EulerSwap

UnichainRegistered

A Uniswap v4 hook implementing a custom bonding curve backed by Euler vault assets. Swaps are handled entirely in beforeSwap: it computes output via a custom curve (CurveLib), deposits input tokens into and withdraws output tokens from Euler vaults, and returns the full BeforeSwapDelta, bypassing standard AMM pricing. Add-liquidity and donate are blocked to prevent unproductive positions.

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.
