Tangem sells card-shaped and ring-shaped hardware wallets that let people store their own cryptocurrency safely and tap a phone to use it.
Tangem makes hardware crypto wallets the size and shape of a credit card, plus a ring version you wear on your finger. Instead of remembering long passwords or writing down secret recovery phrases, you just tap the card or ring on your phone and the wallet works. The company's pitch is simple: self-custody, meaning you hold your own crypto rather than trusting an exchange, but without the usual headache of safeguarding keys.
A hardware wallet is a small physical device that keeps your crypto's secret keys offline so hackers can't grab them over the internet. Tangem's twist is that each card or ring contains a secure chip, and the keys are generated inside that chip and never leave it. Setup takes about three taps. You can buy a pack of cards, keep one on you and stash the others as backups, and use them via a phone app. The company sells these directly to individuals through its own store and retail partners, and it earns money from the hardware itself plus optional add-ons. Tangem's chosen niche is convenience. Traditional wallets like those from Ledger require a separate device, a cable, and a recovery phrase written on paper, which is safer but clunky. Tangem bets that most people want protection that feels as easy as tapping a payment card. That trade-off is also its vulnerability: a wallet with no recovery phrase is only as good as the physical cards you keep, so losing all of them means losing the crypto. The company has grown fast on the back of the crypto boom and markets itself as a simple bridge for newcomers who want self-custody without the friction.
The business is young and private, based in Zug, Switzerland, a hub for crypto and blockchain firms. It has struck partnerships and shipped millions of cards, and it keeps adding products like the ring. Because it sells physical goods, revenue rises and falls with crypto enthusiasm and the price of bitcoin, and its real test is whether it can turn a one-time hardware sale into a lasting relationship with customers.
