Uniswap Labs proposes activating protocol fees for v4 pools across 11 chains

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.

The UNIfication backstory

Protocol fees on Uniswap were a dormant concept for years. That changed in December 2025 when UNI holders approved the UNIfication package, a sweeping governance proposal that linked protocol revenue directly to UNI token burns. The rollout started with v2 and select v3 pools. Daily UNI burns peaked at 186,000 tokens as fee revenue poured in from the protocol’s most established liquidity venues.

What this means for investors

More pools generating fees means more UNI getting burned. Since the UNIfication launch in December 2025, the burn mechanism has already demonstrated its ability to remove meaningful token supply at scale, with daily burns peaking at 186,000 tokens. Adding v4 pools to the mix expands the revenue surface area significantly, particularly as v4 adoption grows.

The configurable fee curve system allows governance to optimize fee rates over time rather than applying a fixed fee regardless of market conditions. If a particular pool type is seeing massive volume, fees can be calibrated to capture more value without driving liquidity providers to competitors.

One risk to monitor is the impact on liquidity providers. Protocol fees are effectively taken from the spread that LPs earn, which means LPs on fee-enabled v4 pools will see slightly reduced returns compared to a zero-fee scenario.

The binding on-chain vote expected the week of July 13 will be the final hurdle. Given the overwhelming Snapshot support, passage would formally activate fee collection on v4 pools and expand the UNI burn engine to its widest scope yet.
