PANews reported on May 25 that according to official news, the Uniswap Foundation announced that it will launch an on-chain vote for the upgraded protocol next Friday (May 31) to reward UNI token holders who have staked and delegated their tokens. UNI holders who wish to vote on the proposal must delegate UNI to themselves or a third party before the voting begins. Users who hold UNI but do not authorize in time will not be able to vote.
