EulerSwap

ArbitrumRegistered

EulerSwap is a custom-curve AMM hook backed by Euler Finance lending vaults. In beforeSwap it computes pricing via its own curve invariant, deposits swap input into an Euler vault, withdraws swap output from another Euler vault, and returns a BeforeSwapDelta to the PoolManager, bypassing Uniswap concentrated liquidity entirely.

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.
