A key that can open
any door in the world.
Secret Key mints custom physical Keys — precision coins carrying a QR code you control. Change where your Key points at any time, track every scan, and hand people something they will never throw away.
Minted to last
Each Key is a precision-minted coin carrying your artwork — a physical object people keep, not a card they throw away.
A code you control
Every Key carries a QR code that points wherever you choose — and you can change the destination at any time, long after the metal is struck.
Every scan counted
See when and where your Keys are scanned, with clear metrics and exports from your own portal.
How it works
- Design. Bring your art or work with us to design your Key and its QR code — colors, imagery, finish.
- Mint. We mint your Keys and ship them to you, ready to hand out, sell, or send.
- Share. Every scan routes through your own Secret Key link and lands wherever you point it.
- Repoint. New album, new menu, new campaign? Update the destination in seconds. The Key never expires.
