Uniswap vote could raise UNI burn with v4, Robinhood fees

Uniswap governance will vote from Sunday through July 26 to activate protocol fees for selected Uniswap v4 pools and to enable v2 and v3 fee collection on Robinhood Chain. Fees collected under both measures would be routed to the UNI burn mechanism created by the UNIfication governance package.

The v4 proposal would turn on fees for three pool categories: static-fee pools, pools launched via continuous clearing auctions, and aggregator-hook pools. The change would apply across Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and Robinhood Chain. A separate follow-up proposal will cover the remaining five chains because Uniswap’s GovernorBravo contract limits any single proposal to 10 onchain actions.

The Robinhood Chain measure would permit v2 and v3 pools on that network to collect protocol fees. Uniswap deployed v2, v3 and v4 on Robinhood Chain at the chain’s July 1 mainnet launch. The proposal records roughly $6 billion in cumulative swap volume on Robinhood Chain as of July 10 and about $3.1 billion in DEX volume during the chain’s first week, with early trading concentrated in memecoins. In a post on X, Uniswap founder Hayden Adams wrote that ‘we expect the impact on UNI burn to be substantial.'

UNIfication passed in December with near-unanimous support and included a one-time 100 million UNI burn from the treasury. The package also set an expedited governance route for measures of this type: a five-day offchain Snapshot vote followed by an onchain decision window. Both current proposals are using that fast track.

Activating fees on v4 required new infrastructure because v4 uses a hook architecture that allows pools to change fees from block to block, unlike v2 and v3 which use fixed fee tiers. The v4 proposal would create a governance-controlled system that groups pools into “families” and computes each pool’s fee from a shared set of rules rather than setting fees pool by pool.

Uniswap’s cross-chain deployment now spans 11 networks. Proposal documents say the protocol recorded a single-day burn high of 186,000 UNI last month. Turning on v4 fees would be the first activation of protocol fees for v4 pools; enabling v2 and v3 fees on Robinhood Chain would extend existing fee mechanics to a new Layer 2 built on the Arbitrum technology stack.

The vote follows the UNIfication fast track: a five-day Snapshot vote will determine whether the measures proceed to the onchain execution vote that closes July 26. If approved, fee collection would begin across the designated pools and chains under governance-defined fee families and would be routed to the UNI burn mechanism.

UNI has traded near $3.50 in recent sessions.
