SeedifyFeeHook

BaseRegistered

A time-based fundraise fee hook for Uniswap v4 that charges configurable fees on swaps involving a designated fundraise token, with a higher initial rate during a launch window that drops to a lower rate afterward. Fees are split between platform and creator treasuries and accumulated for on-demand withdrawal.

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.

Runs at pool creation

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