Uniswap has submitted two governance proposals aimed at implementing new protocol fees across multiple chains, including Ethereum and Robinhood Chain. Founder Hayden announced that the proposals, now up for final on-chain voting, will enable v2 and v3 protocol fees on Robinhood Chain and v4 fees on Ethereum, Base, Arbitrum, Robinhood, BNB, Polygon, and Optimism. A third proposal for additional v4 chains is forthcoming. The new fees are designed to enhance the UNI burn mechanism, potentially increasing the burn rate significantly due to high trading volumes, particularly from Robinhood-related activities. This move is expected to positively impact the value of UNI by reducing its circulating supply.
