Uniswap v4 fee switch vote wins 93% support ahead of July 12 deadline

Uniswap Labs has launched a July 7 temperature check to activate protocol fees for selected Uniswap v4 pools, moving the fee switch into the protocol’s newest and more flexible pool design. Early Snapshot voting showed more than 93% support, with roughly 13.9 million UNI voting yes and about 1 million voting no. The five-day vote runs through July 12, and if it passes, binding on-chain votes are expected the week of July 13. The proposal would enable fee collection for v4 pools on 11 blockchain networks, including Ethereum, Arbitrum and Polygon, but it does not impose fees across all pools. It applies to three categories: static fee pools, Continuous Clearing Auction (CCA) pools (auction-based order-flow capture), and aggregator hook pools (liquidity-routing add-ons). The system would use two replaceable contracts, V4FeePolicy and V4FeeAdapter, to manage fee logic. That structure allows governance to adjust configurable fee curves over time without rebuilding the underlying infrastructure. Fees would flow into TokenJars on different chains, while resulting UNI burns would be bridged back to Ethereum mainnet. The move builds on the December 2025 UNIfication package, which UNI holders approved to tie protocol revenue to UNI token burns. That rollout began with v2 and select v3 pools, and daily UNI burns peaked at 186,000 tokens. Expanding fees to v4 pools would widen the protocol’s revenue base as adoption grows, though it could also trim liquidity providers’ returns because protocol fees reduce the spread LPs earn. The on-chain vote expected the week of July 13 is the final step before activation.
