hive keychain should have a messaging system, where you can send 0.001 hive and send a message that pops up in your keychain, in any of the accounts you have in there. so we can send emergency messages or ask to buy accounts or whatever, can just em a wallet transaction with a memo formatted a certain way and they can create notification alerts, and we can set our own notification price so u can only hear the notification alert if someoen sends you at least 0.1 hive or 1 hive or whatever
