SummerHook

EthereumRegistered

Uniswap v4 hook for the Summer protocol that gates pool initialization to the Launchpad, enforces full-range LP positions, and charges a 0.25% protocol fee on each swap's unspecified-currency side via afterSwapReturnsDelta. Also runs a 4-week SUMMER token farming program with vesting for LP stakers and a Founders Pool for Genesis Badge holders.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
