When you whitelist an address in the Fireblocks Console, Fireblocks can show who controls that address before you finish adding it.
What you see
If Address Registry is enabled for your workspace, Fireblocks looks up the address while you add it. When there is a match, the Console shows the legal entity name, Legal Entity Identifier (LEI), and jurisdiction. If there is no match, the address appears as before. The whitelist steps themselves do not change.
API
If you whitelist through the API, call the Address Registry endpoint in that flow to get the same lookup.
