Sphynx Protocol is building a decentralized ecosystem for meme tokens.

The sphynx cat is an energetic, acrobatic performer who loves to show off for attention. 
She has an unexpected sense of humor that is often at odds with her dour expression.
Friendly and loving, this is a loyal breed who will follow you around the house and try 
to involve herself in whatever you're doing, grabbing any opportunity to perch on your 
shoulder or curl up in your lap. 

Supply: 1,000,000,000
Tax Per Transaction: 3%
