Uniswap Labs kicked off a temperature check on July 7 to turn on protocol fees for select Uniswap v4 pools, pushing the exchange’s fee switch into its most advanced and flexible pool architecture. Early Snapshot results show the proposal cruising toward approval with over 93% of votes in favor, roughly 13.9 million UNI voting yes against about 1 million voting no.
If the five-day Snapshot vote, which runs through July 12, passes, binding on-chain votes are expected the week of July 13. The proposal would extend fee collection to v4 pools across 11 different blockchain networks, including Ethereum, Arbitrum, and Polygon.
What the v4 fee switch actually covers
The fee proposal doesn’t apply a blanket charge across every v4 pool. It targets three specific pool families: static fee pools, Continuous Clearing Auction (CCA) pools, which use auction-based mechanisms to capture value from order flow, and aggregator hook pools, which route liquidity through aggregation layers.
The technical implementation runs through a replaceable contract system. Two key contracts, the V4FeePolicy and V4FeeAdapter, handle the actual fee logic. This setup allows for configurable fee curves, meaning governance can adjust fee parameters over time without deploying entirely new infrastructure. Fees collected flow into what are called TokenJars deployed across the various chains, with the resulting UNI burns bridged back to Ethereum mainnet.
