The useful
details.
What does a hook change?+
A hook is a layer of custom logic around an AMM interaction. It can describe a fee policy, revenue rule or execution condition without turning the interface into a black box.
How does Launch Coin work?+
Launch Coin brings token metadata, hook policy and wallet selection into one review flow before you continue with your token setup.
How does an adaptive fee work?+
The builder linearly blends a 0.30% base fee with a 1.00% maximum fee as the activity slider moves from quiet to busy.
Can I export the policy?+
Exporting creates a portable launch brief with the selected metadata, fee rules and hook modules.
