Uniswap just flipped a switch that DeFi watchers have been anticipating for years. On July 27, 2026, the protocol executed Governance Proposal 100, activating protocol fees across selected v4 liquidity pools on seven networks simultaneously.

The early revenue number tells the story quickly: roughly $325,000 per day flowing into the protocol from day one.

What the fee switch actually does

Specifically, the protocol fee is set at approximately one-sixth of the existing swap fee. On a standard 30 basis point pool, that translates to about 5 basis points going to the protocol. Traders pay a marginally higher effective cost, but liquidity providers keep their yields largely intact.

Uniswap founder Hayden Adams addressed LP earnings directly, making clear the design intent was to avoid cannibalizing the returns that keep liquidity in the pools in the first place.
