Uniswap Activates v4 Protocol Fee Switch, Directing Fees Toward UNI Buy-and-Burn Mechanics

Uniswap has activated a protocol fee switch on v4 liquidity pools, directing collected fees toward UNI buy-and-burn mechanics. This move comes after Uniswap governance proposal 100 passed with 46.6 million votes in favor and 1.27 million opposed.

The new mechanism collects around one-sixth of swap fees into TokenJar contracts, which are then used to purchase and burn UNI tokens. Daily protocol revenue has reportedly risen to approximately $325,000 from a prior run rate near $114,000.

This shift is significant because it moves Uniswap's fee structure away from direct distributions to token holders and toward a more active value-capture model. The mechanism does not pay UNI holders directly; instead, collected fees are used to buy and burn UNI tokens, reducing supply and potentially supporting token economics.

While this change may impact liquidity providers' yields, the validated notes indicate that LP yields remain unchanged due to the additive nature of the fee switch. Uniswap's new v4 architecture is designed to be more flexible than earlier versions, allowing for varied pool design and execution paths across multiple networks.
