EulerSwap

UnichainRegistered

A custom AMM hook that fully manages swap execution through Euler Finance lending vaults, bypassing Uniswap's internal pool math. In beforeSwap, it takes input tokens and deposits them into an Euler vault, withdraws output tokens from another vault, returns a BeforeSwapDelta, and enforces a custom bonding curve invariant on reserves. Standard liquidity provision and donations are blocked.

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.
