EulerSwap

EthereumRegistered

A Uniswap v4 hook that replaces the standard AMM curve with a custom two-asset curve backed by Euler Protocol lending vaults. Swaps are fully intercepted in beforeSwap via BeforeSwapDelta: input tokens are deposited into and output tokens withdrawn from Euler vaults, with configurable fees, protocol fees, and optional temporal expiration.

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.
