Quick Setup (< 1 hour)

You can use XMTP to build secure, decentralized messaging into your app or service. It lets developers add end-to-end encrypted chat that works across different identities like crypto wallets, passkeys, and social accounts. Messages are quantum-resistant, meaning they are protected against future decryption attacks. You can embed payments directly in chats, build group messaging with mini-apps, and let users control who can contact them. No single company owns the network, and node operators worldwide keep it running.
