Invariant

$XYK
x · y = k
the constant product

Every automated market maker since 2018 has obeyed one equation. Liquidity arrives and leaves. Price moves. Traders come and go. k does not care.

An invariant is not a promise or a roadmap. It is the property of a system that holds regardless of what happens inside it. That is the whole idea, and there is nothing else to explain.
