When i signed up on iphone it was "kyc" as in there was a name field, and an email address field, and as long as I entered something it let me continue.
Also it wants to know what country you are in for some reason
This is scary. What happens if they freeze your wallet one day because your KYC is incomplete/fake?
I would never keep more than 25,000 sats (currently less that $5usd) in any custodial wallet so I’m not overly concerned.
I transfer anything over that to my non custodial wallet. (And generally not more than 250k sats in lightning period)
