Uniswap will charge a fixed fee of 0.15% for 11 types of tokens traded through the official front-end.
According to an official announcement from BlockBeats on October 17th, Uniswap will begin charging a 0.15% exchange fee for certain tokens in its web application and wallet, including ETH, USDC, WETH, USDT, DAI, WBTC, agEUR, GUSD, LUSD, EUROC, and XSGD. The fee will only be charged for exchange transactions where both the buying and selling tokens are subject to the fee, and will only apply to transactions conducted through the Uniswap Labs interface on the mainnet and L2. Exchange transactions between stablecoins are not included in this fee, nor are wrapped transactions between ETH and WETH. Uniswap has stated that this fee is separate from the Uniswap protocol fee switch, which is determined by governance vote. Uniswap Labs is committed to providing a simple and transparent pricing strategy.
