Fade Resistant

Hack Resistant

Physical Theft Proof

With the Cold Code Kit you only physically store your random word-list: making theft of your real word-list impossible.

Additionally the Cold Code Kit provides you with multiple physical copies, so if someone steals one of your dummy word-lists, you will still be able to recover your real word-list with the other.

Hack Resistant

Hacking your real word-list is impossible when only your Cold Code is stored digitally.

A hacker would also need to steal your physical dummy word-list to recover your real word-list.

This combination of physical and digital decentralized storage is what makes Cold Code the most secure method of word-list storage created to date.

Fire resistant

Your stainless steel "dummy" word-list is made of thick, 18 gauge, grade 304 stainless steel that can resist temperatures above 1500 degrees F (815 C) - well above the average house fire temperature of 1,100 degrees F (594 C).

Corrosion & fade resistant

Your stainless steel "dummy" word-list is permanently marked using a powerful fiber laser to deely anneal the surface of the stainless steel.

This process is industry standard in aeronautical and medical fields because of its high contrast and permanence - guaranteeing your wordlist will last more than a lifetime.

100% Peace of Mind

The Cold Code Kit allows you to create your own Cold Code, so that you never have to trust anyone with your real word-list potentially jeopardizing your private crypto keys.

Other companies offer similar services that are based on your trust in their security and faith that they will not save or mishandle your private keys.

We believe this is against the very nature of crypto! You should never have to entrust any company with your keys - and at Cold Code we provide you with the tools to control your own private keys.

Affordable

Simple is best. 

In the high-tech world, sometimes you need a low-tech solution; the Cold Code method is so elegantly simple that we're able to provide you with top-notch security at a fraction of the price.

With your Cold Code Kit you can store an unlimited number of real word-lists using the same physical "dummy" word-list.

There's no need to purchase multiple physical "dummy" word-lists unless desired. We pride ourselves on being able to offer the most value in this exciting and growing industry.
