EulerSwap

UnichainRegistered

A custom curve AMM hook that integrates Uniswap v4 with Euler Finance vaults. In beforeSwap, it computes swap amounts using a proprietary bonding curve, takes input tokens from the PoolManager and deposits them into an Euler vault, then withdraws output tokens from a paired Euler vault and settles via BeforeSwapDelta. Direct liquidity additions 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.
