Use Cashu for the Lightning address and auto-sweep to self-custody when they fire up the app. Best of both worlds.

yeah its not a bad idea
Cashu is a nice idea, but it's more "moving parts". Like, now you have to worry about both your Lightning stuff breaking AND your cashu stuff breaking!
yes this has always been my thought. I just want something as simple as possible that works well.
Also -- about 6 weeks ago we did some network-wide testing of lightning addresses from dozens of different providers, and were able to measure payment latency & reliability of all the big players. (Down to the millisecond!) We're not publishing the results because the industry is not a stage where we want to make anyone look bad, but we learned a lot of interesting stuff that we're rolling into our new "free" Rizful wallet (coming soon.) If you're interested in the findings, pop me a DM.
Cashu kind of defies definition. It has a lot of moving parts ... when it does. But when it doesn't then it totally doesn't.
