript(pubKeyHash []byte) ([]byte, error)

func PayToWitnessPubKeyHashScript 

func PayToWitnessPubKeyHashScript(pubKeyHash []byte) ([]byte, error)

func PubKeyToAddr 

func PubKeyToAddr(publicKey []byte, addrType string, network *chaincfg.Params) (string, error)

func Sign 

func Sign(tx *wire.MsgTx, privateKeys []*btcec.PrivateKey, prevOutFetcher *txscript.MultiPrevOutFetcher) error

func SignTx 

func SignTx(raw string, pubKeyMap map[int]string, signatureMap map[int]string) (string, error)
