About Crypto Key Stack
Crypto Key Stack is a stainless steel, offline backup device for your most sensitive information including mnemonic phrases, private wallet keys, and passwords. The set contains the stainless steel plates of your choosing and also always contains the engraver, to allow you to write your information.
Crypto Key Stack LLC was co-founded by Chris Gonyo and NFL veteran Israel Idonije in an effort to reduce the billions of dollars lost due to improper private key storage.
Chris and Israel realize that software-based hardware wallets are excellent for cybersecurity, but become vulnerable in the event of a physical disaster. So they designed Crypto Key Stack to help preserve access to your assets in the event of a hardware failure and physical disaster.
Crypto Key Stack was created out of a need for an affordable, high-quality stainless steel backup device that allowed users to store multiple cryptographic keys permanently.
