Cryptoballs are erc721 NFT divided into two categories,
Collectibles based on the Ethereum network and sending NFT items, called expressballs based on Polygon network.
In this way, users will have the possibility to decide whether they want to buy personal collectible balls or expressballs, to be sent to others.
We chose two different networks in order to allow customers to send balls without having large charge of fee.
Users who purchase collectible cryptoballs will also receive the “send copy” on Polygon!
