Secreth Santa

Secreth Santa allows anyone to send and receive Non-Fungible Tokens (ERC-721) as presents! The system is queue-based, everyone can join by sending an NFT to the last Santa, then they will receive later a new NFT sent by the next Santa! Additionally, if the last Santa hasn't received any present after 3 days, he can claim the "prize"! The prize consists in a collection of NFTs donated by various users and projects.
