Contacts, OpenAlias and a better search.

Released 15 June 2026.

Contacts

Zkool has an address book. Contacts can be typed in, imported and exported as vCards, or imported from the phone's contacts, where Zkool looks for Zcash addresses in the notes, websites and social fields. A transaction to or from a contact shows the contact's name in the history, and the search bar finds it. On the send page, @ followed by a name picks a contact, with suggestions as you type, and ! followed by a name picks one of your own accounts. See the Payments guide.

OpenAlias

A recipient written as #alias is resolved through DNS, as OpenAlias specifies. The answer is validated with DNSSEC when the domain is signed; if it cannot be verified, Zkool says so and lets you abort.

Also

• The history search bar filters by memo and contact in the list and the table views alike.
• The chain height is cached for 15 seconds and not fetched when the app is offline.
• Errors from a Zebra server are reported rather than crashing the sync.
