EulerSwap

UnichainRegistered

A custom AMM hook for Uniswap v4 that implements a concentrated liquidity curve backed by Euler Finance vaults. Swaps are handled entirely in `beforeSwap` via `beforeSwapReturnsDelta`, depositing input assets into and withdrawing output assets from Euler vaults while verifying a custom curve invariant. Standard Uniswap v4 liquidity positions and donations are blocked; the hook serves as the sole liquidity source.

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.

Handles LP donations

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