One high severity issue was found regarding reentrancy in Raffle with ERC1155 tokens in some cases. A wrapper contract was implemented to wrap ERC1155 to ERC721 tokens to use in the Raffle. The contracts are highly dependent on the owner’s account. Users using the project have to trust the owner and that the owner's account is properly secured.

Audit includes recommendations on the code improving and preventing potential attacks.
