TaxHookApplies a time-decaying buy/sell tax on the ETH leg of swaps in a native ETH/token pool, forwarding collected ETH to an immutable dev wallet. The tax rate steps down by 100 bps per configurable interval from the pool's launch timestamp until it reaches 0%.

MemeFeeHookCharges a fixed 4% fee on all swaps in ETH-paired pools (currency0 = native ETH), always denominating the fee in ETH and routing it directly to an immutable treasury address. The fee is taken in beforeSwap when ETH is the specified currency and in afterSwap otherwise, using return-delta hooks.

HalloMarketsFeeHookA volatility-based dynamic fee hook for HalloMarkets launchpad pools. Charges ETH fees between 1–5% on buys (via beforeSwap delta on input) and sells (via afterSwap delta on output), scaling the fee based on the tick movement of the previous swap. Fees are sent directly to a per-pool fee recipient on every swap.
