Functions ¶

func AddConditionWitness ¶

func AddConditionWitness(inIndex int, ptx *psbt.Packet, witness wire.TxWitness) error

func AddCosignerKey ¶

func AddCosignerKey(inIndex int, ptx *psbt.Packet, key *btcec.PublicKey) error

func AddTaprootTree ¶

func AddTaprootTree(inIndex int, ptx *psbt.Packet, leaves []string) error

AddTaprootTree adds the whole taproot tree of the VTXO to the given PSBT input. it follows the format of PSBT_OUT_TAP_TREE / BIP-371

func AddVtxoTreeExpiry ¶

func AddVtxoTreeExpiry(
	inIndex int, ptx *psbt.Packet, vtxoTreeExpiry arklib.RelativeLocktime,
) error

func AnchorOutput ¶

func AnchorOutput() *wire.TxOut

func ExtractWithAnchors ¶

func ExtractWithAnchors(p *psbt.Packet) (*wire.MsgTx, error)

ExtractWithAnchors extracts the final witness and scriptSig from psbt fields and ignores anchor inputs without failing.

func FindAnchorOutpoint ¶

func FindAnchorOutpoint(tx *wire.MsgTx) (*wire.OutPoint, error)

func GetConditionWitness ¶

func GetConditionWitness(in psbt.PInput) (wire.TxWitness, error)

func GetCosignerKeys ¶

func GetCosignerKeys(in psbt.PInput) ([]*btcec.PublicKey, error)

func GetTaprootTree ¶

func GetTaprootTree(in psbt.PInput) ([]string, error)

GetTaprootTree returns the taproot tree of the given PSBT input.

func GetVtxoTreeExpiry ¶

func GetVtxoTreeExpiry(in psbt.PInput) (*arklib.RelativeLocktime, error)

func ReadTxWitness ¶

Types ¶

type TapTree ¶

type TapTree []string

TapTree is a wrapper around a list of tapscripts it is used to encode and decode the taproot tree in a way that is compatible with the PSBT_OUT_TAP_TREE field / BIP-371

func DecodeTapTree ¶

func DecodeTapTree(data []byte) (TapTree, error)

func (TapTree) Encode ¶

func (t TapTree) Encode() ([]byte, error)
