The term whitelist can have many meanings in the crypto sector. In general, a whitelist refers to a list of individuals, wallet addresses, or entities deemed to be trustworthy.
Whitelists may relate to initial coin offerings (ICOs) and new non-fungible token (NFT) projects. Investors who want to participate in some ICO may be required to be whitelisted by providing their personal information. This might give them early access to the tokens or NFTs of a particular project.
In the context of withdrawing cryptocurrency, a whitelist refers to a safe list of crypto wallet addresses. In this way, a whitelist is used as a security measure. Users can also whitelist website addresses, programs, or services they consider safe to use.
