Programmable market engine hook that charges dynamic fees on the quote leg of every swap. Fee rates are tiered by trade size and can evolve over time or cumulative volume via configurable stages. Enforces min/max trade size bounds per market and routes fees to market-defined recipients via a separate vault.

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.
Sets its own swap fee
Pools using it let the hook choose the swap fee instead of a fixed tier.
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.
