Uniswap adds seven trading sources as 0x disputes its protection from malicious hooks

Summary

Uniswap Labs launched aggregator hooks on Ethereum, Base and Robinhood Chain, routing swaps through seven external liquidity sources that it says cover over 90% of DEX activity on those networks. The launch comes amid disputes over whether routers adequately screen malicious Uniswap v4 hooks, which 0x says have quoted favorable prices but delivered worse execution, including reported losses of up to 50%. Uniswap argues aggregators should vet hooks and says its router applies approval rules; 0x alleges a malicious hook was allowlisted and cited a trade that allegedly lost 1.2% overall. Uniswap’s guidance and an OpenZeppelin audit document some routing and slippage safeguards, but their scope and default application across the new integrations remain unclear. Whether the adapters screen underlying pools is also unconfirmed.
