Do you charge processing fees for flash loans ?
yes, very small fees for each flash loan, that will go in big part to the liquidity providers of the specific asset
Does that mean the income for liquidity provider are generated only from the loan fee? Is there no interest for each loan that the borrower has to pay?
There is no interest for the flash loan that the borrower has to pay
The income for Liquidity Provider is coming from loan fees plus yield farming (receiving EQZ governance tokens, the longer he farms the higher the APY)
