Wu said that Uniswap Labs officially announced that UniswapX has just undergone a major upgrade, deploying a new auction contract and redesigning the process of order quotation information. The upgrade is said to include faster quotation experience and transaction execution and more MEV returned to exchangers. Currently, the upgrade is online on the Uniswap web app and will soon be available on the mobile app. It is worth reminding that if the UniswapX filler offers a better price, the exchange will be executed through UniswapX; if Uniswap v2 or v3 offers a better price, the exchange will be executed through AMM.
