XMTP (Extensible Message Transport Protocol) is the leading decentralized, end-to-end encrypted messaging network for Web3. Built on the IETF-standard MLS protocol, it enables secure, portable messaging across wallets and apps with full user control and spam protection. Supporting over 2 million identities and 60+ apps, XMTP powers DMs, group chats, and notifications across protocols like ENS, Lens, and Farcaster. Ephemera is one of the flagship apps built on XMTP—focused on privacy-first messaging and token-enabled payments. XMTP’s open-source SDKs and decentralized architecture make it the messaging backbone for the Web3 ecosystem.
