What is a Whitelist?
A whitelist is a list of wallet addresses set up by the NFT collection founders to grant early access to their collection before its launch. When a project is launched, those wallet addresses that are on the whitelist will get the chance to ‘mint’ (i.e., buy or claim) the NFT before anyone else.
Usually, whitelisted wallets can mint the NFTs at lower prices or even for free. Whitelists are set up to reward users who are committed to the project, who have been loyal and supported the project. The Whitelist sale is typically followed by a public sale, where general public is able to mint NFTs from the collection.
