To send cryptocurrency to a friend on Revolut, tap on the 'Payments' tab in the app and select one of your Revolut friends. Next, enter the amount you would like to send, choose cryptocurrency from the drop-down list, and then tap 'Send' and crypto will appear instantly in their Revolut account!
You will not be able to transfer cryptocurrency to outside the Revolut platform, e.g. external wallets. We are actively working on bringing this functionality to you in the future. However, you can still buy, sell and exchange within the Revolut platform.
