The onchain operating system
you truly own.
CubeOS powers the Cube Sovereign Phone — self-custody at the core, data-free by default, private by design. Your phone, your keys, your world.
A New Kind of Operating System
Every other phone runs on someone else's rules. CubeOS runs on yours.
Identity, payments, apps and security — all native to the chain, all controlled by you. No surveillance. No middlemen. No compromise.
Your keys live in the phone. Not the cloud.
One onchain identity and a self-custody wallet, built into the operating system. Sign, pay and prove who you are — without handing your data to anyone.
Free data, calls & messages — forever.
Connectivity is built into the OS. Browse Cube apps, make calls and send messages with zero data cost. No SIM games, no bill shock.
An assistant that builds, not just chats.
Cube AI lives in the OS. Ask it anything, automate your day, or describe an app and watch Studio ship it onchain — no code, no laptop.
Security & Privacy
Sovereignty isn't a setting.
It's the foundation.
CubeOS is hardened from the silicon up. Your identity, keys and data never leave the device — and nobody, not even us, can see them.
EAL6+ secure enclave
Hardware key vault isolates your wallet and identity from every app.
No surveillance
No ad IDs, no trackers, no data harvesting. Permissionless by you, opaque to everyone else.
Onchain provenance
Every transaction and permission is verifiable on the Cube chain. Nothing hidden, nothing forged.
