Custom-curve AMM hook for Uniswap v4 that processes swaps entirely in beforeSwap: takes input tokens into an Euler Finance vault, withdraws output tokens from another vault, and verifies the trade against a configurable price curve invariant. All liquidity is provided via Euler margin positions rather than standard Uniswap v4 concentrated liquidity.

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.
