Chat SDK Now Supports XChat

Key point

The Chat SDK now supports the XChat adapter, enabling the development of encrypted chat bots.

Details

Vercel's Chat SDK now supports a new XChat adapter, allowing developers to build 1:1 and group chat bots with end-to-end encryption (E2EE) on the XChat platform.

This adapter automatically handles encryption, key management, and signature verification, reducing the development burden. Additionally, if a user has set up encrypted chat and is following the bot, the bot can initiate messages.

Since XChat does not support Markdown rendering, the adapter handles this automatically:

  • URLs and @mentions are converted into tappable links
  • Tables are displayed as ASCII code blocks
  • Cards are converted into text with link previews
  • Streaming is implemented via message edits
