# Activate v4 Protocol Fees (Part 1/2)
AI summary
This proposal is the first part of a two-part plan to activate protocol fees on Uniswap v4 pools across several blockchain networks. It builds on previous proposals that enabled fees on Uniswap v2 and v3. The proposal introduces a new 'V4 Fee Controller' system, consisting of a V4FeePolicy and V4FeeAdapter, to manage the collection of fees from v4 pools, which have a more complex and dynamic fee structure due to their 'hook' architecture. This specific vote will activate fees on v4 pools on Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain.
If passed, Uniswap will begin collecting protocol fees from v4 pools on the specified blockchains, potentially increasing revenue for the protocol and UNI token holders. The new fee system is designed to handle the unique characteristics of v4 pools, ensuring a consistent approach to fee collection. The exact financial impact cannot be determined from this proposal alone, as it depends on the volume and fee settings of v4 pools.
