Recognizing Real Fandom
Each shirt in the drop is signed by player from the European champions, PSG, embedded with Cifr’s patented and unclonable NFC chip, and connected to the winner’s MatchID, creating a verifiable link between the physical item and a real person on-chain.
“We’re teaming up with Cifr to show how physical products can unlock digital experiences,” said Petrix Barbosa, CEO at Matchain. “These shirts don’t just prove they’re real — they prove who they belong to, and open up new ways to engage.”
The experience extends beyond the drop. Shirts unlock exclusive PSG content when tapped and act as access passes for future drops, perks, and events.
