Uniswap founder Hayden Adams has proposed activating protocol fees on Uniswap v4 across multiple blockchain networks, a move that would substantially increase UNI token burns under the UNIfication system adopted in December 2025. The proposal is currently in a governance temperature check phase, with voting open from July 19 through July 26.
The fee switch would route a portion of trading fees generated on Uniswap v4 pools into the UNI burn mechanism. If approved, it would cover deployments on Ethereum, Arbitrum, Optimism, Polygon, Base, BNB Chain, and other networks where v4 is live. The proposal follows a similar temp check in July that explored turning on protocol fees for v4 pools.
Data from The Block shows that the UNI burn rate has already increased 3x in the past week as Robinhood Chain traction exploded, with the burn mechanism absorbing fees from Uniswap v2 and v3 across seven chains. Hayden Adams noted that activating v4 fees would further accelerate this deflationary pressure on UNI supply.
The proposal represents a significant step in Uniswaps evolution from a purely decentralized exchange into a revenue-generating protocol. Critics have warned that turning on fees risks reducing liquidity provider returns and driving volume to competing platforms. As reported by NewsBTC and AMBCrypto, the governance vote will test whether the UNI community prioritizes tokenholder value over liquidity growth.
