TransparentHook

EthereumRegistered

A Uniswap v4 hook that implements phased buy and sell fees (higher opening rates, then baseline rates), routing buy-fee tokens into a seller inventory that is automatically sold via nested swaps into the pool before each user sell, with ETH proceeds forwarded to a collector address.

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.
