Cryptocurrencies represent a rapidly expanding asset class, with total market capitalization surpassing $3 trillion. As mass adoption and popularity grow, so does the need for secure storage solutions.
Today’s cryptocurrency storage options include various methods designed to protect user assets from theft. Hardware wallets, for instance, store private keys offline, making them immune to remote hacking attempts. Software wallets, while convenient and often equipped with advanced encryption, still present notable security disadvantages.
This guide explores the security challenges in cryptocurrency, examines the pros and cons of hardware wallets, and highlights why Tangem stands out as a leading solution.
The Importance of Hardware Wallets in Crypto
One of the biggest hurdles in crypto investing is assuring users of safety. Cryptocurrencies are bearer assets—self-custodial, liquid, fungible, and portable—but this also places responsibility squarely on the user. Beginners, in particular, face challenges such as:
- A steep learning curve for understanding blockchain and crypto management.
- Limited support from traditional investment advisors or brokerages, requiring self-education and independent asset management.
- Market volatility that can lead to impulsive decisions, including trusting unverified platforms.
- The rise of decentralized applications (dApps), which can introduce security risks if not properly audited.
In the first half of 2024 alone, cryptocurrency thefts reached approximately $1.38 billion—nearly double the amount stolen during the same period in 2023. Prominent heists, including a $243 million attack involving phishing and social engineering, underscore the critical need for secure storage.
Eight Security Risks of Hot Wallets
Online (hot) wallets and crypto exchanges offer convenience but come with significant vulnerabilities:
- Hacking Attacks: Centralized platforms are prime targets for cyberattacks.
- Phishing Scams: Users may inadvertently share credentials via fake websites or emails.
- Social Engineering: Tricks and manipulation can lead to unauthorized disclosure of private keys.
- Lack of Transparency: Some providers do not fully disclose security practices or operational details.
- Insider Threats: Employees with system access could potentially misappropriate funds.
- Regulatory Risks: Legal non-compliance could result in service shutdowns and fund freezes.
- No Private Key Control: Users often don’t hold their private keys, risking total loss if the platform fails.
- Software Flaws: Bugs or vulnerabilities may be exploited to gain unauthorized access.
For these reasons, we strongly recommend using physical devices for storing cryptocurrency assets.
What Are Hardware Wallets?
Hardware wallets are physical devices—ranging from USB sticks to smart cards and wearable rings—designed to manage cryptocurrencies and sign transactions offline. They protect assets by generating and storing private keys offline, away from internet-based threats.
Key benefits include:
- Portability: Compact and easy to carry.
- Multi-Currency Support: Many devices support thousands of cryptocurrencies.
- Ease of Use: Well-designed wallets are intuitive, even for beginners.
Additional security features often include PIN codes, biometric authentication, and tamper-resistant hardware. However, some earlier models required cables or computer connections, making them less convenient for daily use.
Tangem offers a modern alternative that combines the security of hardware wallets with the simplicity of software wallets.
Introducing Tangem: A Leader in Hardware Wallets
Tangem offers a next-generation self-custodial model. Instead of relying on seed phrases, private keys are securely generated and stored directly on the device—available as cards or a ring. Each Tangem Wallet chip generates its own private key during activation.
If you lose one card, your assets remain secure thanks to backup cards, each protected by an access code. You can use one card daily, store another in a safe, and even keep a third off-site for maximum redundancy.
Since 2018, Tangem has produced over 2 million devices with a perfect zero-hack record. Users enjoy a three-minute setup and industry-leading security.
What Is the Tangem Wallet?
The Tangem Wallet is a self-custodial hardware wallet built on a certified secure chip developed with Samsung Semiconductors. It supports more than 13,000 cryptocurrencies and allows users to store, buy, earn, transfer, and swap assets—all while accessing dApps, NFTs, and decentralized exchanges (DEXs) from a single device.
How the Tangem Wallet Works
The system consists of two parts: the physical device (cards or ring) and the Tangem mobile app for iOS and Android.
Tangem Cards
Tangem cards are sold in sets of two or three. Each card contains a secure chip that acts as a microcomputer. During manufacturing, the chip generates a unique key pair used to verify authenticity—ensuring that the card is genuine and produced by Tangem.
Tangem Ring
The Tangem Ring is a wearable hardware wallet made from durable Zirconia Ceramic. It offers the same security as the cards but in a form designed for daily wear.
The Tangem App
The Tangem app serves as the communication interface between the user and the physical device. Since humans can’t interact directly with microchips, the app translates user actions into commands the hardware can execute.
How the Device and App Interact
Communication occurs via Near-Field Communication (NFC)—a wireless technology that enables contactless data exchange over short distances. By tapping the Tangem device to an NFC-enabled smartphone, the two establish a secure connection for signing transactions and managing assets.
