LaunchTokenV4

EthereumRegistered

ERC20 token with a built-in Uniswap v4 hook that collects configurable buy and sell taxes in ETH. On buys (ETH→token), a percentage of the input ETH is taken before the swap via beforeSwap; on sells (token→ETH), a percentage of the ETH output is taken after the swap via afterSwap. Both taxes are forwarded immediately to an immutable tax wallet.

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
