    • redeemP2WSH

      public static TransactionWitness redeemP2WSH(Script witnessScript, TransactionSignature... signatures)
      Creates the stack pushes necessary to redeem a P2WSH output.

    • of

      public static TransactionWitness of(List<byte[]> pushes)
      Construct a transaction witness from a given list of arbitrary pushes.
      Parameters:
      pushes - list of pushes
      Returns:
      constructed transaction witness

    • of

      public static TransactionWitness of(byte[]... pushes)
      Construct a transaction witness from a given list of arbitrary pushes.
      Parameters:
      pushes - list of pushes
