Uniswap v4 launches Aggregator Hooks to capture external liquidity fees, edging toward Jupiter's model

Uniswap v4 has launched Aggregator Hooks, wrapping external liquidity sources such as Curve and PancakeSwap into standard v4 pools across Ethereum, Base and Robinhood Chain. The feature automatically routes users to the optimal path between native and wrapped pools without manual approval. While Uniswap claims coverage of over 90% of on-chain DEX activity, data from the launch week shows only 88,101 transactions totaling $2.85 billion, with 85% originating from Sky's LitePSM and generating just $2,059 in fees for Uniswap. The protocol's ability to enhance UNI value capture depends on whether it can activate fee mechanisms on high-volume external pools.
