- Test Recovery: Before sending large amounts, test the recovery process on a secondary device.
- Consider Multisig: For holdings over $100k, a multi-signature setup provides additional security layers.

Frequently Asked Questions
What is cold storage for cryptocurrency?
Cold storage means keeping your cryptocurrency private keys completely offline, disconnected from the internet. Hardware wallets are the most common form. This eliminates the risk of remote hacking, malware, and phishing attacks that can compromise online (hot) wallets.
How do I set up a multi-sig cold storage?
Multi-signature (multisig) requires multiple private keys to authorize transactions. For example, a 2-of-3 multisig requires 2 out of 3 hardware wallets to sign. Tools like Sparrow Wallet, Electrum, or Casa make multisig setup accessible. Store each key in a different physical location for maximum security.
What happens if my hardware wallet breaks?
Your crypto is safe as long as you have your recovery seed phrase (12 or 24 words). You can restore your wallet on a new device using this seed. Store your seed phrase on durable material (steel plates are recommended) in a secure location separate from the device.
