I haven't figured out how to do lightning with self-custody BTC yet.  I am willing to have a custodial lightning wallet - as long as I can limit the BTC at risk and keep the BTC myself.   Actually running a lightning node myself seems to have requirements that are not worth the small amount of BTC at risk.  Is it possible to have a self-custody wallet with someone else's node?  How does the node operator get paid?  

I read up a bit more each week.
