httpx.post(api_base_url + "/txs", data=pushable_tx)One or more token transfers can be added to a transaction by calling the add_transfer method.
When the transaction is fully prepared, calling get_pushable will return a signed transaction in the form of a JSON string.
This can be used as request body when calling the POST /txs endpoint of the Cosmos REST API.
