"""Creates a signed P2PKH transaction and attempts to broadcast it on
the testnet blockchain. This accepts the same arguments as
:func:`~lit.PrivateKeyTestnet.create_transaction`.
:param outputs: A sequence of outputs you wish to send in the form
``(destination, amount, currency)``. The amount can
be either an int, float, or string as long as it is
a valid input to ``decimal.Decimal``. The currency
must be :ref:`supported <supported currencies>`.
:type outputs: ``list`` of ``tuple``
:param fee: The number of satoshi per byte to pay to miners. By default
Lit will poll `<https://bitcoinfees.earn.com>`_ and use a fee
that will allow your transaction to be confirmed as soon as
possible.
:type fee: ``int``
:param leftover: The destination that will receive any change from the
transaction. By default Lit will send any change to
the same address you sent from.
:type leftover: ``str``
:param combine: Whether or not Lit should use all available UTXOs to
make future transactions smaller and therefore reduce
fees. By default Lit will consolidate UTXOs.
:type combine: ``bool``
:param message: A message to include in the transaction. This will be
stored in the blockchain forever. Due to size limits,
each message will be stored in chunks of 40 bytes.
:type message: ``str``
:param unspents: The UTXOs to use as the inputs. By default Lit will
communicate with the testnet blockchain itself.
:type unspents: ``list`` of :class:`~bit.network.meta.Unspent`
:returns: The transaction ID.
:rtype: ``str``
