Uniswap governance is voting on two proposals to activate protocol fees for Uniswap v4 pools and extend v2 and v3 fee collection to Robinhood Chain. Both proposals opened for onchain votes Sunday and run through July 26. Uniswap founder Hayden Adams wrote on X Friday that the impact on UNI burn is expected to be substantial, citing current trading volumes on Robinhood Chain. The votes follow the December UNIfication governance overhaul, which passed with 99.9% support and established the burn mechanism now being extended to additional chains and protocol versions.
Uniswap v4 Proposal Activates Fees for Three Pool Categories Across Seven Chains
The v4 proposal would activate fees for three categories of pools: static-fee pools, pools launched through continuous clearing auctions, and aggregator-hook pools. The proposal covers 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 rollout has 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.
Robinhood Chain Proposal Enables v2 and v3 Fee Collection
The separate Robinhood Chain proposal, submitted by Adams, would enable v2 and v3 fees on the network. 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.
Fee Revenue Feeds Burn Mechanism Established in December UNIfication Vote
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. 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.
FAQ
What are the two Uniswap governance proposals being voted on through July 26?
The first proposal activates protocol fees for Uniswap v4 pools across three categories (static-fee pools, continuous clearing auction pools, and aggregator-hook pools) on seven chains: Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and Robinhood Chain. The second proposal enables v2 and v3 fee collection on Robinhood Chain, where Uniswap deployed all three protocol versions at the chain's July 1 mainnet launch.
How much trading volume has Robinhood Chain generated for Uniswap?
Robinhood Chain deployments passed $6 billion in cumulative swap volume as of July 10, according to the proposal. The chain pulled about $3.1 billion in DEX volume during its first week, with early trading dominated by memecoins.
What is the UNI burn mechanism and how do these proposals affect it?
The burn mechanism was established by the UNIfication governance overhaul, which 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. Fees collected under the two current proposals would feed this burn mechanism. The protocol burned a record 186,000 UNI in a single day last month.
