EulerSwap

EthereumRegistered

A Uniswap v4 hook implementing a custom AMM curve backed by Euler Finance lending vaults. In beforeSwap, it computes quotes from a proprietary bonding curve, deposits input tokens into Euler vaults, and withdraws output tokens from vaults, returning a BeforeSwapDelta to handle pool settlement. Native liquidity positions and donations are blocked via revert.

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.
