In the context of blockchain, the term “whitelist” has several meanings. First, it may refer to a list compiled by a blockchain startup to assess the legitimacy of potential investors who want to participate in an upcoming funding round based on identity verification and intended investment amounts. Second, it may refer to when cryptocurrency exchanges or wallets ask a user to “whitelist” a withdrawal address in order to verify its authenticity. This is done to protect the user from malicious actors making fraudulent withdrawals from their wallet or exchange account.
