Uniswap governance is voting on enabling protocol fees for all remaining v3 liquidity pools on Ethereum mainnet and expanding the mechanism to Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. Fees on Layer 2 networks would be collected using the TokenJar contract, then bridged to mainnet for UNI buyback and burn under the post-UNIfication framework. Voting concludes on February 23, marking a further step in broadening Uniswap’s fee capture and deflationary token strategy.
