Wallet Whitelisting
Wallet whitelisting is a security mechanism implemented by centralized exchanges and institutional custody platforms that restricts outbound asset transfers to a pre-approved list of blockchain addresses. By requiring users to manually verify and approve specific destination addresses, the platform creates a layer of protection against unauthorized withdrawals.
If a user account is compromised, the attacker cannot easily siphon funds to an arbitrary external wallet because the address is not on the approved list. This process often involves additional multi-factor authentication or a mandatory time delay to prevent immediate exploitation.
It is a vital risk management tool in the cryptocurrency ecosystem to protect institutional liquidity and retail user balances. The trade-off is reduced flexibility for users who frequently interact with new protocols or decentralized applications.
