👁️ 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.

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.

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.

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.
