Lightning Addresses: A Non-Custodial Payment

The main challenge in supporting lightning addresses in a non-custodial environment is the ability to receive offline. The reason that Breeze, for example, the Breeze app currently doesn't support lightning addresses is because we don't have a reliable way to send users funds when they're offline. So I would say stackless payments is important. Asynchronyous payments for me, it's a top priority. And improving payment reliability is something that is constantly being researched and being improved.
