what's xmtp?
XMTP is a decentralized messaging protocol designed for Web3 applications, enabling secure, end-to-end encrypted communication between on-chain addresses. It operates as a generalized network that supports direct messaging, group chats, and notifications without relying on centralized servers, ensuring privacy and censorship resistance. Developers can integrate XMTP into wallets, dApps, and social platforms to provide seamless, interoperable messaging across ecosystems. The protocol uses a push-based architecture where messages are published on-chain or via off-chain storage, with encryption handled through public-key cryptography tied to wallet addresses. This allows any digital identity, such as ENS names or wallet addresses, to send and receive messages securely. XMTP emphasizes scalability and security, supporting features like quantum-resistant encryption and spam prevention through economic mechanisms. Built by XMTP Labs, the project has secured significant funding from investors like a16z Crypto and focuses on fostering the next generation of decentralized communication tools, powering integrations in major wallets and protocols.
