A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.

What is the Phrasekeeper?
The Phrasekeeper will enable you to backup your crypto wallet passphrase or private key in a durable way against most common environmental influences like fire or water. And you, or someone you care about, will be able to access it, even if you lost all memories of your passwords or aren't able anymore to share them with your beloved ones.
If you have any type of cryptocurrency, you will likely have a wallet or at least a private key as well. At initialization, most wallets will give you a passphrase, consisting of 12 to 24 words, which is your only way to gain access to your coins and tokens, if your wallet gets lost or destroyed.
So you should make sure to backup this passphrase in a durable way.
On one hand, there are hundreds of posts on the internet were people asking for help to get access to their cryptocurrencies after they have lost their passphrases or private keys. No one in this world can help them, since there is no way to get access after one has lost them.
On the other hand there are stories of people who died and their families weren't able to access their cryptocurrency wealth, because with the loss of that person, it's access through secure passwords were lost too.
So you need a good middle way of storing the passphrase save enough so that no one can hack it, but stored also in a way, that beloved ones can access it if something very bad happens to the holder of the wallet.
When you store the passphrase or private key on a plate of copper using punching letters, everyone of your beloved ones can read it, in case of doubt. It can't get hacked, and since you can store it nearly wherever you want, you can hide it somewhere no one but you and your beloved ones would find it.
How It Works
Both editions are fairly easy to handle. When you want to backup a passphrase, pick the Passphrase edition with and just punch the words into the rows.
Private Key Edition:
A private key usually consists of numbers, big letters and small letters. To keep things as affordable as possible, we just offer a punching letter set with uppercase letters, a punching number set and a puncher. You can just use the puncher and punch a dot beneath a letter to mark it as lower case.
Fire & Water
A usual house fire has a temperature of about 600°C (about 1100°F). In rar cases, if the fire would burn uncontrolled for hours, it could reach a max. temperature of about 1000°C (about 1830°F). With a melting point of 1083°C (about 1981°F), copper is a very good fit to withstand those temperatures.
Why not stainless steel or Titanium?
Many other solutions use stainless steel or even Titanium, because of their higher melting points. But it's very unlikely that a usual house fire will surpass the 1000°C (about 1830°F). Maybe it's worth if you're planning to hide your passphrase in an industry furnace, ... or a volcano.
The problem with stainless steel is, that it's so hard, you would need a very big hammer and a really hard and flat surface to punch letters into it. But not everyone has a workbench or an anvil at home to do this. Copper is a relatively soft material, where it's no problem to punch letters into with a standard 300-400 g hammer and the steel base plate we'll put into the sets. So you can punch your passphrase even on a cheap Ikea table into the Phrasekeeper.
The problem with Titanium is, that it comes in different classes of purity. And you can say, if such a plate, made of "995 Titanium" costs less than 20 Dollars, without any engraving or printing, then it's not pure Titanium but more like an alloy, which isn't much better than stainless steel. So the pure Titanium solution would cost a lot in production and even more in retail. Copper isn't the cheapest material, but it's nearly as affordable as stainless steel.
The Passphrase edition is compatible with every wallet, hardware or software, that will give you a mnemonic passphrase with up to 24 words. That's for example the case with Ledger Nano S, Trezor, Cool Wallet, KeepKey, Exodus, Electrum, Coinomi and many more wallets.
With the Private Key edition you can backup a private key of every crypto coin or token with up to 126 digits.
I wrote an article about how I created the Phrasekeeper. You can read it on Medium. Beside the actual metal printing and cnc cutting, I self-made everything else: Prototypes, product design, logo design, photos, videos, voice over for the kickstarter video, website, social media stuff, and maaany many more. And I love it. I never had a project before were I could apply so many skills and things I've learned over the past years. Feels amazing!
I'll create an online shop were you can order the Phrasekeeper some days/weeks after the kickstarter campaign. Then you will also be able to (pre)order a Passphrase or Private Key plate individually. You will get longer screws with these orders, so that you can store up to three plates in one Phrasekeeper. An individual plate will cost about 25€, so it will be relatively affordable if you have more than one private key or passphrase to backup.
I already did and will continue to make deals with other online shops so that you will hopefully be able to order a Phrasekeeper with less shipping costs and less days to wait. We'll see. (If you have an online shop and you're interested in working with me, write me a mail: mail [at] phrasekeeper.com)
Press & Media
I already did a few things in my life. Skateboarding, Playing guitar in a metal band, tried an apprenticeship as a carpenter, was a hobby photographer. But I guess, the most time of my working career I was a web developer. I worked for many companies, some of the time as an employee, some of the time as a freelancer. I co-founded "Android Weekly", one of the largest Android development newsletter in the world. I discontinued working as a web developer for one semester to study geology and worked at the German Aerospace Center (DLR), then I tried to become a famous YouTuber and Twitch gaming streamer (I did became Twitch Partner!). I educated myself about many financial topics and came across Bitcoin and Blockchain, and so I ended up creating this startup. I like to test things out :)
You can join my Telegram channel and ask me anything, anytime (I'm from Germany, so it can take some hours for me to answer, if I'm sleeping). Or ask your question here on Kickstarter. I'm happy to answer all of your questions.
Never ever give away your wallet passphrase or private key. You have to be 100% sure when you do, that it's okay and the person, company or program is trustworthy. No company will ever write you (regardless if via mail, email, facebook, telegram or any other messaging service) and ask for your private key or passphrase. So if you get a message like this, it is very likely to be a scam. So watch out!
You punch your private key or passphrase yourself into the Phrasekeeper. Not me, nor anyone else claiming to be part of the Phrasekeeper team will ever contact you and ask for that information. Never!
Risks and challenges
Since it's my first Kickstarter, but not my first crowdfunding campaign, I can avoid some mistakes I made in my first campaign. It was a near space weather balloon project which reached it's funding goal, and I completed it in time. But I had to find another investor afterwards, to pay some things I didn't thought through when I created the campaign. All went well though and I could gather some great videos from more than 31km (100.000ft) above the earth (I didn't flew myself, sorry). I can send you the link to the campaign or video, if you're interested.
As you can see above, I already went through all the prototyping processes and I took final prototypes to some crypto meetup events around were I'm living. There I let people test it and gathered feedback which went into the final products. It took some months and a bunch of money to get there, but now I can say: the product is ready!
Supply Chain Risk
Since I have to work with suppliers for the punching letters and numbers, the steel baseplate and also a supplier for the Phrasekeeper parts itself, there could be some unexpected delays in production of the parts I need. In this case I would have a second supplier for each in line. Would cost me a bit more, but I would rather loose a bunch of money than not delivering the rewards.
I guess, if the campaign would really go crazy in terms of order numbers, things maybe could (will?) delay. But I would communicate everything, positive or negative, at any time, so you would know what's going on. And if there is a problem, I'll find a solution.
I looked at other projects, and I guess I chose a "healthy margin of safety in my delivery estimates".
