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.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Takes a cut when LPs withdraw

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

Gates who can add liquidity

It checks every deposit before it goes in.

Adjusts deposit amounts

It can adjust token amounts when liquidity is added.

Runs at pool creation

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

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.

Safety report

Automated checks, not an audit

!Has an adminowner() is 0x2580…f7c7. 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 publishedThe code on the block explorer matches what's deployed (contract: BrownieHook).

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