Uniswap is about to flip the fee switch on its newest protocol version, and the community seems pretty enthusiastic about it. On-chain voting for two proposals that would activate protocol fees on select v4 pools across 11 chains is set to begin around July 19, 2026, following a temperature check where 93% of voters backed the move.

That temperature check, which ran from July 7-12, saw 13.9 million UNI vote in favor versus just 1 million against.

What the fee activation actually looks like

The proposal targets three specific categories of v4 pools: static fee pools without hooks, continuous clearing auction pools, and aggregator hook pools. If you’re wondering what hooks are, think of them as customizable plug-ins that let developers tweak how liquidity pools behave. Uniswap v4, which launched on January 31, 2025, introduced this modular architecture as its signature feature.

The fee structures aren’t uniform across all pools. On Base, stablecoin pools would carry a 10 basis point fee. Certain aggregator hooks would get a 25x multiplier applied. The collected fees won’t just sit around on whatever chain they’re generated on. They’ll funnel into what Uniswap calls TokenJars on their respective chains before being bridged back to Ethereum.
