Registration in a country with not-listed currency

It is not clear to me whether it is possible to send money to a revolut user in a country with a currency not (yet) listed, say Perù (PEN).
Assuming he/she will be able to signup.

There could be a workaround using a USD account in that country, in that case one could send USD.
But my question is first of all about availability of Revolut in a country not listed…thanx

You can send funds to an already existing Revolut user via the app. If that person is not a resident of an EEA country then they are breaking the terms and agreement. In any case you can do a normal swift transfer to a person i PERU instead.
