An NFT whitelist is simply a list of wallet addresses of users who have been supporting the project since its inception. These users are carefully chosen and receive perks like early access to an NFT collection before it is launched to the general public. Furthermore, those on the waitlist can get their NFTs at a lower transaction fee. This helps ensure that gas wars are minimised and that true patrons are the ones who can get the NFT, making the whole system much more fair. And just as NFT platforms can range from art to cricket NFT marketplaces, the eligibility criteria to join the waitlist can differ with the platform.
