Fees are taken from yield generated (on compounding/when the strategy runs), but there are no fees on principal deposits. Fees are liable to vary in the future, depending on the platform's demands, and are accumulated in the treasury.
FULLDAO will take 6% of the Harvest rewards when users deposit in Vaults as fee.
FULLDAO Fee = 6% = x + y + z
x = 1.5% : platform fee
y = 1% : used to rewards AVAX to TOP users (based on their allocation points or NFT levels)
