About
XMTP Labs is the primary contributor to XMTP (Extensible Message Transport Protocol), a decentralized messaging protocol that enables quantum-resistant, end-to-end encrypted communication between any blockchain wallet, passkey, or digital identity. The network supports 1:1 and group messaging, in-chat payments, and programmable mini-apps—without any central server or API gatekeeper. XMTP Labs' open-source node network is globally distributed and fully audited by the same cryptography firm that reviews Signal and WhatsApp. The company also develops Convos, a next-generation messaging app built on the protocol.
