Tethered Services embeds NFC authentication chips into physical assets.  Collectors verify authenticity by tapping a smartphone against the work.  Every scan logs provenance, ownership, and verification data for the life of the piece.

Built by artists who understand what creators need: control over public valuation, protection against fraud, and a permanent connection to every collector who owns their work.

Our internationally patent-pending dual-tag system pairs a public NFC chip embedded in the asset with a private chip in the Certificate of Authenticity.  Centralized trust infrastructure.  No blockchain complexity.  No market volatility.

Your artwork is not training data.  Our system authenticates through cryptographic verification on the object itself.  No images of your work are uploaded to AI models, stored in third-party databases, or used to train machine learning systems.  The authentication lives on the physical piece, not on someone else's server.

Tested live at Point Blanc, our gallery event series in New York, with real artists, real collectors, and real NFC-authenticated transactions.
