CupLink™ – Your privacy, uncompromised

CupLink™ offers a new paradigm in secure communication completely serverless, fully encrypted, and effortlessly private. Built on v6Space™, the decentralized IPv6 mesh overlay network, CupLink™ enables true peer-to-peer voice and video calling without accounts, servers, or surveillance.

Two Components. One Seamless Experience.

CupLink™ is composed of two integrated layers:

• VpN (Virtual Public Network)
A resilient, decentralized connectivity layer powered by v6Space™, enabling direct communication between devices—without tunneling, accounts, or centralized control.

• The CupLink™ App
An intuitive, lightweight calling interface that lets you connect instantly in full 4K+ resolution—encrypted end-to-end, key-based, and fully user-controlled.

Key Features

• Peer-to-peer video calling in crisp 4K+
• End-to-end encryption built directly into the network layer
• Self generated Virtual Static IPv6
• Access to Virtual Public Network (VpN) v6Space™
• Private Key-based identity management—no logins, no phone numbers
• Intelligent call-spy detection and real-time alerts
• Local encrypted backup
• Scan-to-connect simplicity—no setup, no sign-up required

Open-Source. Transparent. Auditable.

CupLink™ is licensed under GPL-3.0. With no telemetry, no data collection, and no proprietary black boxes, it remains fully transparent and community-audited.

Why Choose CupLink™?

Most apps route your calls through corporate servers and monetize your identity. CupLink™ does the opposite—removing the server, removing the account, and returning control to you. No ads. No tracking. No compromises.

Powered by v6Space™

v6Space™ is a decentralized, self-organizing IPv6 native overlay built by RiV Chain™. It serves as the backbone of CupLink™'s VpN layer, enabling direct, resilient peer to peer communication across mesh networks, local environments, and even offline scenarios without relying on centralized servers or tunneling protocols.
