FPI Controller Pool

Description

The FPI Controller Pool has various helper functions related to FPI and its peg.

Mint / Redeeming

Users can mint FPI with FRAX or redeem FPI for FRAX. There is a small fee associated with this, initially 0.30%.

twammToPeg

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.

giveFRAXToAMO / receiveFRAXFromAMO

The contract can lend FRAX collateral to various AMOs that earn yield (among other things).
