EulerSwap

ArbitrumRegistered

EulerSwap is a Uniswap v4 hook that implements a custom AMM curve backed by Euler Finance lending vaults. It handles the entire swap in `beforeSwap` by computing quotes against its internal curve, taking input tokens into an Euler vault, and paying output tokens from another vault, returning a `BeforeSwapDelta` to bypass standard pool manager accounting.

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.
