HHook

EthereumRegistered

A Uniswap v4 hook implementing a floor-price defense and tax system for an H/ETH pool. When the AMM spot price falls below the treasury-backed RFV, beforeSwap intercepts exact-input H sells and redeems them at RFV directly from the treasury (burning the H). A 3% swap tax applies on all non-intercepted swaps—burning H on buys and routing ETH to the treasury on sells—with additional bonding and epoch-based staking rebase mechanics.

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.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
