UNI burn poised to grow as Uniswap governance votes on v4 fees and Robinhood Chain expansion

Uniswap (UNI) governance is set to vote on activating protocol fees for selected Uniswap v4 pools for the first time, alongside a separate measure that would extend v2 and v3 fee collection to Robinhood Chain.

Both proposals have been submitted for final onchain votes, which open Sunday and run through July 26. Citing current trading volumes, especially on Robinhood Chain, Uniswap founder Hayden Adams wrote on X Friday that "we expect the impact on UNI burn to be substantial."

The v4 proposal would activate fees for three categories of pools: static-fee pools, pools launched through continuous clearing auctions, and aggregator-hook pools, across Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and Robinhood Chain. A second proposal covering the remaining five chains will follow because Uniswap’s GovernorBravo contract limits proposals to 10 onchain actions, according to the proposal text.

The separate Robinhood Chain proposal, submitted by Adams, would enable v2 and v3 fees on the network, where Uniswap deployed all three protocol versions at the chain's July 1 mainnet launch. Those deployments passed $6 billion in cumulative swap volume as of July 10, per the proposal.

Robinhood Chain, an Ethereum Layer 2 built with Arbitrum's tech stack, pulled about $3.1 billion in DEX volume during its first week, with early trading dominated by memecoins, The Block previously reported.

Fees collected under both proposals would feed the burn mechanism established by UNIfication, the governance overhaul that passed in December with 99.9% support. That vote turned on protocol fees for v2 and v3 pools on Ethereum mainnet and burned 100 million UNI from the treasury, but deferred v4 fees to a later proposal.

The rollout has since reached 11 chains, and the protocol burned a record 186,000 UNI in a single day last month, according to the v4 proposal.

Activating fees on v4 required new infrastructure. Unlike v2 and v3, which use fixed fee tiers, v4's hook architecture lets pools charge fees that can change from one block to the next. The proposal introduces a governance-controlled system that sorts pools into "families" and computes each pool's fee from a set of rules rather than pool by pool.

Both measures use the expedited governance path approved under UNIfication, which skips the request-for-comment stage in favor of a five-day Snapshot vote followed by an onchain decision. Uniswap governance began weighing the broader fee expansion in February.

UNI is currently trading around $3.50, about flat over the past 24 hours, according to The Block's Uniswap Price page.
