HaloHook

EthereumRegistered

HaloHook implements a phase-based ETH tax system for a token launch, extracting 3–30% from buys and sells via hook deltas with a time-decaying ignition period. Buy taxes are partially accrued as claimable refunds, released only if the buyer holds their token position for a minimum block window after purchase.

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.
