Thanks Nathan - if you are ok with follow up questions,
1) how to know which wallet has NIP 57?
I know WoS, Alby, Lightining TipBot, Zeus works based on users who have mentioned it on Nostr (i use the first 2) - how about the rest?
2) on LN Auth - so it determines custodial (3rd party with info) vs non-custodial ?
