Uniswap adds seven trading sources amid 0x dispute over malicious hooks

Uniswap Labs launched aggregator hooks on Ethereum, Base, and Robinhood Chain on Oct. 22, enabling swaps through external liquidity from Curve, Fluid, and PancakeSwap. However, a September study by trading aggregator 0x found that malicious Uniswap v4 hooks quoted one price but settled at another, with some trades resulting in up to 50% less than quoted. 0x's research examined 84,163 hooks across six chains, classifying 54.2% as malicious. Uniswap founder Hayden Adams rejected the criticism, stating it was a "skill issue," while Paradigm's Dan Robinson argued routers should vet arbitrary hooks before treating them as liquidity.
