flETHHooks

UnichainRegistered

A custom-curve hook for ETH/flETH pools implementing a 1:1 constant-sum swap: it takes the full input from the PoolManager, converts it via flETH deposit/withdraw, and settles the output back — bypassing concentrated liquidity math entirely. Direct liquidity addition is 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.
