FAQs

What is a hardware wallet?
A hardware wallet is a physical device that stores private keys and authorizes transactions offline, reducing exposure to malware and phishing compared to software wallets.

Do I need a hardware wallet if I use a centralized exchange?
If an exchange is hacked or freezes withdrawals, you can lose access. A hardware wallet lets you self-custody, so you control keys and recovery—many users keep long-term holdings in cold storage and only move funds when needed.

Is a Secure Element required?
Not required, but many devices use a CC EAL5+/EAL6+ Secure Element to resist physical extraction. Open-source firmware and verifiable builds also matter—evaluate the whole model, not just one spec. Ledger

What’s the difference between air-gapped QR and USB/Bluetooth?
QR/PSBT keeps signing data offline via camera or microSD. USB/Bluetooth devices can still be safe if the secret keys never leave the secure chip and screens verify data—choose the flow you’ll actually use correctly. coldcard.com+1

Can I use one wallet for multiple chains?
Yes—multi-chain devices (e.g., Ledger, Trezor, Keystone) support many networks. Bitcoin-focused devices (COLDCARD, Passport, Jade) prioritize BTC security and workflows.
