Pyre

EthereumRegistered

Pyre is a Uniswap v4 hook bundled with an ERC20 token (v4PYRE) that levies a 15% ETH tax on both buys and sells. On buys (ETH→v4PYRE), it skims 15% of the ETH input via beforeSwap delta; on sells (v4PYRE→ETH), it skims 15% of ETH output via afterSwap delta. All tax proceeds are forwarded to a hardcoded treasury address.

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.
