FX is already available for External Wallet Access Mode integrations. See the External Wallet Access Mode FX flow for the current implementation with sequence diagrams.

How FX works

Users can instantly convert between fiat currencies they hold (e.g., USD to EUR). Behind the scenes, UR executes an atomic burn-and-mint operation on the user's tokenized deposits.
