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.

Takes a cut when LPs withdraw

It can change what LPs get back when they remove liquidity.

Automated checks, not an audit

!Has an adminowner() is 0xc5b0…3485. That account can usually change fees, limits or allowlists after you trade.

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

!Source code not publishedNobody can read what this hook actually does. Treat it as a black box.
