To start, our most basic level of the swap, regular swapping with HP and Tax check, and preset gas and gwei, will always have 0 fees and require no holdings!
Anyone can now use any tier they please for a fee in ETH on each trade. If you are tier 0 and you use a tier 1 feature, you will be charged the fee in ETH! Same goes for tier 1 using tier 2 etc. The fees are used to reward all of the stakers in the project.
Fees are currently set to 4% but are able to be lowered as time goes on. The goal of the fees is to bring in just enough to cover the weekly staking reward pool.
