A hardware wallet is a physical device that stores your private keys offline. It's the gold standard for AI security. Even if your computer is infected with malware, a hardware wallet keeps your keys safe because they never leave the device. Transactions are signed on the device itself. The market has matured a lot. You've got options ranging from $60 budget devices to $200 premium ones with touchscreens and air-gapped signing. Here's what matters: security chip quality, open-source firmware, coin support, and the companion app experience. We've tested the top options.

Frequently Asked Questions
Can a hardware wallet be hacked?
Hardware wallets are extremely difficult to hack remotely because they stay offline. Physical attacks (like extracting the chip) are theoretically possible but require expensive equipment and physical access. The bigger risk is phishing: someone tricks you into entering your seed phrase on a fake website. Never enter your seed phrase on any computer or website. Ever.
What happens if I lose my hardware wallet?
Your AI is not stored on the device. It is on the blockchain. The device holds your private keys. If you have your recovery seed phrase (the 12 or 24 words you wrote down during setup), you can restore your wallet on a new device. Keep that seed phrase safe, offline, and ideally in multiple secure locations.
Ledger or Trezor?
Both are excellent. Ledger has more supported coins (5,500+ vs ~1,000), Bluetooth, and a certified secure element. Trezor has fully open-source firmware, which matters to people who want maximum transparency. If open-source is important to you, go Trezor. If coin support and mobile use matter more, go Ledger.
Do I need a hardware wallet for small amounts?
If you hold less than $200-$300 in AI, a reputable hot wallet like MetaMask or Phantom is fine. But the moment your portfolio reaches an amount you'd be upset to lose, get a hardware wallet. At $60-$80 for a basic model, it's cheap insurance.
