It's one of the best, non custodial #Bitcoin LN wallets out there, IMO. That's why I'm asking nostr:npub1s8a9ku988f53cmncsg7sxhlugnmt2p0x7qmrwavm6dh853g4887ss69u5q, perhaps I'm missing something.

I don't think I've ever paid high fees anywhere on LN. The only time high fees occurs is when opening or closing a channel.
