EulerSwap

EthereumRegistered

A Uniswap v4 hook implementing a custom AMM curve backed by Euler Finance lending vaults. Swaps are fully handled in beforeSwap by taking input tokens into Euler vaults and withdrawing output tokens from vaults, with configurable fees and optional expiration-based deactivation of the pool.

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.
