Precious Metals work just like another currency within the Revolut ecosystem :
You can send Precious Metals exposure to a friend on Revolut who has this feature enabled:
Tap on the 'Payments' tab in the app. Select from your contact list one of those with an 'R' next to their name and tap ‘Send’. Enter the amount you would like to send, choose XAU or XAG from the drop-down list and tap ‘Send’ again. The Precious Metals exposure will appear immediately in their Revolut account! Please note that currently, we do not support transferring Precious Metals exposure to accounts outside of the Revolut platform, e.g. to an external Precious Metals account.
You can use pretty much all of the Revolut features :
Vaults, cashback, spare change round-up, auto-exchanges, you name it! Precious Metals work just like another currency within the Revolut ecosystem.
