PANews reported on December 28th that Uniswap announced on its X platform that it has set all interface fees for its applications and APIs to zero. Uniswap's previous proposal to activate the fee switch has passed its final governance vote. After a two-day lock-up period, the Uniswap v2 and v3 fee switches will be activated on the Unichain mainnet, triggering the burning of UNI tokens.
