Functions

func Address

func Address(params *dagconfig.Params, extendedPublicKeys []string, minimumSignatures uint32, path string, ecdsa bool) (util.Address, error)

Address returns the address associated with the given public keys and minimum signatures parameters.

func CreateKeyPair

func CreateKeyPair(ecdsa bool) ([]byte, []byte, error)

CreateKeyPair generates a private-public key pair

func CreateMnemonic

func CreateMnemonic() (string, error)

CreateMnemonic creates a new bip-39 compatible mnemonic

func CreateUnsignedTransaction

func CreateUnsignedTransaction(
	extendedPublicKeys []string,
	minimumSignatures uint32,
	payments []*Payment,
	selectedUTXOs []*UTXO) ([]byte, error)

CreateUnsignedTransaction creates an unsigned transaction

func ExtractTransaction

func ExtractTransaction(partiallySignedTransactionBytes []byte, ecdsa bool) (*externalapi.DomainTransaction, error)

ExtractTransaction extracts a domain transaction from partially signed transaction after all of the relevant parties have signed it.

func IsTransactionFullySigned

func IsTransactionFullySigned(partiallySignedTransactionBytes []byte) (bool, error)

IsTransactionFullySigned returns whether the transaction is fully signed and ready to broadcast.

func MasterPublicKeyFromMnemonic

func MasterPublicKeyFromMnemonic(params *dagconfig.Params, mnemonic string, isMultisig bool) (string, error)

MasterPublicKeyFromMnemonic returns the master public key with the correct derivation for the given mnemonic.

func MinimumCosignerIndex

func MinimumCosignerIndex(cosignerExtendedPublicKeys, allExtendedPublicKeys []string) (uint32, error)

MinimumCosignerIndex returns the minimum index for the cosigner from the set of all extended public keys.

func PublicKeyFromPrivateKey

func PublicKeyFromPrivateKey(privateKeyBytes []byte) ([]byte, error)

PublicKeyFromPrivateKey returns the public key associated with a private key

func Sign

func Sign(params *dagconfig.Params, mnemonics []string, serializedPSTx []byte, ecdsa bool) ([]byte, error)

Sign signs the transaction with the given private keys

Types

type Payment

type Payment struct {
	Address util.Address
	Amount  uint64
}

Payment contains a recipient payment details

type UTXO

type UTXO struct {
	Outpoint       *externalapi.DomainOutpoint
	UTXOEntry      externalapi.UTXOEntry
	DerivationPath string
}

UTXO is a type that stores a UTXO and meta data that is needed in order to sign it and create transactions with it.
