FPI Controller Pool
The FPI Controller Pool has various helper functions related to FPI and its peg.
Users can mint FPI with FRAX or redeem FPI for FRAX. There is a small fee associated with this, initially 0.30%.
The twammToPeg function is used by the protocol to introduce market pressure to bring the market price of FPI up (or down) to the target peg price.
The contract can lend FRAX collateral to various AMOs that earn yield (among other things).
