EulerSwap

UnichainRegistered

EulerSwap is a custom-curve AMM hook backed by Euler Finance vaults that handles swap execution entirely in beforeSwap: it deposits input tokens into an Euler vault and withdraws output tokens from another Euler vault, enforcing a custom price curve invariant. It intentionally reverts on liquidity additions, donations, and external pool initialization to prevent misuse of the hook address.

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.
