Platform Values
Why choose MarsCat?

We’re not just a chat app — we’re a digital free zone that truly belongs to users.
We reshape how value is distributed and where privacy boundaries are drawn in social networks.

True P2P network
Nodes connect directly without passing through a central server, so there is no single point of failure and no central hub that can be shut down.
Fully decentralized
MarsCat is powered by open protocols and its community; no individual or organization can control the entire network.
Privacy by default
All communications use end-to-end encryption by default, and only the participants can access the messages and data.
Security designed for the future
The network’s security model protects you today and is built to withstand tomorrow’s more powerful computing capabilities.
Your key is your identity
Your identity is defined by keys generated locally on your device, with no account registration and nothing the platform can revoke.
No phone number,email,KYC
We never ask you for any real-world identity information.
