Beginner's Guide To Hardware Wallets: How Tangem Wallet Works

Cryptocurrencies are a rapidly growing asset class, with a total market capitalization exceeding $2 trillion. And as crypto's mass adoption rate and popularity increase, so does the need for secure storage solutions.

Today's secure cryptocurrency storage options include a variety of solutions designed to protect user assets from theft. For example, hardware wallets are impervious to hacking attempts because they store private keys offline. Meanwhile, software (online) wallets use advanced encryption options that cater to a wide range of user needs but still have glaring disadvantages.

In this article, we discuss cryptocurrency's security challenges, hardware wallets, their advantages, and why the Tangem Wallet is the best crypto wallet for beginners.

Why secure wallets are important in the crypto landscape

One of the most difficult challenges in crypto investing is convincing investors that it is safe. Safety is critical because cryptocurrencies are bearer assets — self-custodial assets that can be traded with others without a centralized third party while being sufficiently liquid, fungible, and portable. There are additional challenges beginners might face, including:

  • The learning curve for cryptocurrency can be steep.   
  • Most investment advisors and brokerages do not yet support cryptocurrency investing, forcing beginners to validate investment opportunities and manage assets independently.   
  • The volatile nature of the space may cause FOMO (fear of missing out) in opportunistic investors, leading them to relax their guard regarding trusting platforms and "helpful hands."   
  • As more decentralized applications(dApps) emerge, opportunities for bad actors to manipulate these protocols or exploit security flaws to siphon or steal funds increase.   

According to a February 2023 report from Chainalysis, a crypto forensics firm that tracks illicit activity on blockchains, 2022 was the most successful year in crypto hacking history, with $3.8 billion stolen from cryptocurrency businesses. 

Eight security risks posed by custodial crypto wallets 

Although online wallets and crypto exchanges are convenient for managing digital assets, they pose significant security risks. From the threat of hacking and phishing attacks to regulatory compliance concerns, we outline the critical vulnerabilities beginners face with custodial wallets.

  1. Hacking attacks: Online platforms are vulnerable to cyberattacks and security breaches. If a wallet or exchange is compromised, users will lose funds stored in the exchange's hot wallet.   
  2. Phishing attacks: Crypto users may become victims of phishing scams in which they unknowingly provide their login credentials or private keys to fraudulent websites or emails masquerading as legitimate platforms.   
  3. Social engineering: Attackers may use social engineering techniques to trick users or employees into disclosing sensitive information such as passwords or private keys.   
  4. Lack of transparency: Some hot wallet providers do not provide sufficient clarity about their operations, raising concerns about their security and legitimacy.   
  5. Insider threats: Employees with insider access to the platform may abuse their privileges, potentially misappropriating "stored" customer funds.   
  6. Risks of regulatory and compliance violations: Online wallet providers and crypto exchanges fall under various regulations, and noncompliance may result in legal issues or shutdowns. In such a scenario, customers must move elsewhere or risk losing their funds.   
  7. Lack of control over private keys: Many online wallets and exchanges do not give users direct access to their private keys. Users face a total loss if the platform encounters a problem and abruptly shuts down.   
  8. Software vulnerabilities: Hackers can gain unauthorized access by exploiting bugs or vulnerabilities in the platform's software. Service attacks can temporarily disrupt online platforms' services, potentially causing users inconvenience or financial loss.

Exchanges are also vulnerable to market risks such as price manipulation, flash crashes, and other types of market volatility, which can affect their operations. Therefore, we strongly recommend using hardware wallets for storing your crypto assets. 

What are hardware wallets?

Hardware wallets include various devices, from a simple USB drive to intricately designed smart cards, outfitted with specialized security and accessibility features for storing cryptocurrency without internet access.    
This type of wallet protects the user's assets by generating and storing the wallet's private keys offline. This means that the keys are not exposed to hackers or malware. In addition to security, hardware wallets also offer several other benefits, such as:

  • Portability: Good hardware wallets are small and lightweight, so you can easily take them anywhere.   
  • Multi-currency support: Many hardware wallets support many cryptocurrencies so that you can store all your assets in one place.   
  • User-friendliness: The best hardware wallets must be easy to use, even for beginners.

Hardware wallets also have additional security features, including an access code or biometric authentication.

Some hardware wallets are unpopular due to their inconvenience, especially for day-to-day transactions, as they require you to plug them into a laptop or desktop computer before you can access your crypto.  

But what if you want a hardware wallet that combines the simplicity and ease of use of software wallets and the fortress-like security of hardware wallets? Let's take a look at Tangem Wallet.

Tangem: a leader in crypto hardware wallets

Tangem unveiled a next-generation self-custodial hardware wallet model in which the user's private key backup is not on a seed phrase. Instead, the key is securely generated and stored on smart cards that come in sets of two or three cards. When you activate a Tangem wallet, the wallet's chip generates the private key inside.   

If you lose one card, your assets remain safe because you have one or two other password-protected cards. You can make one card your primary crypto wallet, lock the second one in a box, and bury the third card in your backyard — it is as reliable and as tough as a Toyota Hilux truck.   

Tangem has produced over 850,000 cards since 2018 and maintains a perfect 0 hack record in over 141 countries. Customers also benefit from a 3-minute setup time and the highest level of security for digital assets that exist today.

What is the Tangem Wallet?

The Tangem Wallet is a self-custodial (you have complete control over your private keys) wallet built on a powerful, certified chip developed in collaboration with Samsung Semiconductors. The wallet supports over 6000 cryptocurrencies.   

With Tangem Wallet, you can store, buy, earn, transfer, and swap thousands of cryptocurrencies while enjoying access to DeFi, NFT, DeEX, and other services — all on one card with relative ease. Sounds too good to be true? Here's how it works

How Tangem Wallet works

There are two components at play in the Tangem Wallet. The first component is the hardware wallet device — a pack of two or three Tangem cards required to create one wallet. The second component is the Tangem mobile app, available on iOS and Android. Let's see how these two components work together. 

Tangem cards

Tangem cards come in a set of two or three. They are plastic cards with an inbuilt secure chip that functions as a microcomputer. When the card is manufactured, the chip generates its own key pair: the Kcardpriv private key and the Kcardpub public key.    

These keys are unique to each card and are not connected to the future user's wallet. They're only required so that the card can prove its authenticity and tell the app that Tangem manufactured it. The card's replacement warranty is 25 years, based on the minimum chip lifetime. 

The Tangem app

Because human beings cannot independently communicate and interact with microchips on a plastic card, there is a need for an interface or means of communication. That's precisely what the Tangem app is for. The Tangem app shows the functionalities of the Tangem wallet, including what assets are stored, asset management (send and receive crypto), and much more. So, how does a credit card-shaped wallet connect with your mobile phone? 

How Tangem cards and app interact

Both Tangem wallet components interact via Near-field communication (NFC). NFC is a wireless connectivity technology that allows devices to communicate when brought within a few centimeters of each other using magnetic field induction.    

NFC is based on inductive coupling between two antennas on NFC-enabled devices — your smartphone and the Tangem cards — communicating in one or both directions. 

Features of the Tangem Hardware Wallet

Tangem redefines the hardware wallet experience by providing unrivaled security, simplicity, and usability. Users can enjoy complete independence and autonomy while managing their assets with a single tap. Tangem Wallet lowers barriers for crypto newcomers while improving the custodial experience for advanced users.
