Uniswap readies votes to add v4 and Robinhood Chain fees to UNI burn system

Robinhood Chain and v4 proposals

The Robinhood Chain proposal would activate protocol fees for Uniswap v2 and v3 on that network. According to the proposal materials, Uniswap deployments on Robinhood Chain had surpassed $6 billion in cumulative swap volume by July 10.

A separate proposal would enable protocol fees for selected Uniswap v4 pools on Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and Robinhood Chain. Uniswap governance is expected to consider another v4 proposal later for five additional networks: Celo, Soneium, Worldchain, X Layer and Zora. The split is due to the action limit in Uniswap’s GovernorBravo governance contract.

How the burn mechanism works

If approved, fees collected under both proposals would be routed into Uniswap’s TokenJar system. In that setup, searchers can claim accumulated fee assets by supplying UNI of the same value. The UNI used in those claims is then sent to a burn address. For fees collected on networks other than Ethereum, the UNI is bridged back to Ethereum before being destroyed.

The proposal documents say protocol fees are already active across v2 and v3 pools on 11 networks. They also note that 186,000 UNI was burned in a single day last month. In a post on X announcing the proposals, Hayden Adams said, “Based on current volumes, especially Robinhood, we expect the impact on UNI burn to be substantial.”

Why Robinhood Chain matters

Robinhood Chain has become a notable source of Uniswap activity shortly after its July launch. The network reached $500 million in daily Uniswap volume within eight days, placing it behind only Ethereum mainnet for daily activity at that point, according to the report.

Crypto.news previously reported that Robinhood Chain drew more than $70 million in bridged Ether in its first week and that total value locked rose above $106 million. If the new fee plan is approved, Uniswap governance would be able to capture part of that trading activity through protocol fees and direct it into the UNI burn process.

The Robinhood Chain proposal would use the same cross-chain governance pattern already used for Arbitrum One. Under that model, governance instructions would be sent from Ethereum to Robinhood Chain, where contracts would redirect the relevant protocol fees to TokenJar.

Different fee logic for v4

The v4 proposal requires a different implementation because Uniswap v4 supports hooks and dynamic fee settings. To handle that, the plan introduces a V4FeePolicy contract to calculate protocol fees, along with a V4FeeAdapter that would apply governance rules and collect those proceeds.

The first v4 vote would cover three pool categories: static-fee pools, pools launched through continuous clearing auctions, and aggregator-hook pools. Together with the separate Robinhood Chain proposal, the July governance package would extend Uniswap’s existing fee-switch and burn framework to v4 for the first time, while also adding Robinhood Chain’s v2 and v3 activity if token holders approve the measures.

The proposed changes build on the UNIfication overhaul, which linked protocol fee capture with UNI burns. The upcoming votes do not guarantee activation, but they would broaden the fee sources feeding that system across more chains and newer pool designs if passed.
