In GRVT, the Address Book is a security feature that ensures assets from your GRVT Funding Account can only be transferred to pre-approved recipients. Pre-approved recipients can be other Funding Accounts within GRVT or addresses in public networks supported for GRVT withdrawals. This means, transferring funds to either other GRVT accounts or an address in a public network like Ethereum require the address to be in the Address Book already before the external transfer or withdrawal request is initiated.

To register a recipient on the Address Book, you can navigate to My Account > Address Book.
​

Note: For Business Accounts, adding a recipient on the Address Book requires sign-offs from the Funding Admin(s) as per the multi-signature threshold in place.
