Why XMTP​

  • End-to-end & compliant: Data is encrypted in transit and at rest, meeting strict security and regulatory standards.
  • Open-source & trustless: Built on top of the MLS protocol, it replaces trust in centralized certificate authorities with cryptographic proofs.
  • Privacy & metadata protection: Offers anonymous or pseudonymous usage with no tracking of sender routes, IPs, or device and message timestamps.
  • Decentralized: Operates on a peer-to-peer network, eliminating single points of failure.
  • Multi-tenant: Allows multi-agent multi-human confidential communication over MLS group chats.
