I present my proposal to you again, but with a slight adjustment. I suggest that you modify the fee that I initially proposed to you, setting it at 0.5%. However, if the PEG in the main DEXs with the most liquidity, like Minswap, is below or above 5%, this fee could increase up to 3%. Each increase would be staggered by 0.5% for every 5% that deviates from the PEG in the DEXs. For example:
When requesting iUSD, the fees in ADA would be as follows:
If iUSD is worth 0.97 USD, the fee when requesting a CDP would be 0.5% (base fee). If iUSD is worth 0.94 USD, the fee would increase to 1%. If iUSD is worth 0.89 USD, the fee would rise to 1.5%. When burning iUSD, the fees would be as follows:
If iUSD is worth 1.051 USD (a problem you will also face), the fee when burning would be 1%.
If iUSD is worth 1.35, the fee would increase up to 3%, which would be the fee limit. Remember that the accumulated fees of ADA and iUSD are allocated to the stability pool. To have more stable fees, they could be adjusted in each Cardano epoch. Because if the value is below 0.8 for just one minute, such fees should not be charged. Again, the idea is to maintain the base fee at 0.5%
