The engine underneath.
Your experience on top.

Cellact is the company building communication infrastructure and products. Arnacon is our communication engine: it connects identities, applications and provider networks. The Arnacon app puts that engine to work for calls and messages. You can build your own experience on it, too.

Identity is the starting point.
One foundation. Different possibilities.

Built from
the inside out.

Read the stack from the foundation upwards: wallet tools, the communication engine, then the app and its services. The chip represents software, not hardware you need to install.

Build on the foundation ↗

Arnacon provides the shared communication infrastructure. The app provides the interface; SecNum adds a second number and LightPBX adds business calling inside it. This is a conceptual software diagram, not a physical device.
