Police Hook

EthereumRegistered

Applies asymmetric fees to an ETH/token pool: 0% on buys (ETH→token), 5% on sells (token→ETH). On sells, the ETH fee is routed to the paired token contract via poolManager.take() and token.notifyEthFee(). Also validates that tx.origin holds sufficient token balance before allowing exact-output sell swaps.

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.
