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.

Safety report

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 registryNot listed in Uniswap’s public hook list. Unregistered hooks get less scrutiny, and most scam hooks are unregistered.

!Source code not publishedNobody can read what this hook actually does; only the raw bytecode is public. Treat it as a black box.

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

?No audit linkedAutomated checks only.
