Fecret Santa is a twist of the classic "Secret Santa" event. This new version is based on a "chain" (pun intended): someone will gift a collectible (ERC721 or ERC1155) to the last Santa, they'll become the last Santa themselves and will receive the next gift, and so on!
The whole project was built in Fe during this Hackathon, you can have a look at the code here. The repository is a "custom" Fe project that comes with Foundry, this allowed me to write tests in Solidity and deploy multiple mock contracts (ERC721 and ERC1155) to try out things.
Check out the repository on Github for technical details!
