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.

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.
