Welcome to Parabolic
The token that's been designed to EXPLODE!
Super addictive game and tokenomics carefully engineered to do nothing but pump the chart! Let’s go parabolic!

It’s in the Name!
Parabolic Token has been carefully designed to achieve a single purpose – GOING PARABOLIC!
Our super addictive game and tokenomics will benefit the coin and consistently take it to new heights. Our game will be released in November, so don’t miss your chance to get in early!

There are NO team tokens and NO ridiculously high taxes! Every single penny of tax collected gets pumped straight back into the project.
Please read through our website to find out more, or join our telegram and ask any questions you may have.
