Frequently Asked Questions

I would like to buy a hardware wallet. Do I need a seed phrase recovery solution like the Cryptosteel Capsule or Cassette?

Yes, a recovery solution is essential for safeguarding your cryptocurrency assets. It ensures that you can restore access to your wallet if your primary device is lost, stolen, or damaged. By securely storing your seed phrase or private keys offline using a robust solution like Cryptosteel, you protect your holdings from online threats and physical damage, ensuring long-term access and security for your digital funds.

Why store my seed phrase offline?

Storing your seed phrase offline protects it from online threats such as hacking, malware, and phishing attacks. Offline storage ensures that your seed phrase remains secure even if your computer or mobile device is compromised.

What is the difference between the seed phrase and private key?

Seed Phrase: A seed phrase, also known as a recovery phrase, is a series of words generated by your cryptocurrency wallet. It serves as a master key to recover your entire wallet, including all private keys and funds, if your device is lost or damaged.

Private Key: A private key is a cryptographic code that allows you to access and manage a specific cryptocurrency address. Each private key corresponds to a single address, and it must be kept secure to prevent unauthorized access to your funds.

While a seed phrase can restore an entire wallet, a private key provides access to individual addresses within that wallet.

What are the Cryptosteel devices made of?

The Capsule’s parts are made of 100 percent AISI 304 and 303 grade stainless steel while the Cassette is made of 100 percent AISI 304 grade stainless steel to withstand just about anything. In fact, one of our biggest challenges was to design and produce a construction made entirely from these top-grade materials, with no parts whatsoever made of anything else. After all, a solution is only as strong as its weakest element, so we made sure that Cryptosteel has no weak spots.

Do you have a return policy?

Absolutely. It’s our Cryptosteel Lifetime Satisfaction Guarantee, and we mean every word of it.
