BlacklistHook

EthereumRegistered

A Uniswap v4 hook that blocks token sells by default; wallets self-unlock by sending any ETH amount to the hook (immediately refunded). Applies a 3% ETH buy tax and a volume-tiered sell tax (3–10% over a 2-hour window) to an authorized ETH/token pool, with an on-chain lottery for buys ≥ 0.05 ETH.

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.
