Discover the WhatsApp for web3: end-to-end encrypted messages between wallets, that only you own and can take with you anywhere.

With Notifi, XMTP in-app messages can now trigger notifications to any web2 app, so devs can reliably reach their end-users without compromising on security.
This post may be out of date. See the Attachments tutorial for the latest guidance on how to build attachments.
Let's talk about some new content types for XMTP.
What's a content type? A content type is a way to describe the type of content a message contains on XMTP. Out of the box, XMTP's SDKs support one content type: text.
Here's the thing though: messaging has been more than just text since way back in 2002, when your LG VX8100 was blowing up from MMS.
So we decided to propose some new content types: Attachment and RemoteAttachment. These new content types support rich media (images, videos, gifs, etc.) and will let you bring your messaging experience to the cutting edges of the early aughts.


If you’ve been in the web3/crypto community for longer than an hour, you’ve probably seen a strange message that seems to accompany every Discord server. Something that looks like this:

Announcing XMTP Grants! A program to nurture web3 messaging projects, support public good creation, and foster ecosystem growth.

This holiday season, we have an early gift for all the web3 developers out there. Our mobile SDKs are now available in Developer Preview 🧑💻

With XMTP, meTokens enables all creators to coordinate in a privacy-based manner that is simple enough to create widespread adoption.

"Wow" is just about the best way we could sum up @ETHGlobal's #ETHSanFrancisco.

XMTP and Lens hosted a 𝕏 Spaces event on November 10 to dig into how developers can now use XMTP to add E2EE DMs into their Lens apps.
