Namespace VHTLC

Virtual Hash Time Lock Contract (VHTLC) implementation.

VHTLC is a contract that enables atomic swaps and conditional payments in the Ark protocol. It provides multiple spending paths:

claim: Receiver can claim funds by revealing the preimage
refund: Sender and receiver can collaboratively refund
refundWithoutReceiver: Sender can refund after locktime expires
unilateralClaim: Receiver can claim unilaterally after delay
unilateralRefund: Sender and receiver can refund unilaterally after delay
unilateralRefundWithoutReceiver: Sender can refund unilaterally after delay

Example

const vhtlc = new VHTLC.Script({
  sender: alicePubKey,
  receiver: bobPubKey,
  server: serverPubKey,
  preimageHash: hash160(secret),
  refundLocktime: BigInt(chainTip + 10),
  unilateralClaimDelay: { type: 'blocks', value: 100n },
  unilateralRefundDelay: { type: 'blocks', value: 102n },
  unilateralRefundWithoutReceiverDelay: { type: 'blocks', value: 103n }
});
