Uniswap governance has launched a crucial temperature check proposal to activate protocol fees across all remaining Uniswap v3 pools on the Ethereum mainnet and expand fee collection to eight additional blockchain networks.
The proposal, which went live on February 18, 2026, aims to transition the decentralised exchange (DEX) from a selective fee model to a comprehensive value-capture system that supports the programmatic burning of $UNI (Uniswap) tokens.
Since UNIfication, we’ve monitored the first wave of fees on v2 and a large subset of v3 pools on mainnet
Rollout went very well, with market adjusted TVL up and burn working efficiently
Now, we propose enabling fees on remaining v3 pools + eight more chains
More 🔥 to come

The current vote, set to conclude on February 23, introduces a tier-based fee adapter designed to automatically apply protocol fees to every v3 pool based on its specific liquidity provider (LP) fee tier. This shift effectively removes the need for governance to manually approve fees for individual pools, streamlining the protocol’s ability to generate revenue.
Expansion to eight additional networks: A multi-chain strategy
Beyond the Ethereum mainnet, the proposal seeks to activate protocol fees on both v2 and v3 deployments across eight prominent chains: Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. Under this framework, fees collected on Layer 2 networks will be stored in chain-specific “TokenJar” contracts before being bridged back to Ethereum to be permanently removed from circulation via the “Firepit” burn contract.
The decision to activate fees is a major change for Uniswap. For years, the $UNI token didn’t offer direct financial rewards from the protocol’s high trading volume. Now, turning on the fee switch directly connects how much the protocol is used to the token’s value by reducing the total supply over time (deflation).
Uniswap has secured a major win for the decentralized finance (DeFi) sector, defeating organizations linked to Bancor in a high-profile patent dispute over automated market maker (AMM) technology.
The legal victory, concerning the core formula that enables automated token swaps on the exchange, was announced by Uniswap founder Hayden Adams on X on February 11. A federal court ruled in Uniswap’s favour, addressing the key question of whether the underlying AMM formula could be legally protected by a patent, as previously reported by DeFi Planet.
