The question we’ve been asked most this week: is it safe to buy a Tangem from a reseller? 🎉Yes. Supply chain attacks simply don’t apply to a Tangem card. Here’s why. 1. A Tangem card has no "outside." The secure chip and NFC antenna are sealed into a single monolithic card. There's no screen, battery, port or internal wiring to tap, and no room or power for an implant: the card only draws power from your phone during the few seconds of a tap. In a seedless setup, private keys are generated inside the chip, never leave it, and every transaction is signed on the chip. The only data that crosses the NFC link is an unsigned transaction going in and a signature coming out, both of which end up public on the blockchain anyway. There is no secret in transit to intercept. 2. That's also why Tangem's authenticity check covers what matters. The Tangem app challenges the chip with a cryptographic test that only a card produced by Tangem, running Tangem's original firmware, can pass. That firmware is written to the chip once at the factory and can't be updated by anyone afterward, so it can't be swapped in transit. The app also tells you if the card was activated before it reached you, so nobody can hand you a wallet with keys they generated in advance. If you ever see that message, reset the card and the chip will create brand-new keys that only you control. Because the check covers the chip, and the chip is the whole wallet, where you bought your Tangem doesn't change your security. That includes cards bought through CryptoBilis. So it doesn’t matter where you buy your Tangem: our official store, any of our resellers, Amazon, Best Buy, Walmart, or even a stranger in an underpass. If the app says the card is genuine, it’s yours and only yours. We greatly appreciate our resellers' efforts to promote Tangem's mass adoption! They are in 200+ countries across every continent. Simply Tangem. 🫡
