Why Cryptosteel Capsule?

With traditional banking you are the most important person.  In contrast, cryptocurrencies don’t care about the person, but rather the private key associated.

Anyone who has access to your private key can therefor spend your funds.  Likewise to spend your funds you must have access to your private key.  Your private key is backed up by a recovery seed phrase.  It is for this reason you must keep your recovery seed phrase safe.

Cryptosteel is Hacker-proof and designed to survive extreme conditions and unimaginable disasters and even current and next-gen methods of surveillance. 

How Cryptosteel Capsule Works?

Cryptosteel Capsule is a pocket-sized portable steel vault designed to securely store important data of your choice with no need for specialised tools or third-party involvement.

Each Capsule comes with a kit of deeply stamped stainless steel tiles to provide maximum longevity and resistant to physical damage, including fire, flooding, corrosive conditions, electric shock and impact from accidents.

Recovery Phrases, Passphrase, Passwords and other Random Codes and Secrets can all be manually assembled from the supplied set of semi random characters. Once a desired sequence is locked into a Capsule, it gains the status of offline lifetime permanence.
