The Rari Capital robo-advisor has a few set of fees for the protocol, including a performance fee and a withdrawal fee. There is also a time-based transfer fee for early $RGT transfers.
These fees power Rari's revenue and are generated from the Rari protocol on the following occasions:
Stable Pool: 17.5% profits
Yield Pool: 12.5% profits + 0.5% withdrawal
(The withdrawal fee is required to prevent arbitrage within this pool since it is composed of various stablecoins which may have minor price fluctuations)
ETH Pool: 17.5% of profits
RIP-3 updated our fee structure to be as seen above.
These fees are then entered as Protocol Revenues which you can read more about here.
