Fee-skimming hook for the STACK/ETH pool. Charges 2% on buys and 3% on sells, taking the fee in ETH and forwarding it to the STACK token contract for holder distribution. Caps individual buy amounts at 1% of total supply for the first 20 swaps as an anti-snipe measure. Ownerless with no admin controls.

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.
Runs at pool creation
It runs when a pool is created, often to lock in that pool’s settings.
