I talked to a guy from them at BTC Prague.

1) They are regulated under El Salvador law

2) The law requires and identifier, but does not specify what is shall be

3) Phone number for convince

4) Somehow you can create account just with an email (I think is somehow hidden under demo account

5) They will use the ID of the Android or something (probably works only on Android)

However, if you are on GrapheneOS they will block it, as this ID is changed every time cos' GrapheneOS does good job.

I tried many online SMS gates (even paid). None worked.

Maybe there is some, but I lost m interestet.

They simp for government, so they are irrelevant for me.
