I saw everything but a wallet.
Safety? I don't know, since you don't own what you deposit.

Another negative thing I saw is that you need a phone number and email to register.
I saw more of a business than a wallet itself, although the "wallet exists".

I think they are more cons than pros.

And if you are looking for wallets I personally use and like Muun. Anyway investigate, I leave you a link to a list of Lightning wallets
