EulerSwap

UnichainRegistered

A custom AMM hook for Uniswap v4 that fully replaces swap execution with its own curve logic backed by Euler Finance lending vaults. In beforeSwap, the hook takes input tokens, deposits them into an Euler vault, withdraws output tokens from the corresponding vault, and enforces a custom curve invariant, returning a BeforeSwapDelta to handle all pool accounting.

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.
