Uniswap governance has moved to extend its UNIfication fee and burn system to BNB Chain, Polygon, and Celo through a new expedited proposal.
Proposal 96, named Protocol Fee Expansion Vote 3, would activate protocol fee collection on the three networks and direct those fees into UNI token burns.
The vote opens on May 24, 2026, as the DAO seeks to widen a mechanism active beyond the Ethereum mainnet.
Proposal Expands UNIFication Beyond Ethereum
The latest proposal follows the rollout of UNIfication, a governance overhaul approved in late 2025. That framework introduced protocol fee collection and a burn process designed to reduce UNI supply when fees are withdrawn from designated contracts.
If approved, the expansion would bring BNB Chain, Polygon, and Celo into the same system used on Ethereum, Arbitrum, Base, OP Mainnet, and several other supported networks. The move would raise the number of chains covered by the program to 11 outside the Ethereum mainnet.
The vote is using the expedited governance route created under UNification. This process allows fee parameter updates to skip the RFC stage and proceed to a five-day Snapshot vote before an on-chain vote.
Fee Contracts Drive The Burn Process
Under the system, protocol fees flow into a contract called TokenJar. Searchers that withdraw those fees must burn an equivalent value of UNI through Firepit, then bridge the burned tokens back to Ethereum and send them to the 0xdead address.
For BNB Chain and Polygon, the proposal would set the v2 factory fee recipient to the TokenJar. It would also transfer v3 factory ownership to a V3OpenFeeAdapter contract.
Celo requires extra steps because an earlier proposal failed due to a configuration issue. The new proposal would transfer the v2 feeToSetter role from Wormhole to a DUNI-owned CrossChainAccount and move v4 PoolManager ownership to the same account.
Wormhole’s Native Token Transfer system would handle cross-chain messaging for BNB Chain and Polygon, while Celo would follow the OP stack architecture used by other layer 2 networks.
Uniswap Fees Highlight Wider Market Impact
Uniswap’s fee expansion has drawn attention because the earlier rollout coincided with a sharp UNI rebound in late 2025. The token remains well below its May 2021 record, trading near $3.30 and down more than 92% from its all-time high.
Defillama data shows Uniswap has generated $5.57 billion in cumulative fees, with annualized fees near $477 million. The protocol also holds about $3.3 billion in total value locked across more than 40 chains.
BNB Chain holds $117 million in Uniswap TVL and generated $3.53 million in fees over 30 days. Polygon holds $76.5 million in TVL and produced $1.02 million in 30-day fees. Neither network sends protocol revenue to UNI burns.
