EulerSwap

UnichainRegistered

EulerSwap implements a custom AMM curve as a Uniswap v4 hook backed by Euler Finance vaults. Swaps are handled entirely in beforeSwap via a BeforeSwapDelta — depositing input tokens into and withdrawing output tokens from Euler vaults — while verifying a custom bonding curve invariant. Standard concentrated liquidity (addLiquidity, donate) is intentionally 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.

Handles donations to LPs

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