Types

type Sweeper

type Sweeper struct {
	Lnd *lndclient.LndServices
}

Sweeper creates htlc sweep txes.

func (*Sweeper) CreateSweepTx

func (s *Sweeper) CreateSweepTx(
	globalCtx context.Context, height int32,
	htlc *swap.Htlc, htlcOutpoint wire.OutPoint,
	keyBytes [33]byte,
	witnessFunc func(sig []byte) (wire.TxWitness, error),
	amount, fee btcutil.Amount,
	destAddr btcutil.Address) (*wire.MsgTx, error)

CreateSweepTx creates an htlc sweep tx.

func (*Sweeper) GetSweepFee

func (s *Sweeper) GetSweepFee(ctx context.Context,
	addInputEstimate func(*input.TxWeightEstimator),
	destAddr btcutil.Address, sweepConfTarget int32) (
	btcutil.Amount, error)

GetSweepFee calculates the required tx fee to spend to P2WKH. It takes a function that is expected to add the weight of the input to the weight estimator.
