Uniswap has changed the fees for ETH/USDC to be calculated separately for each side! The VolatilePair Hook, launching on Ethereum mainnet on October 14, will calculate fees for buys and sells based on recent price changes. After sharp price movements, trades that push the pool price back may even temporarily incur an extra layer of fees. This design aims to leave more value for LPs, but dynamic fees don’t necessarily mean every trade will be cheaper. Traders need to consider direction and timing, while LPs should focus on actual fee income and price risk. Whether this mechanism works well or not, let the trading data speak for itself.
