A plain-English guide to the three leading hardware wallets โ Tangem, Ledger and Trezor. We cover what they are, how they work, how much they cost, and crucially โ every known security incident you need to be aware of.
Prices and security data correct as of April 2026A hardware wallet is a physical device that stores the private keys to your cryptocurrency completely offline โ away from the internet, away from hackers, and away from exchange collapses.
When you leave your crypto on an exchange (like Coinbase or Kraken), the exchange holds the private keys โ not you. If the exchange is hacked, goes bust, or freezes withdrawals, your money could be gone. A hardware wallet means only you control your crypto.
The downside is that you are entirely responsible. If you lose the device and your backup, your crypto is gone forever. There is no "forgot password" and no customer support that can recover your funds.
We've researched each wallet thoroughly, including every known security incident. Here's what you need to know.
Swiss-made ยท Founded 2017 ยท Card & Ring form factor
Tangem takes a completely different approach to hardware wallets. Instead of a USB stick with a screen, it's a credit-card-sized NFC card (or a wearable ring) that you tap against your phone to sign transactions. There's no battery, no cables, and โ uniquely โ no seed phrase required by default. Private keys are generated on the chip itself and never leave it.

French-made ยท Founded 2014 ยท USB stick form factor
Ledger is the world's most popular hardware wallet manufacturer, with tens of millions of devices sold. The Nano X is the flagship model with Bluetooth connectivity and a larger screen, while the Nano S Plus is the more affordable option with USB-C only. Both use a certified secure element chip to store your private keys offline and have a small screen to verify transactions on the device itself.

Czech-made ยท Founded 2013 ยท USB stick form factor
Trezor, made by Czech company SatoshiLabs, was the world's first hardware wallet. The current flagship lineup is the Safe series โ the Safe 3 (with a secure element chip) and the Safe 5 (with a touchscreen). Trezor's biggest differentiator is that both its firmware and hardware designs are fully open source, meaning anyone can inspect the code for vulnerabilities. This is considered by many security experts to be the gold standard of transparency.

The best wallet depends entirely on how you plan to use it. Here's a plain-English verdict for each type of user.
If you're new to crypto and want something that just works without a steep learning curve, Tangem is the most approachable option. No seed phrase to worry about, no cables, and it fits in your wallet. Buy the 3-card set and store one card somewhere separate as a backup.
If you hold a significant amount of crypto or actively use DeFi applications, the Nano X's broad ecosystem and Bluetooth connectivity make it the most versatile choice. Be aware of the data breach history and use a non-residential delivery address when ordering.
If you prioritise transparency and open source code above all else, Trezor is the only fully open source hardware wallet in this list. The Safe 3 offers excellent security at an affordable price. Use Shamir Backup to split your seed phrase across multiple secure locations.
