Constants ¶
const ( // ChainInternal internal chain num ChainInternal = uint32(1) // ChainExternal external chain num ChainExternal = uint32(0) )
const ScriptHashType = "scripthash"
ScriptHashType is the type for the deprecated script hash
const ScriptMetanet = "metanet"
ScriptMetanet is the type for a metanet transaction
const ScriptTypeMultiSig = bscript2.ScriptTypeMultiSig
ScriptTypeMultiSig alias from bscript
const ScriptTypeNonStandard = bscript2.ScriptTypeNonStandard
ScriptTypeNonStandard alias from bscript
const ScriptTypeNullData = bscript2.ScriptTypeNullData
ScriptTypeNullData alias from bscript
const ScriptTypePubKeyHash = bscript2.ScriptTypePubKeyHash
ScriptTypePubKeyHash alias from bscript
Variables ¶
var ErrDeriveFailed = errors.New("derive addresses failed, missing addresses")
ErrDeriveFailed is when the address derivation failed
var ErrHDKeyNil = errors.New("hd key is nil")
ErrHDKeyNil is when the HD Key is nil
var ErrXpubInvalidLength = errors.New("xpub is an invalid length")
ErrXpubInvalidLength is when the length of the xpub does not match the desired length
var ErrXpubNoMatch = errors.New("xpub key does not match raw key")
ErrXpubNoMatch is when the derived xpub key does not match the key given
Functions ¶
func DeriveAddresses ¶
func DeriveAddresses(hdKey *bip32.ExtendedKey, num uint32) (external, internal string, err error)
DeriveAddresses will derive the internal and external address from a key
func DeriveChildKeyFromHex ¶
func DeriveChildKeyFromHex(hdKey *bip32.ExtendedKey, hexHash string) (*bip32.ExtendedKey, error)
DeriveChildKeyFromHex derive the child extended key from the hex string
func DerivePrivateKeyFromHex ¶
func DerivePrivateKeyFromHex(hdKey *bip32.ExtendedKey, hexString string) (*bec.PrivateKey, error)
DerivePrivateKeyFromHex will derive the private key from the extended key using the hex as the derivation paths
func DerivePublicKey ¶
DerivePublicKey will derive the internal and external address from a key
func DerivePublicKeyFromHex ¶
DerivePublicKeyFromHex will derive the public key from the extended key using the hex as the derivation paths
func GetChildNumsFromHex ¶
GetChildNumsFromHex get an array of uint32 numbers from the hex string
func GetDestinationType ¶
GetDestinationType Get the type of output script destination
func GetInputSizeForType ¶
GetInputSizeForType get an estimated size for the input based on the type
func GetModelBoolAttribute ¶
GetModelBoolAttribute the attribute from the model as a bool
func GetModelName ¶
func GetModelName(model interface{}) *string
GetModelName get the name of the model via reflection
func GetModelStringAttribute ¶
GetModelStringAttribute the attribute from the model as a string
func GetModelTableName ¶
func GetModelTableName(model interface{}) *string
GetModelTableName get the db table name of the model via reflection
func GetModelType ¶
GetModelType get the model type of the model interface via reflection
func GetModelUnset ¶
GetModelUnset gets any empty values on the model and makes sure the update actually unsets those values in the database, otherwise this never happens, and we cannot unset
func GetOutputSize ¶
GetOutputSize get an estimated size for the output based on the type
func GetTransactionIDFromHex ¶
GetTransactionIDFromHex get the transaction ID from the given transaction hex
func IsModelSlice ¶
func IsModelSlice(model interface{}) bool

func IsOpReturn ¶
IsOpReturn Check whether the given string is an op_return
func MarshalNullString ¶
func MarshalNullString(x NullString) graphql.Marshaler
MarshalNullString is used by graphql to marshal into a string
func MarshalNullTime ¶
