Today, the core team behind the XMTP protocol and SDKs have officially merged the Production Release for XMTP v3.

This release is the foundation for a decentralized messaging protocol with a full suite of functionality & ✨ 30+✨ features hardened.

With this production release, 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
⚡ Scales for large groups
📱 Across multiple devices

Come build the most secure and private messaging network in the world—owned by the people who build it and use it.

As we work towards Mainnet (set for H2 2025) we have published a protocol roadmap.

Here, you’ll find the key improvement proposals we’re working on, organized by when they’re expected to land in stable production software.
