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.

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.

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.
July 10, 2025 at 3:26 PM
As of today, XMTP is now a fully quantum-resistant decentralized messaging protocol.

This means, any developer, anywhere in the world can leverage XMTP to provide their users with private, decentralized, & quantum-resistant messaging.

To build a new communication network that requires global trust, you have to open source everything. True security comes from transparency.

This is why XMTP's node software is open source—anyone can inspect, & verify every line of code. No more blind trust in a black box.

One inbox. Many identities.

XMTP lets users link multiple identities + passkey or crypto wallet to a single secure inbox.

This means any DiD, can link to XMTP and access secure, private messaging with XMTP.

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.

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

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

Our core pillars are:
✅ Secure, audited encryption
✅ Full-stack transparency
✅ Global decentralization

Decentralized messaging means we own & control our messages, the way we own and control our money.

Privacy is under attack.

🇬🇧 The UK made Apple drop ADP.
🇮🇳 India forced a backdoor to WhatsApp.
🇷🇺 Russia & 🇹🇷 Turkey banned Discord.

Centralized systems are breaking down & encryption is not enough.
We need decentralized messaging.
