[Uniswap Fee Switch Proposed to Expand to Eight Chains, UNI Burn Allows Claiming Protocol Revenue] According to a report by Jinse Finance, Uniswap token holders began voting on a major proposal this Thursday, aiming to activate the protocol fee switch on two protocol versions across eight Layer 2 blockchains, including Base, Arbitrum, and OP Mainnet. Once activated, at least one-sixth of the fees collected by liquidity providers on these chains will be transferred to the token pool, allowing investors who burn an equivalent amount of UNI tokens to claim the revenue. This is expected to more than double the current revenue. The fee switch has been live on Ethereum mainnet v2 and certain v3 liquidity pools since December last year, generating $3.3 million in revenue to date. Since 2026, Base has surpassed Ethereum to become the largest fee-generating chain for Uniswap, producing $55 million in fees. Boosted by the proposal news, UNI has risen 9% over the past seven days, outperforming Bitcoin and Ethereum, which both declined during the same period. The final vote will conclude on March 4.
