Through this partnership, the Whopper team will work with KuCoin to create the world’s first custom KCS physical cold storage card, which will be collectible, giftable and tradable. A community voting campaign will be launched shortly with multiple card designs, with the winning design being made available for purchase soon after.
Whopper is a producer of custom high quality physical cold storage cards and public key deposit cards. Our automated production system, along with operating all our own equipment, ensures that all key pairs for cold storage are safe with multiple system checks to confirm safety in our system.
