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.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Automated checks, not an audit

✓Not upgradeableNo proxy pattern found: the code is fixed.

✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).

!Not in Uniswap’s hook registryUnregistered hooks get less scrutiny. Most scam hooks are unregistered.

✓Source code publishedThe code on the block explorer matches what's deployed (contract: DuckHookV4).

iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
