Authenticity as a Protocol

giansanto_ was born from the idea that quality clothing deserves an authentication system worthy of it. Not a hologram that can be photocopied, not a QR code that can be screenshotted. A real cryptographic protocol, integrated into the very fabric of the garment.

From Taranto to the World

We are AQuattordici srls, an Italian company based in Taranto. The giansanto_ project was born from the convergence of two passions: quality streetwear and cryptographic technology. We spent months studying military-grade NFC chips, the Polygon blockchain, and SUN/SDM authentication protocols before sewing the first prototype. The Genesis Collection is our first step: 30 numbered t-shirts, each with an NTAG 424 DNA chip heat-sealed on the chest and an NFT on Polygon. This is not an experiment — it's a working protocol, verifiable by anyone with a smartphone.

Our Mission

We believe that every valuable garment should have a verifiable digital identity. Not for fashion, but out of necessity. The counterfeit market is worth billions, and current solutions (holograms, static QR codes, paper certificates) are easily replicable. giansanto_ proposes a different approach: hardware-level cryptography. Every NFC tag scan generates a unique signature that cannot be cloned, copied, or forged. The counter increases with each read. The blockchain records everything immutably.

Our Values

Real Authenticity

Not holograms or QR codes. AES-128 hardware-level cryptography, verifiable by anyone.

Open Technology

Our protocol is transparent. Anyone can verify authenticity with a smartphone.

Limited Edition

Every collection is numbered. No overproduction, no waste.
