PhiEthHooks

BaseRegistered

A custom-curve hook enabling 1:1 swaps between ETH and phiEth (an ETH wrapper token). It uses beforeSwapReturnsDelta to take input tokens, deposit or withdraw via the phiEth contract, and settle outputs directly, bypassing concentrated liquidity. Direct liquidity additions to the pool are permanently blocked.

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.
