Thanks, but I feel like I'm missing something...as I understand it to receive zaps you want or need a persistent lightning address, not an invoice that expires, and LNURL accomplishes this? But it seems the only custodial options (for a beginner here) are primal and alby, and both require personal information 

 Correct. Every single wallet included above has a Lightning address. 

 oh awesome thanks! I guess all the ones I tried so far don't have an LNURL (tried phoenix, blue wallet, muun)
