What Crypto Cold Wallets You Should Be Buying to Secure Your Assets? The Best Hardware Wallets
As we head into the final part of 2025, despite the ‘noise’, there is much to be bullish about in the market. As a whole, global cryptocurrency owners increased by 4% in the first half of 2025, up to 708 million, with that number only expected to go up.
Yet, studies suggest only 10% of people have their assets stored in cold wallets, leaving them much more vulnerable to crypto wallet attacks. If you’re an OG that has been in the market a long time and just want some extra blockchain wallet protection before your gains, or just learning the ropes, its vital to prioritise blockchain security.
Why It's Important to Secure Your Funds With The Best Hardware Wallets on the Market

By the end of June 2025, the amount of money stolen in crypto wallet attacks was $2.17 billion, with projections pushing that toward $4 billion by year-end. Personal wallet thefts represents 23.35% of all stolen fund activity, increasingly targeting individual users in 2025.

Trezor Safe 7
Open Hardware Security for Long Term HODLers
The Trezor Safe 7 has become the rock-solid investor target for those who want cold-wallet security that can evolve with the threat landscape. Set up with dual-chip design, the TROPIC01 and EAL6+ Secure Elements work alongside each other, helping add to physical attack resistance while maintaining transparency.

Ledger Nano S Plus
Budget, Entry-Level Choice
For most readers comparing cryptocurrency storage options on a budget, the Nano S Plus hits the sweet spot between cost and security fundamentals to safeguard from crypto wallet attacks.
It uses a modern ST33 Secure Element with EAL6+ certification to isolate private keys from any PCs or browsers that may have been compromised. Despite the lower price compared to other cold-wallet options, its storage is good with it being able to install up to 100 apps at once, keeping all major chains ready without the need to juggle between apps.
This device connects via USB-C, not Bluetooth, which is to the benefit of some buyers due to lack of Bluetooth being one less attack options for anyone trying to syphon your money. Pair with the Ledger Wallet to manage thousands of coins and tokens across different networks. The OLED display is small but functional when verifying amounts and addresses. Due to the lack of battery, the Ledger Nano S Plus is always ‘offline’ when unplugged – reassuring for long term storage.
In practice, you’ll get battle-tested BOLOS security and a huge asset ecosystem in a compact, affordable package—ideal as a primary signer for long-term holds, a travel backup, or secure experimental device for all of your DeFi needs.
Pros
- EAL6+ Secure Element
- 100 apps installed simultaneously
- No battery, no Bluetooth – simple wired operations good for those security conscious.
Cons
- Limited ‘on the go’ convenience without wireless/Bluetooth
- Small display lacking the quality-of-life extras that other Ledger products offer

SafePal S1
Affordable, Air-Gapped QR signing
If you want a cold wallet that keeps radios out of the conversation, the SafePal S1 is a smart, budget-friendly pick. Unlike hot wallets—or even some hardware wallets that rely on Bluetooth—S1 never connects over wireless. Instead, it uses an on-device camera to scan unsigned transactions as QR codes, signs them internally within its EAL6+ secure element, and then shows a new QR for your phone to scan and broadcast. Your private keys never touch a network interface, and malware on your phone or laptop can’t exfiltrate them because the signing process is contained entirely inside the device.
Daily use is straightforward. The 1.3″ colour screen and D-pad make it easy to review recipient addresses and amounts with human-readable clarity. Charging is handled via USB-C, and the 400 mAh battery provides plenty of life between sessions. Coverage is broad—200+ chains and 5,000+ coins—so you can consolidate multi-chain holdings into a single, consistent workflow. Through the companion app you’ll monitor your portfolio, access swaps and DeFi gateways, and still keep the S1 offline until it’s time to approve.
There are trade-offs. The QR flow adds a couple of steps compared with Bluetooth devices, and the UI/primo materials are more utilitarian than premium flagships. But the S1’s appeal is exactly that conservatism: fewer attack surfaces, predictable, repeatable security hygiene, and a friendly price. For readers who want Best Hardware Wallets protection with maximum separation from the internet, SafePal S1 is an excellent way to harden cryptocurrency storage without complicating your day-to-day.
Pros:
Air-gapped QR signing; no Bluetooth/Wi-Fi/NFC
EAL6+ secure element; wide chain/token support
Affordable, simple, and travel-friendly
Cons:
Extra scan steps vs. wireless models
UI/materials feel basic next to premium devices

Trezor Model One
Ultra-Affordable, Open Source Starter
Introducing now one of the original best hardware wallets. Retailed first for $1700 in 2014, you can now snatch the Trezor Model One for only $56 (£43 (as as Nov. 2025)). It’s inexpensive, transparent and reliable open-source approach enforces human-in-the-loop security with on-device confirmation (which is a long PIN) and optional passphrase. This creates hidden vaults separate from your primary accounts.
The Ergonomics are simple: a compact OLED and two buttons keep approvals deliberate without complexity. You run everything through Trezor Suite, which handles send/receive, swaps, staking, coin control, and privacy helpers like Tor.
However, with it being a budget device, there are trade offs: Micro-USB instead of USB-C, and some major networks aren’t supported natively (XRP, SOL, ADA, XMR). Therefore check your portfolio before buying. But, for BTC, ETH and many other ERC-20s, the Model One remains a battle tested entry point for easy to learn self-custody over your assets.
Pros:
- Open-source security, inc. PIN + Passphrase
- Low price
- Trezor Suite experience
Cons:
- No native support for XRP, SOL, ADA, XMR
- Micro-USB only
- Smaller display compared to other models

FAQs
-
1. Are hardware wallets (cold wallets) really safer than hot wallets?
Yes. Cold wallets keep your private keys offline inside a secure element or dedicated chip. Transactions are reviewed and approved on the device, which blocks most phishing-led crypto wallet attacks and malware-based key theft common to hot wallets. They’re not invincible—cold wallet vulnerabilities include poor recovery-phrase handling, supply-chain tampering, or physical access—but they materially cut everyday risk and improve blockchain wallet protection.
-
2. Which hardware wallet is best for mobile use?
For a phone-centric workflow, Ledger Nano X offers Bluetooth plus a built-in battery for on-the-go approvals. If you want wireless plus a big touch display and open-hardware posture, Trezor Safe 7 adds encrypted Bluetooth, Qi2 charging, and a 2.5" screen. Both deliver cold-storage isolation while keeping mobile convenience high.
-
3. What do EAL ratings (EAL5+/EAL6+) mean in hardware wallet security?
EAL (Evaluation Assurance Level) indicates the rigor of third-party security evaluation for a chip or system. EAL5+ and EAL6+ are high assurance levels; higher numbers generally reflect stronger resistance to physical attacks (fault injection, side-channel analysis). In practice, they help quantify hardware wallet security threats mitigation when comparing devices.
-
4. Do I still need a seed phrase with these wallets?
Usually yes: Ledger Nano X and Nano S Plus, plus Trezor Safe 7/Model One, use BIP39 12/20/24-word backups (Safe 7 also supports Multi-share Backup). The Safepal S1 is different -it's Air-gapped QR signing means no need to connect to Bluetooth or WiFi.
Cypherock X1 is different—it’s seedless, splitting your secret across four NFC cards, so no single item exposes the whole key.
-
5. What happens if my device is lost or damaged?
You can restore funds on a new device using your backup: BIP39 seed for Ledger, Trezor and the SafePal S1. For best cryptocurrency storage hygiene, keep multiple backups in separate locations, add a passphrase where supported, and periodically test a non-broadcast “dry-run” restore.
