Every agent platform solves for intelligence. Almost none solve for trust. XMTP is the communication layer for agents on the open web: 🪪 Verified identities 📋 Permissions 👥 Humans-in-the-loop 📒 Shared state Trusted agentic messaging.

💯 agree - it requires that we land on a standardized protocol for DM / GMs based on atproto IDs. All the same arguments for why AT Protocol was developed apply to the communications protocol. Needs to be open source and auditable. Closet we have to this right now is: bsky.app/profile/xmtp...

Today, @bsky.app + @atprotocol.dev devs can plug into XMTP to give users what they've been asking for: quantum-encrypted, secure group chats that scale to millions. With our XMTPID identity model, it's finally here. 1/5

Wave just added support for ATProto identities, becoming the first quantum-secure group chat app that connects ATProto identities with any other identity, secured by XMTP. That means any Bluesky, Blacksky, or XMTP identity can now join fully secure, interoperable group chats.

@xmtp.org

This isn’t just app-level messaging. @wavemsg.app is built on a shared, secure network layer on XMTP where group chats are: • End-to-end encrypted • Quantum-resistant • Privacy-preserving by design • Interoperable with any DID on XMTP

We’ve been building towards this moment for the past 5 years. • 2022 → Secure DMs • 2024 → Scalable group chats on MLS • Today → Scalable group chats w/ quantum-encryption for ANY DID with passkeys • 2026/2027 → Fully decentralized infrastructure for any DID 4/5

@xmtp.org

We built XMTP to work with any open identity standard. @bsky.app + @atprotocol.dev is just the first example. Any identity system with DIDs can plug in the same way. This is how we build truly open, interoperable communication: protocol-first, identity-agnostic, decentralized infrastructure. 5/5

🥷 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.

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.

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.
