Uniswap vote expands UNI burns to BNB, Polygon, Celo

Uniswap governance opened a May 24 vote to extend protocol-fee collection and UNI burning to BNB Chain, Polygon and Celo, according to the project’s governance forum. The proposal is the latest step in Uniswap’s “UNIfication” rollout, a fee-switch framework approved in late 2025 that routes protocol revenue into a burn mechanism for UNI rather than distributing fees directly to token holders. The three-chain expansion would add BNB Chain and Polygon to the system and complete Celo activation after an earlier configuration error, according to the proposal text. If approved, the move would widen a rollout that began on Ethereum mainnet and later spread to multiple other networks. ### What exactly is Uniswap token holders voting on? A May 16 temperature check on Uniswap’s governance forum said the proposal would “extend the infrastructure for collecting and burning protocol fees to BNB Chain and Polygon” and “complete Celo’s fee activation through a corrected cross-chain governance path.” The same post said fees on each chain would be routed to a TokenJar on that network, with UNI then bridged back to Ethereum mainnet and sent to the burn address at 0xdead. (gov.uniswap.org) The governance post said the proposal follows earlier votes numbered #92, #93 and #94 and uses an expedited process created under UNIfication. Under that framework, fee-parameter updates can skip the usual request-for-comment stage and go directly to a five-day Snapshot vote followed by an onchain vote, the forum said. (gov.uniswap.org) ### How does this fit into the broader UNIfication plan? A Nov. 10, 2025 governance post by Hayden Adams, Ken Ng and Devin Walsh said Uniswap Labs and the Uniswap Foundation proposed turning on protocol fees and using those fees to burn UNI as part of a broader governance overhaul. That post said the protocol had processed about $4 trillion in volume and described a phased rollout beginning with v2 pools and a set of v3 pools on Ethereum mainnet before expanding to layer-2 and other chains. (gov.uniswap.org) A Feb. 18, 2026 proposal said protocol fees had already been expanded to Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain and Zora, and that UNI burned on those networks would be bridged back to Ethereum mainnet. The May 16 proposal said the rollout had since reached nine additional chains beyond Ethereum mainnet and that the burn system was “working as designed.” (gov.uniswap.org) ### Why is Celo included again? The May 16 governance post said Celo had already been approved in a previous proposal but “did not execute due to a configuration error.” The new measure would complete that activation through what the proposal called a corrected cross-chain governance path. Crypto Briefing reported on May 22 that the new proposal treats Celo as a fix while adding fresh TokenJar infrastructure for BNB Chain and Polygon. (gov.uniswap.org) That report also said the phased rollout started on Ethereum mainnet in late December 2025. ### What fee settings are being used on the new chains? Crypto Briefing reported that protocol fees on the new chains are set at one-fifth of the pool fee, matching settings already used on other integrated chains. (gov.uniswap.org) In that example, a pool charging a 0.30% swap fee would direct 0.06% to the protocol. The Uniswap forum post did not spell out that ratio in plain-language examples, but said protocol fee levels would be the same as on other chains where fees are already live. (cryptobriefing.com) The Feb. 18 governance post also said Uniswap was moving toward a tier-based v3 fee system in which pools sharing the same liquidity-provider fee tier could have uniform protocol-fee settings, while governance retained the ability to override fees on individual pools. ### What happens next in the process? (cryptobriefing.com) The May 16 post said the proposal would proceed through a five-day Snapshot vote and then an onchain vote if it advanced. Uniswap’s governance portal showed prior protocol-fee expansion proposals as part of the same sequence, including “Protocol Fee Expansion: Vote 2,” which was marked executed on March 7, 2026. (gov.uniswap.org) A successful vote would authorize one action each for Celo, BNB Chain and Polygon, with multiple inner calls for fee collectors, ownership transfers and message-routing contracts, according to the proposal specification on the governance forum.
