What Is Coinfinity?

Coinfinity is a modular, Gridfinity-inspired system designed for organizing, storing, and tracking physical coin assets like gold, silver, platinum, and palladium. It features stackable containers (Stackers), magnetic bases and lids, and optional 25 mm NFC tag integration for identification, cataloging, and authentication.

About the MakerWorld Campaign

MakerWorld is a platform that enables creators to share and crowdfund 3D printable designs. Our campaign offers an opportunity for early supporters to back the Coinfinity project and gain access to our optimized models and print profiles.

Privacy & NFC

Your NFC tags are 100% private — they are not connected to a blockchain or centralized server. Tags are readable by any NFC-compatible phone using free apps.
