UniHooks

flETHHooks

EthereumRegistered

A constant-sum 1:1 custom-curve hook for ETH/flETH pools. In beforeSwap, it takes the full input amount, converts it via flETH deposit or withdraw (1:1), and settles the output back to the PoolManager — completely bypassing concentrated liquidity. Direct liquidity addition is blocked; only the ETH/flETH pair with zero fee is accepted.

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.
