Uniswap DAO has unveiled a new proposal to extend its fee collection and UNI token burn mechanism to BNB Chain, Polygon, and Celo, aiming to expand the popular UNIfication program beyond its current scope on Ethereum and other major networks. If approved, this move would integrate three new blockchains into Uniswap’s evolving ecosystem, reinforcing its multi-chain ambitions.
Community vote set for May 2026
The proposal, titled “Protocol Fee Expansion: Vote 3” (Proposal #96), appears on the Uniswap governance portal and is scheduled for a community vote starting May 24, 2026, according to the Uniswap Foundation calendar. Should the community approve, the fee-burning mechanism—already live on Ethereum, Arbitrum, Base, OP Mainnet, and several others—would now launch on these three additional chains.
Details in the proposal specify that, on BNB Chain and Polygon, fees from v2 pools will be channeled directly to a smart contract called TokenJar, while v3 factory management will transfer to the advanced V3OpenFeeAdapter contract. On Celo, implementation will be more complex due to previous technical issues, requiring the use of cross-chain accounts for some operations.
Glossary: TokenJar and Firepit are key smart contracts for Uniswap’s fee accrual and burning process. TokenJar gathers protocol fees on each chain, while Firepit completes the burn by destroying an equivalent amount of UNI tokens.
The system is designed so that accumulated protocol fees are consolidated in a central account. Users must first burn UNI, after which the burnt UNI is sent to the famed “0xdead” address on Ethereum’s mainnet for finalization.
Impact of the fee burn program on Uniswap
UNIfication was introduced on Uniswap in December 2025 via community vote, directly linking fee collection and burning to increased UNI token engagement. During this period, UNI rallied from $4.95 up to $9.25 in a short span, reflecting rising interest after implementation.
Back in March, Proposals 94 and 95 saw support from a combined 139 million UNI, enabling the fee collection mechanism to expand across eight further blockchains.
The latest Proposal 96 would bring the total number of UNIfication-enabled networks to eleven. On the activated chains, v2 pools split the standard 0.3% trading fee, with 0.25% going to liquidity providers and 0.05% allocated for the protocol. For v3 pools, fee parameters are set by the new adapter contract per the proposal.
Uniswap’s financial profile and network data
Data from Defillama shows that Uniswap’s cumulative protocol fees across all blockchains have reached $5.57 billion to date. Annually, the protocol generates approximately $477 million in revenue, with $3.3 billion currently locked in the platform.
BNB Chain has contributed $117 million in total value locked (TVL) and $3.53 million in protocol fees over the last 30 days, while Polygon accounts for $76.5 million TVL and $1.02 million in fees for the same period. However, fee rewards for UNI holders are not yet distributed on these two networks pending proposal approval.
| Network | Total Value Locked (TVL) | 30-Day Fees | Distributed to UNI Holders |
|---|---|---|---|
| BNB Chain | $117 million | $3.53 million | No |
| Polygon | $76.5 million | $1.02 million | No |
| Celo | $4.87 million | $174,000 | No |
Recent price movements captured by CryptoAppsy indicate that UNI is currently trading at $3.30, a steep decline of 92.7% from its all-time high of $44.97 in May 2021.
As part of UNIfication, a total of 100 million UNI sourced from the treasury were retrospectively burned as a lump sum, calculated to represent fees that might have been accrued from the program’s inception. The proposal was co-authored by Uniswap founder Hayden Adams.
Streamlined governance rolls out for faster changes
The latest proposal implements the expedited governance process introduced with UNIfication. Under this fast-tracked system, fee parameters discussed in the community can progress from a five-day Snapshot poll to an on-chain vote immediately, expediting important protocol updates.
