Uniswap V4 is the fourth iteration of the Uniswap AMM protocol. It uses the CLMM logic from Uniswap V3 and creates novel features to be created on top of it through Hooks . Hooks allow flexible AMMs strategies and protocols to be created on top of Uniswap infrastructure, diminishing the effort and cost that it takes to create and innovate on AMM strategies and protocols.

The actors interacting with this protocol could be labeled as LPs, Swappers, Donators and Hooks. These roles are not mutually exclusive and the same actor could perform all of these actions.
