'''
Creates atomic swap unsigned transaction object.
Args:
sender_address (str): wallet address of the sender
recipient_address (str): wallet address of the recipient
value (float): amount to swap
solvable_utxo (list): optional list of UTXO objects. If None then it will try to find UTXO automatically
by using the `get_utxo` method.
secret_hash (str): optional secret hash to be used in transaction. If None then the new hash
will be generated.
Returns:
BitcoinAtomicSwapTransaction, None: unsigned Atomic Swap transaction object or None if something went wrong
Example:
>>> from clove.network import BitcoinTestNet
>>> network = BitcoinTestNet()
>>> network.atomic_swap('msJ2ucZ2NDhpVzsiNE5mGUFzqFDggjBVTM', 'mmJtKA92Mxqfi3XdyGReza69GjhkwAcBN1', 2.4)
