Hi... just want to ask how the keys are put on the steel wallet. Is it printed on the surface of the metal card? Or is it actually etched out on the metal, making it permanent even if the black print fades, similar to an embossed credit card. Even if a credit card's color fades, the numbers are embossed and permanently raised.

The nice thing about your wallet is that, being metal, it is fire and waterproof and will survive termites and other pests which might find paper wallets delicious. Imagine finding half of your private key with, say, 100 BTC chewed off!

No printing! I engrave information with laser. I burn metal deeply (~0.1 mm - beleive me, it is deep) to form everything you see on the sruface. No chance to erase information on Coin Armor except you'll try to grind it Wink

Scrappy, first of all - thanks.
You can pledge 3*40=120$ for 9 titanium coin armors and leave me a private message on Kickstarter. and I'll make a note to myself.

People don't need to beleive me. Just read this article https://bitcoinpaperwallet.com/bip38-password-encrypted-wallets/

Thanks for support!

Why wouldn't I just take some sort of stamp and stamp a piece of metal with my private key? Wouldn't this achieve the same results? Also, isn't this just another version of a steel wallet, which has already been done before? What's the difference with yours?

My proposition is more convinient,cheaper and better made Wink That's all.

Guys, why you neeed to hide BIP38 key? Or even trust me to destroy those keys?
You'll give me ONLY encrypted key and only you will know pass-phrase.
I propose to all backer on Kickstarter to use this site: https://walletgenerator.net and generate there BIP38 protected keys. And for sure don't tell me that pass phrase.

The only thing you need to trust me is that I'll make engravings on metal cards Wink But that will be a really bad idea to bury a successful kickstarter account for extra several hundreds dollars.

Interesting concept honestly, but my question comes down to the passphrase. How would they know How would the private key be encoded with a second passphrase and only they (the customer) would know it?

Hi. We recommend to use this service https://walletgenerator.net to generate Crypto address and pass-phrase protected private key. Please try to generate paper wallet and hit checkbox "BIP38 Encrypt?". After that you need to enter passphrase that will be needed to encode your key. And nobody except you will know that passphrase.

Thanks Olaf! Really appreciate that.

So how is your project better than what cryptosteel, bitkee , cryobit are doing?

You're just basically engraving letters and numbers on a metal sheet.
The rest is just fancy words.
I can do that in the nearby home depot for 5 euros.

Yeah I would agree in this. The project is good and I would like to carry a fancy card with me, but that's just it. It's just a fancy card with my private keys. If I'm never going to use to I would rather store them at a safe place than my pocket.

That's it - metal card with engraved letters. What were you expecting for 15$ + worldwide shipping?
Just a a reliable version of paper note.
10  Economy / Goods / Re: Coin Armor - steel cryptocurrency wallet on: January 05, 2018, 09:53:54 PM
Yep. People are shouting Scam! Scam! all time on forums. Need to explain about pass-phrase protection over and over again Wink
11  Bitcoin / Bitcoin Discussion / Re: Coin Armor - cold wallet in a form of metal credit card for long term storage on: January 05, 2018, 03:33:25 PM
Thanks. Need somehow to attract attention to this project Wink
12  Bitcoin / Bitcoin Discussion / Re: Coin Armor - cold wallet in a form of metal credit card for long term storage on: January 05, 2018, 11:23:28 AM
Makes sense, but where do you want to store the private key or the passwords? Donīt get me wrong, but to store both information, Address and keys, is very unsecure. How do you make it safe?

Private key is pass-phrase encrypted. I don't know it and so I don't know your real key. Where to store pass-phrase? That's  your decision.

Thanks for your opinion!
Anyway, it should be compact from my point of view. And credit card has enough space to store QR code and key in a text form.
If you do like the idea please spread a word about it. Post in social networks etc.
That project is not about profit (15$ for cutting, polishing, engraving, shipping and my time Wink ) it's about attracting newcomers into a cryptoworld, that are afraid of hackers, fraud, stock exchanges etc. Just a cheap, simple and reliable way to store coins for a long term.

Hi there. New to this forum, but ain't a newbie in crypto world.
I'm trying to popularize the idea of investment in cryptocurrency among small households.

And immediately after newcomer buy his first digital coin he needs to decide- where to store it?

Any questions? Feel free to ask here or on Kickstarter.

How safe is the wallet if or when released? Obviously, using this wallet would mean trusting the wallet's developer or creator. And, most importantly, being convinced that such wallets are at no risk of being accessed via a backdoor system.

I love the idea of engraving both the public and private keys on the card, protected by a passphrase-protected Bitcoin private key. Is it really secure? I mean is there any way to reverse engineer the encoding in any way? Sorry for asking. Just paranoid about these things. I always believe that a private key, encrypted or not and in whichever format it is generated, is only secure if it is known to and controlled by the wallet's owner and nobody else.

If it is really secure and impenetrable, I would love to have one of these cards and will be happy to support the Kickstarter. I do want to see the earlier question answered: what if the project fails to achieve full funding? Would you still move forward with it?



It is as safe as BIP38 encoding. I will not know your passphrase and will not know how to encode your password and gain access to your coins. And BIP38 for now is among most advanced and safe algorithms.
If KS funding will fail I will not produce those cards. Guys, frankly speaking that project is not about profit. It's about advertisment of cryptoworld to new people and helping to solve problems with security for long term storage.
So I still hope you'll support me Wink

Cool idea, and great use of BIP38 to get around the issue of you also having the private key...  I'm in for 3!  Wink  Will you print different icons on them depending on the token choice?  Like if I want a ZEC one, I'm assuming you'll print the Zcash logo on it?  Also, how are you etching them?  I also have a CO2 laser cutter, so I'm assuming you're treating them first with a coating, then that's actually making the marking (similar to dealing with anodized aluminum)... Do you have any issues with it scratching off?

Hi Markaz. Sure logo depends on currency. I have a fiber laser, not CO2. Engraving is very deep ( about 0.2 mm) so I don't need coating and don't have a problems with scratching.
