CHAT YOU CAN BUILD ON

All of this runs on @xmtp_:

• End-to-end, quantum-encrypted group chats
• Open, decentralized messaging
• Identity-agnostic access run on a passkey
• Built for agents and apps
Privacy isn’t a promise. It’s the default.

DISCOVER MINI APPS

Mini apps run inside conversations and can be shared directly with a group.

Users don’t leave the chat.

Your mini app meets them where they already are.

AGENTS LIVE NATIVELY IN CHAT

Level up your group chat with adding @bankrbot

- Send money instantly to everyone in the chat
- Launch a token with friends
- Find a prediction market

CHAT IS THE NEW APP STORE

In Base App, chat isn’t a feature.

It’s where:
- Mini Apps are discovered
- Trading happens
- Money moves instantly
- Groups have fun

For builders, group chats are the new programmable surface area.

Any developer, anywhere in the world can get started building with the world's most private, secure, open messaging network.

👁️ Privacy through Transparency

As with everything in XMTP, this change will be released in the open. XMTP client code, servers, and data are available to the public. You can read a more detailed security analysis of the feature here.

github.com/xmtp/libxmtp...

XMTP was built on the belief that private communication must not depend on trust in any single party, including us.

We believe this architecture aligns with the highest privacy standards demanded by the most privacy-conscious organizations and individuals.

🥷 How XMTP defends against "Harvest Now, Decrypt Later"

Our partners at Cryspen have been working on a post-quantum OpenMLS, & have implemented hybrid ciphersuites that can be dropped in to replace all cryptography with post-quantum algorithms.

This now means no one can HNDL.

Quantum computing isn’t just sci-fi; it will break the cryptography we rely on for messaging.

While applications like Signal can protect at the application level, there has been no quantum-level secure open messaging protocol for developers.

XMTP is this solution for the world.

Messaging should be open, secure, and user-owned. Come & build with us to continue to make decentralized messaging a reality.

✅ Push notifications
✅ Disappearing messages

5/7

XMTP is more than a protocol, it's a network of apps & identities.

Meaning, the 2.2M identities on XMTP-- across @base, @ensdomains, @LC, @unstoppableweb & FIDs-- can use any app, such as @CoinbaseWallet, @family, or @converseapp_ (+ 60 other apps)

This is true ownership.

4/7

XMTP is the first decentralized implementation of the MLS (Messaging Layer Security), built entirely on the IETF's open standards.

🔒 E2EE encryption
👁️ Forward secrecy & post-compromise security
⚡ Efficient scale for large groups
📱 Support for multi-device messaging

3/7

XMTP ensures that no government, company, or individual has control.

Our core pillars are:
