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.

It takes an average of 4.8 years from finalizing investment to starting construction of a data center project, and an additional 2.6 years from construction start to becoming operational. Servers usually cannot be installed until after the building structure and racks are completed. For trade partners such as Taiwan (China), South Korea, and Mexico who rely on US data center supply chain demand, the inertia in construction timelines provides at least a one- to two-year buffer for future exports.
Federal Reserve Major Debate: When Should the Tenure of “Number Three” Williams End?
The main point of contention is whether Williams should step down in June 2028, upon completing a full 10-year term, or in June 2027, when he reaches the mandatory retirement age of 65. Analysts point out that the Federal Reserve Board holds ultimate discretion; if he leaves early, Fed Chair Waller would be able to assert greater control over the appointment to this critical position. However, forcing Williams to shorten his term could easily be interpreted as political manipulation. Williams himself is expected to serve until June 2028.
