Remember when no one
could listen in?
XMTP is the world's new private line. Send messages and money securely between people or agents — with no company or country in the middle.
Messaging today is the biggest surface on the internet. But it's closed to innovation and open to censorship.
That's why the future of communication must be decentralized.
We built XMTP to be quantum resistant, open source, identity agnostic, native to digital money, and spam resistant at the protocol level.
Everyone should be able to trust and own the messaging network they build on and use. Without a single person or company who owns it.
That's XMTP.

XMTP is securing the world's freedom to communicate
World combines Proof of Humanity with XMTP’s secure messaging, to create the world’s first verified human messaging network.
Tomorrow's apps have a voice
Connecting 55M users and thousands of developers on one messaging network
XMTP is the open layer for chat-based apps, connecting messengers, agents, and mini-apps into one permissionless network.
Builders can bring payments, apps, agents, and games to secure, programmable group chats to keep users engaged and drive transactions.
No app store rules. No API keys. No kill switch.

The secure messaging protocol
Unlocking an open, private, and decentralized foundation for secure communication
Quantum-resistant, end-to-end encryption
XMTP uses quantum-resistant hybrid encryption to protect against "Harvest Now, Decrypt Later" attacks and provides perfect forward secrecy and post-compromise security, ensuring messages can never be retroactively decrypted. XMTP's MLS implementation was fully audited by the same cryptography firm that reviews Signal and WhatsApp.

XMTP works with any decentralized identifier (DID) or network identity. Developers simply connect their existing identity model to XMTP, allowing users to message securely using passkeys, wallets, social accounts, or custom identities with no platform lock-in.

XMTP supports native integration of digital currencies and assets. Users can send tokens securely in conversations, agents can manage transactions, and services can embed payments. As an open protocol, XMTP makes it straightforward to integrate digital assets into messaging experiences.

XMTP's network level consent provides end-users with the ability to allow or block anyone across the XMTP network. Everything is opt-in, encrypted and controlled by users. This provides developers with a network level view of allowed/blocked senders, helping to create spam free experiences for users.

A token-based messaging network that sustains itself
App developers pay approximately 5 USDC per 100,000 messages to use XMTP. This fee covers the infrastructure costs of independent node operators who deliver messages across the network.
Nodes are globally distributed so that the network keeps operating even if any country changes its stance on privacy and encryption.
Don't trust, Verify.
Open sourced everything.
XMTP is open source from the ground up, from nodes and smart contracts to SDKs and example apps. Everything is public, auditable, and built together with the community because you shouldn't have to trust one company's word when it comes to the security of your communication.
We fundamentally believe that the most private network is the one where nothing is hidden.
