Cryptocurrency theft topped $2 billion in 2025—it's time to rethink how assets are stored.

Key Takeaways

Multi-billion-dollar crypto thefts highlight the critical need for reliable offline storage of digital assets. Hot wallets and exchange platforms face constant threats—their continuous internet connection makes them prime targets for phishing attacks, regulatory freezes, and hacking groups.

Innovative solutions like Kraster Wallet offer a straightforward alternative to bulky, expensive traditional hardware devices. With its card-based format and 24/7 technical support, Kraster combines the security of a cold wallet with the convenience of mobile asset management.

Why Secure Storage Matters Now More Than Ever

Recently, cybercriminals stole over $2.17 billion from various crypto platforms—exceeding last year’s total. According to analytics firm Elliptic, North Korean hacker groups alone stole more than $2 billion during this period.

Despite clear risks and numerous security incidents, many users continue to keep their assets on exchange platforms or in mobile wallets that are always online. This approach introduces multiple vulnerabilities, from phishing attacks to compromised storage servers.

Cold wallets remain the most reliable method for crypto asset storage. The main barrier to widespread adoption is the relatively high device cost and complex initial setup, which leads most users to delay switching to secure storage solutions.

Weaknesses of Traditional Hardware Wallets

Hardware wallets from brands like Trezor and Ledger offer robust private key protection, but their setup process can be daunting for newcomers to crypto. Users must initialize the device, complete multiple security steps, and connect a dedicated desktop app for full functionality.

Accessing decentralized finance applications (DeFi) usually requires third-party software wallets, which adds extra steps and introduces potential points of vulnerability. Additionally, the physical size of traditional devices is not always practical for daily use or transport.

Kraster Wallet: Quick Overview

Kraster Wallet delivers an innovative solution for secure crypto storage:

• Design & Form Factor: hardware wallet sized like a standard bank card, managed through an intuitive mobile app
• Storage Security: private keys are stored directly on the physical card, fully offline and protected from network-based attacks
• Backup System: available in sets of 2 or 3 identical cards with the same keys; offers seed phrase creation for emergency recovery
• Blockchain Support: compatible with 100+ blockchains, including Bitcoin, Ethereum, Solana, Polygon, and TON
• Affordable Pricing: $45 for a basic two-card set and $60 for a three-card bundle

What Makes Kraster Wallet Stand Out

Kraster features a slim plastic card, identical in size to a standard bank card, offering maximum convenience for storage in a wallet or cardholder. Inside, a secure chip holds the private key, fully isolated from the internet and all network connections.

Every transaction requires the physical card to be near your smartphone. Even if an attacker gains full access to your mobile device, transferring funds without the card is technically impossible. This provides an additional layer of protection against remote attacks.

Initial setup takes just a few minutes and requires no special technical skills. The mobile app serves as a user-friendly control center—send and receive crypto, swap tokens, sign transactions, add labels to transfers, and track balances across 100+ blockchains.

The cards are designed to last about 25 years with proper use, and accessible pricing makes Kraster more attractive than classic hardware wallets for a wide range of users.

Kraster Wallet Security: Multi-Layer Protection

Private keys never leave the physical card and are never transmitted via the mobile app or internet. Every asset transaction requires physical confirmation with the card plus PIN or biometric authentication on your smartphone. Even if an attacker accesses an unlocked phone, funds remain inaccessible without the card.

Private keys are not stored on Kraster servers or sent over any network. The manufacturer has no technical access to user private data, fully adhering to decentralization principles.

Kraster’s Core Security Features

• Private keys always remain offline, secured on the chip
• Every transaction requires the physical card and PIN or biometric confirmation
• Private data never travels over networks or sits on remote servers
• Zero-trust architecture minimizes risks from various attack types
• Backup cards enable quick recovery if one card is lost
• Optional seed phrase adds an extra recovery method

User-Friendly Interface

Kraster Wallet proves that secure crypto storage can be simple and accessible to everyday users. The mobile app’s intuitive graphical interface resembles familiar software wallets, so even beginners can easily navigate its features without a technical background.

Users can view all connected wallet balances, add text labels to transactions for tracking, review fee amounts before sending, and manage multiple assets right from the main screen. All critical actions require confirmation with the physical card, preventing unauthorized activity.

24/7 Technical Support

Kraster takes a unique approach to client service by offering 24/7 technical support with live, qualified specialists. The team assists with setup, detailed security configurations, and advanced wallet functions—no bots or long wait times involved.

This support is especially valuable for new users who may have questions during their first cold wallet experience. Professional assistance significantly lowers the barrier to adopting secure storage solutions.

Looking to the Future: A New Era of Self-Custody

The Kraster team is developing next-generation tech—an implantable chip wallet that can be securely placed under the skin. The project aims to unite digital cryptographic security with the physical reliability of biometric storage, eliminating the risk of losing or having private keys stolen.

This innovation could transform digital asset storage, making authentication both seamless and absolutely secure. The user would be inseparable from their crypto keys.

Is Kraster Wallet Right for You?

Choosing the right crypto storage solution depends on your personal priorities and needs. If you want maximum asset security without complex setup or high costs, Kraster offers a balanced, practical option.

The product delivers robust hardware protection for private keys, convenient mobile asset management, and full financial autonomy—no need for centralized exchanges or cloud storage. Kraster Wallet appeals to both newcomers and experienced crypto holders alike.

Cold wallets are the most secure (private keys stored fully offline). Hot wallets are convenient but vulnerable. The best approach is a hybrid strategy: use cold storage for primary assets and a hot wallet for trading.

How can individual investors protect their crypto assets from theft?

Store main funds in cold wallets, enable two-factor authentication, change passwords regularly, never share private keys, and verify addresses before sending funds.

Can stolen cryptocurrency be recovered? What recovery measures are there?

Recovering stolen crypto is difficult, but options include freezing assets, legal action, and seeking expert help. Success depends on the situation and cooperation with law enforcement.

Hardware wallets, paper wallets, and multisig wallets: what are their pros and cons?

Hardware wallets offer strong security with independent key storage but are expensive. Paper wallets are low-cost but at risk of loss. Multisig wallets require multiple parties to approve transactions for added protection but are more complex to use.

What are the standards for evaluating exchange security? How do you choose a reliable exchange?

Evaluate exchanges by their licenses, security record, user protections, and trading volumes. Choose regulated platforms with positive reviews and two-factor authentication to keep assets safe.

How should private keys, mnemonic phrases, and passwords be stored securely?

Keep private keys and mnemonic phrases offline—in a safe or hardware wallet. Don’t share them, use two-factor authentication, and regularly verify backups for recovery. Never store them in the cloud or online.
