Summary:
Proposed by JS of the mStable Core team to allow users to pay for swap fees using MTA and give them a 50% discount for doing so.
Abstract:
The fees could be moved into two places, either burned out of circulation or sold for bASSET to bolster APY.
Burning MTA would be easier to implement and reduces supply for MTA, which is good for MTA price and good for system security once recollateralisation is up
Negatives include reducing the APY for savers and moves away from the model where SAVE is the end goal
