/**
Welcome to Charmander Tech 🔥

Charmander brings burn mechanics that stops sell pressure, reduces supply and ensures maximum moon, 
through the use of the CHARM dApp. These burnomics make sure there are no fees when you burning 
(like you would do selling), no impact on the chart and a deflationary supply!
