Custom-curve hook implementing 1:1 ETH↔phiEth swaps by intercepting beforeSwap to take input from the PoolManager, deposit/withdraw via the phiEth contract, and settle output — fully bypassing the AMM. Liquidity cannot be added directly to the pool; only ETH/phiEth pools with zero fee are permitted.

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.
