EulerSwap

EthereumRegistered

EulerSwap is a custom-curve AMM hook that handles all swap logic in beforeSwap, depositing input tokens into Euler Finance vaults and withdrawing output tokens, while verifying a proprietary bonding curve invariant. It returns a BeforeSwapDelta to fully bypass standard Uniswap v4 AMM pricing.

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.
