Uniswap Founder Rejects Claims That New v4 Fees Cut Into LP Earnings

“FUD and misunderstanding.” That’s how Uniswap founder Hayden Adams described the backlash over newly activated protocol fees — a dispute that boils down to a disagreement over basic math.

The Vote That Started It

Governance proposals to activate protocol fees across Uniswap’s v4 pools went to an onchain vote that ran through July 26, covering static-fee pools, pools launched through continuous clearing auctions, and aggregator-hook pools. The fees would apply across seven networks: Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain.

The Criticism

Once the fees activated, critics argued the change effectively cut into how much liquidity providers earn from supplying capital to Uniswap’s pools, with some characterizing the new protocol fee as taking a meaningful slice, around 25%, directly out of LP profits.

Adams’ Response

Adams pushed back directly, calling the criticism a misunderstanding of how the fee actually works. Using a 30-basis-point pool as his example, he argued that a 5-basis-point protocol fee represents roughly 14% of total swap fees generated, not a cut taken from LPs’ existing earnings. His core point: the protocol fee is additive, layered on top of the swap fee structure, rather than deducted from what liquidity providers were already earning.

Why This Argument Matters Beyond Uniswap

How protocol fees are structured, and how clearly that structure is communicated, directly affects whether liquidity providers keep supplying capital to a decentralized exchange, since LP participation is what makes trading on these platforms possible in the first place. A dispute over whether a fee is “additive” or “deducted” sounds technical, but it determines whether LPs believe they’re being paid fairly, which in turn affects how much liquidity stays on the platform.

As more decentralized exchanges experiment with their own protocol-level fees to fund development and token buybacks, this exact disagreement, over how a fee change is framed and understood by the people actually providing the liquidity, is likely to resurface elsewhere in DeFi.
