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 registry, not tradeable in Uniswap’s app yetUnregistered hooks get less scrutiny. Most scam hooks are unregistered. It runs code on swaps, so Uniswap’s app only routes it once Uniswap Labs approves it, and it isn’t approved yet. Adding liquidity still works, and other apps can trade it.Registry Routing rules

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