PhiEthHooks

BaseRegistered

Implements a 1:1 custom swap curve for ETH/phiETH pools by handling actual ETH deposits and phiETH withdrawals inside beforeSwap via BeforeSwapReturnsDelta, bypassing the AMM entirely. Prevents direct liquidity additions to the pool and enforces a zero-fee constraint on pool initialization.

What it can do

Runs on every swap

Its code executes inside each trade in pools that use it.

Can change what you receive

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Controls who can add liquidity

It checks every deposit before it goes in.

Checks new pools

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