Nyan Balloon is a collection of floating cat NFTs living on the Ethereum blockchain. The collection was created by digital artist Chris Torres, also known as @PRguitarman. Chris is widely known for creating the iconic meme 'Nyan Cat' in 2011. Nyan Balloon is meant to offer a backstory to Nyan Cat and act as an explanation for how the famous feline made it into outer space.
The initial mint allowed buyers to mint a Nyan Balloon NFT featuring a Red balloon. However, during the final week of January, holders were able to exchange their Red Nyan Balloon for a different color balloon each day, ultimately resulting in 7 different Nyan Balloon colors.
