Uniswap Labs has introduced a governance proposal to significantly expand its protocol fee collection across the Uniswap ecosystem. The proposal aims to activate protocol fees for all remaining v3 pools on the Ethereum mainnet and extend fee collection to v2 and v3 deployments on eight additional blockchain networks: Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora.
The proposal utilizes the new "UNIfication" governance process, which allows for a streamlined update path. A five-day temperature check vote on Snapshot is currently underway, scheduled to conclude on February 23, 2026. If approved, it will proceed to parallel onchain votes. Due to a 10-action limit in the GovernorBravo contract, the implementation will be split into two proposals: one covering the mainnet fee controller plus Base, OP Mainnet, and Arbitrum, and another covering Celo, Soneium, Worldchain, X Layer, and Zora.
A key technical component is the introduction of a tier-based "v3OpenFeeAdapter." This new adapter would automatically apply a default protocol fee to all v3 pools based on their liquidity provider fee tier (e.g., 0.05%, 0.30%, 1%), moving away from the current model where governance must manually enable fees pool-by-pool. Governance would retain the ability to override fees for specific pools if needed.
The expanded fees will feed directly into Uniswap's established fee-and-burn mechanism. On each supported chain, collected fees will be routed to a chain-specific "TokenJar" contract. For Layer 2 networks, the accumulated value will be bridged back to the Ethereum mainnet. There, along with fees collected directly on Ethereum, the funds will be permissionlessly converted into UNI tokens and sent to a burn address (0xdead), permanently removing them from circulation.
Uniswap Labs stated that the initial, staged rollout of protocol fees since the UNIfication upgrade in late December 2025 has "gone well," with total value locked (TVL) on Ethereum mainnet increasing on a market-adjusted basis. The proposal represents the next phase in broadening the protocol's revenue framework. This move aligns with Uniswap's recent expansion of services, including the launch of Continuous Clearing Auctions on Arbitrum and a partnership with Securitize Markets to enable trading of BlackRock's BUIDL fund on UniswapX.
