What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Sets its own swap fee

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

Runs at pool creation

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

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: ImpactHook).
