Hardware wallets are the gold standard for securing cryptocurrency. We tested and compared the top cold storage devices — Ledger, Trezor, and BitBox — across security, ease of use, and asset support to help you choose the right one for your needs.
If you own more than a few dollars in crypto, you've probably heard the mantra: not your keys, not your coins. Keeping your private keys on a phone, laptop, or exchange is a gamble. Hardware wallets — dedicated devices that store your keys offline — are the safest way to hold crypto long-term.
Software wallets (like MetaMask or Exodus) are convenient for daily use, but your keys live on an internet-connected device. A hardware wallet keeps your seed phrase and private keys completely offline, signing transactions only when you physically confirm them. That's cold storage you can actually use.
Here are the best hardware wallets for crypto right now, broken down by who they're for.
| Product | Secure Element | Open Source | Connectivity | Asset Support | Best For |
|---|---|---|---|---|---|
| Ledger Nano X | ✅ Yes (ST33K1M5) | Partial | USB + Bluetooth | 5,500+ coins & tokens, staking via Ledger Live | Power users who want Bluetooth & DeFi |
| Ledger Nano S Plus | ✅ Yes (ST33K1M5) | Partial | USB-C only | 5,500+ coins & tokens | Beginners on a budget |
| Trezor Model One | ❌ No (standard MCU) | ✅ Full | USB only | 1,800+ coins & tokens | Privacy advocates, open-source purists |
| BitBox02 (Bitcoin-only) | ✅ Yes (ATECC608A) | ✅ Full | USB-C only | Bitcoin-only (multi-edition available) | Bitcoin maximalists, build-quality seekers |
Why it won: The Ledger Nano X is the most feature-rich hardware wallet on the market. It connects via Bluetooth to the Ledger Live mobile app, so you can manage your portfolio and sign transactions on the go without plugging anything in. It supports over 5,500 cryptocurrencies and lets you stake assets like Ethereum, Solana, and Tezos directly from the device.
The Secure Element chip (ST33K1M5) is the same grade used in passports and payment cards, giving it a hardware-level security advantage over wallets that rely on general-purpose microcontrollers.2 Ledger Live also integrates with 1,000+ DeFi protocols, making it the best choice if you're actively using your crypto.
Trade-off: Ledger's firmware is not fully open source — only parts of it are. For some in the crypto community, that's a dealbreaker.
Bottom line: If you want Bluetooth convenience, broad asset support, and staking in one device, the Nano X is the pick.
Why it won: The Nano S Plus strips out Bluetooth and a few bells and whistles to deliver the same core security at a lower price. It still supports the full Ledger Live ecosystem — 5,500+ coins, staking, and DeFi access — via a wired USB-C connection.
For someone buying their first hardware wallet, this is the sweet spot. You get the same Secure Element chip as the Nano X, the same recovery options, and the same software, just without the wireless convenience.2 It's also compact enough to stash in a safe or drawer.
Trade-off: No Bluetooth means you need a computer or an OTG adapter to use it with a phone. The screen is smaller, too.
Bottom line: The best entry-level hardware wallet for anyone serious about crypto security.
Why it won: Trezor was the first hardware wallet ever made, and it remains the champion of open-source transparency.1 Every line of code — firmware, bootloader, even the web interface — is publicly auditable. That matters if you don't want to trust a company's closed-source claims about security.
The Model One is simple, reliable, and supports over 1,800 coins. It's also one of the most affordable hardware wallets available. The community loves it for its no-compromise approach to transparency.1
Trade-off: No Secure Element chip — it uses a general-purpose microcontroller, which is theoretically more vulnerable to physical attacks (though no such attack has been demonstrated in practice). No Bluetooth, and the screen is monochrome.
Bottom line: If open-source transparency is your top priority, the Trezor Model One is the honest choice.
Why it won: The BitBox02 from Swiss company Shift Crypto is a work of engineering. It combines a Secure Element chip (ATECC608A) with fully open-source firmware — a rare combination that gives you both hardware-level protection and code transparency.
The Bitcoin-only edition is exactly that: no altcoins, no DeFi, no staking. It's a focused, minimalist device for people who want the absolute safest way to hold Bitcoin. The build quality is exceptional, with a tactile microSD card slot for backup and a compact form factor that feels premium.3
Trade-off: Bitcoin-only (a multi-edition is available but less focused). Smaller community and ecosystem compared to Ledger and Trezor.
Bottom line: The best-built hardware wallet for Bitcoin maximalists who want open source and a Secure Element.
Secure Element vs. Open Source: A Secure Element chip protects against physical tampering and side-channel attacks. Ledger and BitBox use them; Trezor doesn't. But Trezor's fully open-source firmware means anyone can verify its security. There's a philosophical trade-off here.
Connectivity: Bluetooth (Ledger Nano X) is convenient for mobile use. USB-only devices are simpler and have a smaller attack surface. Pick based on whether you'll manage your wallet from a phone or a computer.
Asset Support: Ledger supports the most coins and tokens (5,500+). Trezor covers the major ones (1,800+). BitBox's Bitcoin-only edition is intentionally limited. If you hold a wide portfolio, go Ledger.
