# Pass Contract

### Purpose <a href="#purpose" id="purpose"></a>

`Pass` extends from `ERC721` (an OpenZeppelin implementation of the ERC721 standard for NFTs), [`AffiliateMember`](broken://pages/Dwc1KYSIDgCR2f0JIdMH), and `ReentrancyGuard`. Its main functionality is to mint NFT passes for members of the affiliate system, ensuring unique ownership and adherence to specific conditions set by the affiliate system.

The Pass NFT is a soulbound (non-transferable and non-burnable) token that acts as a permanent membership card. It is mandatory for betting, depositing, and inviting others.
