UniswapX Unleashed: Can Zero-Gas Transactions Be Achieved?

If you want to experience UniswapX, you just need to enable the “UniswapX” switch in the settings button in the upper right corner of the Uniswap web application. After conducting a practical test of the product, BlockBeats found that currently only a few currencies such as DAI, UNI, 1INCH, and APE can achieve gas-free transactions through the UniswapX route. However, currencies such as AAVE, ARB, and USDT often cannot use the UniswapX route. This is because when users enable the UniswapX route, the Uniswap web application will automatically filter the best trading path for users based on the optimal transaction fee. That is, when the slippage of V2 or V3 is lower than that of UniswapX, Uniswap will automatically redirect users to the trading paths of the former two.
