Those cards really look awesome and handy. Great job!
I can barely imagine carrying around a metallic coin so this solution fits perfectly for everyday payments.

I'm looking forward to get one 1st edition card; hopefully i'm fast enough.

These are not made for everyday payments they are a collectable btc storage medium as are coins.

Thank you everyone for your kind words.
We've been working a lot on this project these last months. It's awesome to see such a great reaction !
Physicals really are one of the best ways to spread crypto around.

Looking very cool can already buy-order?

Thank you !
Unfortunately, not yet but keep an eye open.
We will probably announce and open pre-orders for our very first edition later in April.

Will be looking forward to it....

Well they may be intended to be a storage only.

(Think out of the Box)
Who may stop me from exchanging such cards for goods & services?  

Edit: But, tbh, if i am able to get one of the first cards, i am probably going to keep that one anyway.

Will there be a public address list of all cards available?

That is a very interesting question.
We would like to try something different that what was done in the past.

The run will be limited, but customers will have the choice between "anon" and regular wallets.
Be careful, unless explicitly asked to be "anon" for some of the serial numbers you order, the cold wallets will be regular ones by default.

All regular card addresses will be published and the list will signed by my primary BTC address.
Anon cards addresses will not be published, not registered in the AuthKey database and not kept by the company.
The card will still be authenticable, but the tool will not contain the card address. That is all.

These anon cards will come with the following distinctive marking :



The total run will be limited, but we have no idea as to how many regular and anon ones will be made !

Needless to say: I like it!

Thank you everybody for your kind words.
This motivates us even further to come up with solutions to increase the security & authenticity of Coldkeys.
Hopefully someday, Coldkeys will be considered as a very safe and serious way to securily store crypto outside of an electronic device.

AuthKeys are a great way to prove the authenticity of Coldkeys.
However, if an AuthKey leaks, a malicious person could massively reproduce one card in particular, and those would be valid in the Authentication tool.
Also, it is a bit of a constraint put on people holding Coldkeys if we ask them to be careful with the AuthKey.
We want you to be able to freely take pictures and share them with everyone, so an extra security step was indeed necessary.

Here is our latest improvement, let me introduce the UV AuthKey :






Other than that, everything is going by the schedule.
The shipping of the Genesis Edition Coldkeys is planned to start in approximatively a month.
I will get in touch at beginning of June with everyone who made a reservation, so we can confirm if you want Regular or Anon cards.

Stay tuned ! A lot of things are about to happen.
Thank you all very much for all your support !! Coldkeys would have never seen the light of day without the community as a source of inspiration !

[krogothmanhattan]

Great idea on security Yogg! Waiting with eagerness for these cards!

Yogg, my ColdKey arrived today!! Cheers! Very impressed with it all, both the card and the packaging. ColdKey is a true innovation that is far bigger than just a collectible, but the genesis edition serves as an homage to Collectibles with its 0 BTC face value. Very excited to see more of your developments (loaded/small denominations/collaborations/etc)

To anyone who hasn’t picked up one of these yet, WHAT ARE YOU DOING? I highly recommend getting one while you still have the chance.

Wow ! Thanks for the awesome feedback tothemoonsands !

Yes, Coldkeys are indeed intended for several purposes.
There will some more cool things to happen soon.

The Genesis Edition Coldkey is our first publicly sold release.

We wanted to do something to commemorate Coldkey's ignition, and this is the purpose of that serie.
In fact, the 0 BTC denomination was inspired by Casascius with the "Zero BTC Gold Bearer Bars".
About 8 years after these were sold, at the very spawn of Bitcoin, these are super desired and rare.

[StackItUp]

Would like to buy at least 1 coldkey. Please dm me with BTC address of yours and shipping cost to EU. Cheers
