Uniswap announced a new protocol called UniswapX on EthCC 2023, which aimed to provide the best quotes for on-chain swaps by aggregating liquidity from various DEXs. The protocol outsources routing and batching to a permissionless set of fillers, and uses Permit2 executable off-chain signatures, allowing gasless trading, MEV protection, cross-chain trading, and more.

UniswapX quickly drew loads of attention from the crypto community, as well as criticism. Someone thought that the aggregator mechanism of UniswapX was nothing new, and its fillers had the same function as Cow Swap's solver model.
When Dan Robinson, Head of Research at Paradigm and contributor of Uniswap, shared the five reasons he thought "UniswapX changes the game for decentralized exchange, MEV, and interoperability" on Twitter, Curve Finance commented, "Dan, with all respect. The game was changed long ago by 1inch when they first did high-quality aggregation and Cow Swap when they pioneered the solver model. It's good stuff, but you are not really the first or the second."
Interestingly, the two projects Curve mentioned, 1inch and Cow Swap, both mocked UniswapX by memes. Cow Swap said, "thank you Uniswap for validating even more our trading design! Welcome to the party."
And Sergej Kunz, co-founder of 1inch, used the classic Mr. Bean meme.
