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.

✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: V4TaxHook).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
iRestricted swapsSwap access: governance. Not everyone can trade every pool.
