Use Cases
How apps and wallets use XMTP
Learn about the connected and resilient ecosystem for seamless communication across apps and wallets
Security
Enterprise-grade encryption
Built on the IETF-standard Messaging Layer Security (MLS) protocol – the same open-source security foundation trusted by Mozilla, Google, Wire, and Cisco. XMTP's fully audited implementation provides perfect forward secrecy and post-compromise security, ensuring messages can never be retroactively decrypted.
Identity
Flexible identity foundation
Turn any collection of wallet addresses into a unified messaging identity. Support the full spectrum of web3 identities — from naming systems (ENS, Base, Lens) to social platforms (Farcaster, Lens) to smart accounts (Safe, ERC-4337 wallets) — through simple wallet signatures.
Consent
Built-in spam protection
Users block spam once, and it's blocked everywhere they go. Your app automatically inherits spam protection that works across the entire XMTP network — giving every user control of who can message them.
Decentralization
Unruggable infrastructure
Your messaging infrastructure keeps running independently of any single operator or organization. No central authority can change the rules, revoke access, or shut down the service your users depend on.
XMTP is open source
The entire XMTP stack — protocol, apps, and developer tools — is fully open to inspect, modify, and improve, creating a trustworthy foundation for developers to build on with confidence.
