• Tangem’s card-based design is portable, but its lack of a screen means transactions can’t be verified—risky for large holdings.

In the crypto world, securing assets has always been the top concern for investors.
Whether it’s Bitcoin, Ethereum, or other digital assets, once a private key is exposed online, it may face threats from hackers, phishing contracts, and malware.
Cold wallets (hardware wallets) provide the most effective protection. With offline private key storage, hardware-level secure chips, and multi-factor verification mechanisms, cold wallets help investors minimize risks and truly keep ownership of their assets.
In this review, we compare today’s leading cold wallets across three dimensions — security, user experience, and long-term reliability — to help you find the best choice.
How to Choose the Right Cold Wallet?
There are more and more cold wallets on the market, with wide differences in functionality. For most users, the following criteria are key:
- Security: Does it use an EAL 6+ secure chip? Does it include physical confirmation or multi-factor verification?
- Transparency: Is the firmware open source? Has it passed third-party verification such as WalletScrutiny?
- User Experience: Are transaction details clearly displayed (preventing blind signing)? Does it support Bluetooth, NFC, or QR code signing?
- Multi-Chain Compatibility: Does it support BTC, ETH, and other L2 or cross-chain ecosystems? Is it compatible with Web2 login or multisig?
- Trust & Backing: Does it have reputable institutional investment or community support? Has it passed security audits?
Once these standards are clear, comparing different products becomes much more straightforward.

Reviews and Analysis of Major Cold Wallets
- OneKey Pro
Equipped with four EAL6+ secure chips, color touchscreen, fingerprint, and wireless charging. Paired with SignGuard, it prevents blind signing and supports Turbo Mode — ideal for users who want both security and usability. - OneKey Classic 1S
Affordable, fully open source, and built with an EAL6+ secure chip. A great choice for long-term BTC/ETH cold storage. - Ledger Stax
Rich in features with a curved E-Ink screen. However, closed-source firmware and reliance on Ledger Live lower transparency, and the price is high. - Trezor Safe 5
Open source with strong community recognition. Reliable and simple, but weaker in phishing defense and transaction parsing. - Ellipal Titan 2.0
Fully air-gapped with QR-based interaction. Eliminates online risks but suffers from closed-source limitations. - BitBox 02
Swiss-made, compact, supports BTC/ETH. Despite its limited screen, it remains stable and reliable for long-term storage. - Tangem
Card-based design, convenient for carrying, but the lack of a screen means transaction details are not displayed — not recommended for large amounts.
Cold Wallet Trends and Market Outlook
Between 2024–2025, cold wallet adoption has evolved significantly:
- From Whales to Everyday Users
Once seen as “whale-only” devices, cold wallets are now increasingly adopted by everyday users as phishing and approval attacks rise. - Identity + Security Convergence
Cold wallets are evolving beyond storage tools, becoming “digital identity keys” for the multi-chain world. For example, FIDO login enables wallets to serve as a unified Web2 / Web3 authentication method. - Enhanced Security Features
From simple offline signing to real-time risk parsing (SignGuard) and Turbo Mode, modern hardware wallets now act as proactive security assistants, not just passive storage.
Why OneKey Is the Most Secure and Recommended Wallet in 2025
SignGuard: What You See Is What You Sign, With Real-Time Risk Alerts
Traditional hardware wallets protect private keys, but many users still lose funds to blind signing (approving unreadable transactions).
OneKey’s SignGuard solves this issue. By combining App + hardware verification, it parses transactions fully and integrates GoPlus, Blockaid, and ScamSniffer to detect malicious contracts, fake tokens, and phishing in real time.
- App side: Displays human-readable transaction details such as transfer method, approval amount, target address, and contract name instead of raw hashes.
- Hardware side: Shows transaction summaries on the device, ensuring safe confirmation even on compromised computers.
- User experience: Every signature requires hardware confirmation — truly “what you see is what you sign.”
Unlike wallets with partial previews on limited chains, SignGuard already supports Ethereum, BNB, Tron, Polygon, Arbitrum, Optimism, Base, Scroll and more.
It is not an optional feature — it is the core security framework of OneKey.
Conclusion
A cold wallet is essential for securing crypto assets.
Among the many options in 2025, OneKey Classic 1S and OneKey Pro stand out with their strong secure chips, open-source transparency, and exclusive risk-parsing capabilities, making them the most trustworthy choices.
