 NOTE: If no options are provided, the default gateway URL will be `https://swarm-gateways.net`. This means you don't necessarily need to [run your own Swarm node](https://swarm-guide.readthedocs.io/en/latest/gettingstarted.html), however there is an upload limit of ~2.5MB and no guarantees about permanence. It is recommended to run your own Swarm node.
