FRAX protocol buys back $ millions of FXS every month with its profits from its AMO’s
The funds being used to fund lending AMOs are not from an influx of cash. FRAX is minted in to the lending pool its then lent out, the people that borrow it put up collateral to back their loan (normally over -collateralized) and that is then used to back the FRAX they borrowed. The more people borrow , the more interest they pay and the more profit the FRAX protocol makes and the more FXS it buys back with that profit.
i understand the FRAX UI is not the simplest but as the team have said “its not built for grandma” . and there is already a proposal to build a second UI > Frax.Pro Website
