Uniswap governance has started to move. The expansion of the fee switch is about to spread across the entire layer 2 network.

Until now, Uniswap has operated on a model that allocates 100% of trading fees to liquidity providers. However, that structure changed with last year's "UNIfication" initiative. This proposal is a significant step toward expanding that approach into layer 2.

Plans are underway to enable protocol fees on eight layer 2 networks: Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. The additional annual revenue on these chains is estimated at around $27 million. When combined with existing fees on the Ethereum mainnet, this could lead to approximately $34 million in annual UNI token burns, bringing total annual revenue close to $60 million.

There are also technical innovations to watch. The new "LayerBase Adapter" eliminates the need for repeated voting for each trading pair on layer 2. Based on existing fee tiers (0.01%, 0.05%, 0.30%, etc.), protocol fees will be automatically applied. When new tokens are launched, the protocol can immediately earn revenue without governance delays.

However, there are trade-offs. Since protocol fees are deducted from traders' total fees, technically, LP returns will decrease. While DEXs like Aerodrome and Camelot are offering high incentives on layer 2, Uniswap must balance maintaining liquidity with securing protocol revenue.

Supporters argue that Uniswap’s brand strength and close ties with aggregators will create a "moat" that allows it to maintain an advantage even with minimal protocol fees.

Interestingly, this model suggests a broader implication for DeFi. It signals a shift from "valueless governance tokens" to tokens supported by transparent, on-chain cash flows. If successful in the complex multi-chain environment of layer 2, it could set a precedent for how decentralized protocols manage intricate financial systems.

Voting was scheduled to take place from late February to early March. This decision will serve as an indicator of market perception regarding the balance between protocol profitability and ecosystem growth. The strategic shift of Uniswap into the layer 2 era is worth paying close attention to.
