XMTP (Extensible Message Transport Protocol) is an open protocol and network for secure, private messaging between Ethereum accounts. With the XMTP SDK, developers can enhance their applications with a universal inbox for direct messages, alerts, and announcements, or build new tools for dapps, DAOs, creators, and protocols to re-engage users via web3 messaging. Its primary contributor, XMTP Labs, is funded by some of the industry’s top venture capital funds including a16z Crypto and Coinbase Ventures.
