AI summary

The article compares two leading air-gapped cold wallets in 2025: Tangem and Keystone, highlighting their fundamentally different approaches to security and usability. Tangem offers a seedless, NFC tap-to-sign model that prioritizes simplicity and eliminates the risks associated with seed phrases, while Keystone relies on traditional seed phrase backups and QR-code signing for greater transparency and control.

Cold wallets continue to set the standard for protecting digital assets in today's crypto space. We continue to pit Tangem against other popular crypto wallets in 2025 in our hardware wallet comparison series. This article compares both Tangem and Keystone; both offer air-gapped security without cables, but are built on very different philosophies. Tangem embraces a seedless, NFC tap-to-sign approach that removes the risks tied to seed phrases and QR codes. Keystone, by contrast, relies on a secure screen with QR-code signing, while still requiring users to safeguard a traditional recovery seed.

The Tangem vs Keystone debate goes beyond personal preference. It highlights two competing visions for cold storage security: Tangem's streamlined, recovery-free model versus Keystone's traditional seed phrase backups combined with visual verification.

What is Airgapping?

Airgapping is a security practice in which a device or system is kept completely isolated from the Internet or any external network. In crypto wallets, this means the private keys that control your funds are generated, stored, and used entirely offline, so they never touch the Internet, where hackers could steal them.

Instead of exposing the keys, the airgapped device signs transactions internally and only sends back the signed message, not the key itself. This way, even if your phone or computer is compromised, your private keys remain safe because they were never online in the first place.

Two Air-Gapped Wallets: Two Security Models

Tangem Wallet's NFC tap-to-sign technology is airgapped because the private keys never leave the card. When you tap it, the secure chip inside generates a signature directly on the card, and only that signature is transmitted to your phone. The card has no battery, Wi-Fi, or Bluetooth, so it cannot connect to the internet on its own, keeping the keys permanently offline while still letting you approve transactions with a simple tap.

On the other hand, Keystone wallets rely on a screen and QR-code system. They usually require you to handle a seed phrase, which is essential for wallet recovery and added security. Transactions are prepared by scanning QR codes with the wallet's camera, giving you a visual confirmation step that enhances security. Although this method might seem a bit more complex, it still gives you control over your private keys.

In short, Tangem provides a simple, easy-to-use approach with NFC technology and no seed phrases, focusing on convenience. Keystone, meanwhile, prioritizes security and control through a secure screen and QR codes, making seed phrase management an essential part of your security setup.

Tangem vs Keystone Compared

Backup & Recovery

One of the biggest differences between Tangem and Keystone is how each wallet handles backup and recovery. 
Instead of writing down or hiding a recovery phrase, users can easily create copies by adding extra Tangem cards during setup. Each card serves as a fully functional backup, making the recovery process straightforward and minimizing the risk of human error. This seedless method offers most users a safer and more user-friendly experience for most users, since losing or mishandling a seed phrase is the leading cause of wallet compromise.

Keystone, on the other hand, uses the traditional approach with 12 or 24-word seed phrases. It also supports Shamir backup, which divides the recovery phrase into multiple parts for extra security. Although this method offers more flexibility for advanced users, it places the full responsibility of securely storing recovery words on the user. In practice, a seedless backup system like Tangem's provides a safer user experience for 95% of users because it removes the need to safeguard paper phrases and reduces a common failure point in self-custody.

Security Comparison

When comparing Tangem and Keystone, the most important factor for most users is security. Both wallets are completely air-gapped, but take very different approaches to reducing risk. Tangem removes traditional entry points by design. Without a screen, QR interface, or ports, it minimizes its attack surface. Transactions are signed via NFC using the secure chip, making external exploits difficult. This simple model lowers potential vulnerabilities while keeping the signing process straightforward. Meanwhile, Keystone depends on QR-code signing through its built-in screen and external camera. Although this method offers transparency, allowing users to verify transactions visually, it also introduces reliance on firmware updates and external devices. The QR-based system carries risks of phishing and visual spoofing, where malicious actors could trick users into scanning fake codes or approving tampered transactions.

Ultimately, Tangem prefers minimalism to reduce its attack surface, while Keystone highlights visibility but carries the risks of QR-based workflows. The choice depends on whether you prioritize fewer potential entry points or the reassurance of on-screen transaction verification.

Usability & Setup

When comparing usability between Tangem and Keystone, the differences are immediately clear. Tangem provides an instant tap-to-sign experience with no setup required. You simply activate the card, pair it with your mobile wallet app, and you're ready to make transactions. There's no need for firmware updates, seed phrase writing, or complex onboarding—just straightforward, mobile-native simplicity. 
Keystone, on the other hand, involves a multi-step setup process. Users must initialize the device, record or back up their seed phrase, navigate the built-in screen, and occasionally install firmware updates. While this workflow offers additional control layers, it can feel time-consuming compared to Tangem's near plug-and-play approach. 
Tangem excels in simplicity, onboarding, and mobile-native design for everyday use, making it the more accessible option for most new users.

Price & Value

Pricing also plays a key role in comparing Tangem and Keystone. Tangem starts at about $59, and most bundles already include multi-card backup options, allowing users to secure redundancy at no extra cost. This affordability makes it highly accessible, especially for beginners or those needing a portable wallet for on-the-go use. Keystone costs between $129 and $229, depending on the model, with vendors often selling backups and accessories separately. While Keystone offers premium build quality and advanced features, its higher starting price may seem steep for everyday users. When it comes to pure accessibility and portability, Tangem provides more value for most people, especially considering its built-in backup solution.

Ideal User Profiles

Different users naturally prefer different wallets, highlighting the debate between Tangem and Keystone. Tangem works well for beginners, mobile-first users, frequent travelers, and crypto gifters. Its seedless, tap-to-sign design removes complexity, making it ideal for those who want security without the trouble of managing recovery words. On the other hand, Keystone is better suited for power users, multisig setups, and advanced situations where transparency and detailed control matter more than simplicity. Its seed phrase backup system and QR-based workflows attract those who want traditional recovery methods combined with visual security verification.
