EulerSwap

UnichainRegistered

A custom-curve Uniswap v4 hook backed by Euler Protocol vaults. Each pool instance is a minimal proxy using a configurable pricing curve (with concentration and equilibrium reserve parameters). It handles swaps entirely in beforeSwap via a return delta, routing token flows through Euler vaults rather than native Uniswap v4 liquidity, and intentionally blocks native liquidity additions and donations.

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.
