New Uniswap Proposal Targets All V3 Pools and 8 New Networks

• Uniswap plans to activate protocol fees on all v3 pools using a tier-based system for faster governance updates.
• The proposal expands protocol fees to eight networks, routing revenue back to Ethereum for UNI token burning.
• Governance will vote through two parallel proposals due to action limits in the onchain voting system.

Uniswap governance is considering a major protocol fee expansion. A new temp check proposal, authored by Erin Koen, wants to activate fees on all v3 pools on the Ethereum mainnet. It also aims to bring protocol fees to eight additional chains.

The proposal marks the first use of Uniswap’s new streamlined governance process approved under UNIfication. If it passes, the changes could reshape how Uniswap collects and burns UNI across multiple networks.

Uniswap’s Fee Rollout Moves to More Chains

The proposal targets Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. Each chain would receive both v2 and v3 protocol fees. Fees collected on these chains flow into a TokenJar contract on each respective network.

From there, UNI gets bridged back to Ethereum mainnet and sent to a burn address. The same infrastructure already handles Unichain sequencer fee burns, according to the proposal.

Koen notes that the earlier fee rollout on Ethereum mainnet went well. Market-adjusted TVL on mainnet has risen since December. The burn system has also been working as expected, converting fees from many different tokens into UNI burns without requiring manual steps.

A Tier-Based System for All V3 Pools

One of the bigger changes in this proposal is how v3 fees get managed. Today, the v3FeeAdapter handles fees pool by pool. Governance maintains a running list of individual pools and their fee levels. This proposal replaces that setup with a new v3OpenFeeAdapter.

The new adapter sets protocol fees uniformly across all pools that share the same LP fee tier. Any new pool automatically gets the default protocol fee for its tier. No separate governance action is needed for each pool.

For example, all pools with a 1 basis point LP fee could have protocol fees set at 25%. Governance still retains the ability to override fees on specific pools if needed.

The proposal also introduces a faster path for fee updates. Under UNIfication, fee parameter changes skip the RFC stage entirely.

They go straight to a five-day Snapshot vote, followed by an onchain vote. This cuts down the time needed to make adjustments while keeping onchain security intact.

Due to GovernorBravo’s limit of 10 actions per proposal, the onchain vote will split into two parallel proposals. One will cover mainnet changes plus Base, OP Mainnet, and Arbitrum. The other will handle Celo, Soneium, Worldchain, X Layer, and Zora.

The temp check is currently active in the Uniswap governance forum. Community members can weigh in before the proposal moves to a Snapshot vote.
