defmodule BSV.Contract.Raw do
  @moduledoc """
  The Raw Script contract provides a mechanism through which pre-built scripts
  can be used with the `BSV.TxBuilder` module.

  ## Examples

      iex> builder = %TxBuilder{
      ...>   outputs: [
      ...>     Raw.lock(10_000, %{script: Script.from_binary!(@p2pkh_hex, encoding: :hex)})
      ...>   ]
      ...> }
      iex> TxBuilder.to_tx(builder)
      %BSV.Tx{
        inputs: [],
        outputs: [
          %BSV.TxOut{
            satoshis: 10000,
