PhiEthHooks

BaseRegistered

Implements a 1:1 ETH/phiETH exchange as a custom curve hook, bypassing Uniswap v4's AMM entirely by taking input tokens from the pool manager, wrapping/unwrapping via the phiEth contract, and settling the output directly. Liquidity addition is blocked; only zero-fee ETH/phiETH pools may use this hook.

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.
