NIP-A4 defines public messages (kind 24) designed for notification screens, with broad client support as a goal.

How It Works

Unlike threaded conversations, these messages have no concept of chat history or message chains. They’re simple one-off messages intended to appear in a recipient’s notification feed.

Structure

  • Uses q tags (quotations) rather than e tags to avoid threading complications
  • No conversation state or history
  • Designed for simple public notifications

Use Cases

  • Public acknowledgments or shoutouts
  • Broadcast messages to a user
  • Notifications that don’t need reply threading
