Do you need DEXA for FRAX?

Excuse me, could you please elaborate on the necessity of DEXA for FRAX? I've been hearing a lot about the integration between these two cryptocurrencies but I'm still unclear on the specifics. Is DEXA a crucial component for FRAX's functionality? Or is it more of a complementary asset that provides additional benefits? I'm particularly interested in understanding if investors or users of FRAX need to hold or utilize DEXA in order to fully leverage the benefits of FRAX. Clarifying this relationship would greatly assist me in making informed decisions regarding my cryptocurrency portfolio. Thank you for your time and consideration.
