UniHooks

EulerSwap

UnichainRegistered

A Uniswap v4 hook implementing a custom AMM backed by Euler Finance lending vaults. In beforeSwap, it takes input tokens into an Euler vault and withdraws output tokens from another vault, pricing swaps via a custom dual-curve invariant (concentration-weighted). Standard v4 liquidity positions are blocked; the hook acts as the sole liquidity source.

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.

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.
