Trusted address book protection is a security feature on Coinbase Prime that only allows crypto withdrawals to external addresses listed in your portfolio's address book. It also allows you to label withdrawal addresses so they're easier to find.
This feature is automatically enabled for all portfolios. Updates to your address book are subject to consensus approvals. New external addresses must be approved before you can send to or withdraw from the address.
