Uniswap Expands Fee Switch to 8 Chains
Uniswap's protocol "fee switch" is set to expand to eight different chains. The mechanism will allow users who burn UNI tokens to earn a share of protocol revenue, potentially reigniting interest in UNI as a productive, revenue-generating asset across the multi-chain EVM landscape.
This expansion of the fee switch to eight new chains—Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora—is the second phase of a broader strategy that began in late 2025 with the "UNIfication" proposal. That initial move activated protocol fees on the Ethereum mainnet and was a fundamental shift in Uniswap's tokenomics, moving UNI from a pure governance token to one with a direct claim on protocol revenue. The latest proposal is projected to add an extra $27 million in annualized revenue. This is on top of the roughly $34 million already being generated annually from the fees on Ethereum. If the expansion passes, the total annualized revenue directed to UNI token holders could approach $60 million. A key technical upgrade in this proposal is the introduction of the "v3OpenFeeAdapter." This automates fee collection across all Uniswap v3 pools based on their existing fee tiers, eliminating the need for individual governance votes for each new trading pair. This ensures that as new tokens launch on these Layer-2 networks, the protocol can immediately capture a share of the trading volume. The collected fees from these eight chains will be bridged back to the Ethereum mainnet. There, they will be used to buy back and burn UNI tokens, creating a deflationary pressure on the token's supply. This mechanism directly links the trading activity across the entire Uniswap ecosystem to the value of the UNI token. This move is being closely watched as a bellwether for the broader DeFi sector, signaling a larger trend away from "worthless governance tokens" towards tokens backed by transparent, on-chain cash flows. The successful scaling of this model across multiple chains sets a precedent for how decentralized protocols can manage complex, multi-chain financial systems. Since the initial fee switch was activated in late 2025, over $5.5 million worth of UNI has already been burned. The on-chain governance vote for this expansion is scheduled between late February and early March 2026. The proposal has already seen a positive reaction in the market, with the price of UNI jumping 15% in a single day following the announcement, outperforming both Bitcoin and Ethereum.
