Functions

func GetHtlc

func GetHtlc(hash lntypes.Hash, contract *loopdb.SwapContract,
	chainParams *chaincfg.Params) (*swap.Htlc, error)

GetHtlc composes and returns the on-chain swap script.

func GetHtlcScriptVersion

func GetHtlcScriptVersion(
	protocolVersion loopdb.ProtocolVersion) swap.ScriptVersion

GetHtlcScriptVersion returns the correct HTLC script version for the passed protocol version.

func MuSig2Sign

func MuSig2Sign(version input.MuSig2Version, privKeys []*btcec.PrivateKey,
	pubKeys []*btcec.PublicKey, tweaks *input.MuSig2Tweaks,
	msg [32]byte) ([]byte, error)

MuSig2Sign will create a MuSig2 signature for the passed message using the passed private keys.
