The world’s first ring-shaped cold wallet. Fashion statement or a revolution in crypto security? After testing it, here’s everything you need to know.
What is the Tangem Ring?
Tangem has created something that did not exist until now: the world’s first ring-shaped cold wallet. It brings the security technology of a traditional hardware wallet into an accessory that fits on your finger, with no screen, no battery, and no internet connection. That last point is exactly what you want in a cold wallet: your assets remain completely isolated from any online threats.
The operation is as simple as its design. You take it off, bring it close to your phone, open the Tangem app, and instantly access your cryptocurrencies via NFC, the same technology used when paying with your phone at a supermarket. And when you are not using it, it is simply a ring on your hand. No one knows what you are wearing.
Design and Materials: When Safety Becomes Jewelry
One of the most striking aspects of the Tangem Ring is how it combines security and design in an elegant, fully functional everyday form factor. More than just a technological device, it feels like wearing a premium piece of jewelry designed to accompany you in any situation.
This is one of the Tangem Ring’s strongest points. It does not look like a piece of technology. It looks like a real ring.
It is made from high-purity zirconia ceramic, a hypoallergenic material that is extremely durable and has a finish that feels more like a piece of jewelry than a gadget. It measures between 7.8 and 8 mm in width, making it discreet and comfortable for everyday wear.
The certification IP69K It protects against:
- Scratches
- Dust
- Water and submersion
- Extreme temperatures
To give you an idea, IP69K is one of the highest resistance ratings available, even more advanced than IP68 found in most luxury watches and premium smartphones. This means you can shower with it, go to the gym, and work with your hands, and the ring will handle it without any issues.
The result is a cold wallet that no one would recognize as such. No one knows you’re keeping your Bitcoin in there. That discretion is, in itself, an extra layer of security.
Security: the true strength of the Tangem Ring
Beyond its design, security is what truly gives the Tangem Ring its purpose. The ring includes an EAL6+ Common Criteria certified chip, the same standard used in biometric passports and high-security banking systems. The private key is generated directly inside the chip during activation and never leaves the device or gets exposed to the internet, which is exactly the foundation of any true cold wallet.
Tangem also eliminates much of the typical attack surface found in this type of product: the firmware cannot be updated, which avoids risks related to malicious updates, and the entire system has been independently audited by firms such as Kudelski Security and Riscure. On top of that, there is a particularly smart detail in everyday use: NFC does not function properly while you are wearing the ring, so you must physically remove it and approve access through the app using biometrics or a passcode before signing any transaction.
Price and what it actually includes
Currently, the Tangem Ring is officially priced at $112.50 and includes the ring itself along with two Tangem backup cards, plus free shipping. The company also offers traditional card packs starting at $49.41 and a more complete Tangem Pro Kit for $162 for users who want additional devices or extra backup options.
In terms of price, the Tangem Ring sits within the typical range of premium hardware wallets. The main difference compared to other models is its wearable form factor and the fact that backup cards are included by default. Tangem also frequently offers temporary discounts directly on its official website, so the final price may vary depending on the promotion available at the time of purchase.
The positive aspect is that there are no subscriptions or additional hardware costs: you pay once for the device, and the app is completely free.

Choosing the correct size is critical, because once the wallet is set up, the ring cannot be exchanged for another one without going through the return process. Tangem provides an official PDF sizing guide and a tutorial on YouTube specifically for this purpose.
Available sizes range from US size 6 to 13. To convert:
| US Size | Inside Diameter (mm) | Inside Circumference (mm) |
|---|---|---|
| 6 | 16.51 | 51.87 |
| 7 | 17.35 | 54.51 |
| 8 | 18.19 | 57.15 |
| 9 | 18.89 | 59.34 |
| 10 | 19.84 | 62.33 |
| 11 | 20.68 | 64.97 |
| 12 | 21.49 | 67.51 |
| 13 | 22.33 | 70.15 |
Measurements may vary slightly (±0.25 mm) due to the zirconium ceramic polishing process.
The easiest method is to measure the inner diameter of a ring that already fits you well, or wrap a strip of paper around your finger and compare the measurement with Tangem’s official sizing guide. If you are unsure between two sizes, the brand recommends choosing the larger one.
How it works: step-by-step guide
The setup process takes less than 3 minutes:
1. Download the Tangem app Available on both the App Store and Google Play. It is free.
2. Scan the ring Take the ring off your finger and bring it close to the back of your phone (where the NFC reader is). The app will detect it automatically.
3. Create your wallet The app guides you through the wallet setup. At this stage, the chip generates a random private key that will be stored on the device.
4. Set up your backups This is one of the smartest parts of the system: the pack includes the ring plus two backup cards. You can configure it in two ways:
- Option A: 1 ring + 2 backups → A single wallet with three access devices.
- Option B: 3 independent wallets → One for each device.
The private key is replicated securely between the three devices. There is no other copy in the world, neither in the cloud nor on any server.
5. Add your cryptocurrencies From the app, you can manage Bitcoin, Ethereum, Solana, XRP, Tether, and over 6,000 tokens across different networks. The same interface as any other wallet, but with the security of a cold wallet.
What happens if I lose the ring? Your funds remain safe. You can access them through the backup cards. Whoever finds the ring cannot do anything without your access code and the configured app.
Who is the Tangem Ring for?
If you hold cryptocurrencies long-term and are looking for maximum security without carrying a bulky device, the Tangem Ring is made for you. It combines the protection of a cold wallet with the convenience of wearing it at all times, and its ceramic design makes it completely unnoticeable. It's security that you can't see, And that, in the crypto world, has enormous value.
- Hodler of BTC, ETH, SOL or other cryptos that you prioritize protecting against hacks.
- People who value privacy and don't want it known what they are carrying.
- Active lifestyle: sports, travel, physical labor. The IP69K handles it all.
- Those looking for an elegant and wearable alternative to a Ledger or Trezor.
- Premium gift for someone in the crypto ecosystem.
It's not the ideal option if you operate at high frequency and need to confirm each transaction on an integrated physical screen.
Final Opinion: Is the Tangem Ring worth it?
The Tangem Ring makes sense for a very specific type of user: someone who wants the security of a cold wallet but does not want to rely on a device that is inconvenient to carry or use in daily life. The entire concept is built around this idea: maintaining self-custody and offline protection of private keys, but in a much more discreet, portable, and natural-to-use form factor.
And that is exactly where the product works especially well. Being able to carry the wallet with you at all times, with no cables, no battery, and without anyone identifying it as a crypto device, significantly changes the experience compared to a traditional hardware wallet. On top of that, it includes a well-designed backup system, premium materials, and an extremely simple setup process, even for users who have never used self-custody before.
After testing it, the impression is clear: the Tangem Ring does not try to impress with technical complexity, but rather aims to make crypto security more comfortable, practical, and easier to integrate into everyday life. And for the type of user looking for exactly that, it is likely one of the most interesting options available right now.
Before making a decision, you can read the full analysis of the Tangem Wallet to understand how it fits within the self-custody ecosystem:
This review is based on a one-month real-world testing period. During that time, we set up the wallet from scratch following the official process, tested the backup system with multiple cards, made transactions and received funds across different networks (Bitcoin, Ethereum, and Solana), and evaluated the day-to-day experience of carrying it in a wallet and using it with different Android and iOS devices. We also checked how the app behaves across different operating system versions and tested NFC response speed under normal usage conditions. The result you are reading reflects an accumulated experience, not a first impression.
Excellent Purchase!!!
Hello, could you do a detailed review for those of us who just want the card? Thanks
It looks really good, honestly. It's funny that it's a ring, haha.
Aesthetically, the ring is a marvel
