I use my own BTCPay server if you wanna help thr stats.
Ran some analytics on zaps on nostr, it's quite terrible...
~95% of users have their lightning address set to a custodial wallet
~91% of all zaps by volume have gone to a custodial wallet
#[0] is the clear winner of 50% of users and 67.5% of volume

I want to but...

I got 2 zaps a few minutes ago but you are right, I had a problem with my nodd, I couldn't pay for my burger with Bitcoin LN this lunch, my node gavean error twice. Maybe I'm under DoDS attack somehow?
No wonder why most use custodial in that case.
Thanks for trying to zap anyway.
Worked now ⚡
It was me, glad it worked. Zapped twice because the first one Zeus told me that the payment failed so I tried again then both succeeded.
Now I have to try a setup like yours. I was going to wait for Bolt12 but let's experiment a bit until it comes.
Thanks, good luck with your experiment. Do plan to use RaspBlitz, Umbrel (or fork), Elementary OS or install all manually?
