Before The Purchase

Have you also heard these stories of people losing their Bitcoin(BTC) due to fake wallet software or tampered hardware wallets?

Hacks will never stop and security is always a priority. The first step for security is therefore due diligence and research before the purchase.

When it comes to securing your bitcoin, caution and time are your best friends. Don’t trust, verify as the saying goes. You better spend a couple hours more to do due diligence and research a product before you decide to purchase something.

If you fall victim to a scam product, your money is at risk and total loss could be the result.

So what should you know before the purchase? Well, a backup steel set such as Seedor is completely analog. There is not a big chance you could get hacked as there is no digital device or internet connection.

However, let’s think about ways that hackers could actually manipulate a bitcoin backup set. They could have placed small sensors inside the punches that could register shock and send the data via GPS to the attackers. Or maybe a small camera could be hidden inside the box which records you while you punch in your seed words.

There are a number of attack vectors which, however small they might be, you’d be better off to complete eliminate for ultimate security of your funds. That’s why you should do due diligence and research. Read trustpilot and amazon reviews and dig into comparison articles online. Research where the company is registered and if the feedback on social media is positive. Have any experts vouched for them or are they being called out as scammers on Twitter?

Finally, only buy bitcoin related hardware from the original source and not from third party vendors. Eventhough a distributor or vendor can be trustworthy, it’s always advised to purchase products directly from the shop of the manufacturer.

Why Backup Steel Wallets Are A Must Have

The seed or recovery phrase is most critical part when securing your Bitcoin(BTC). Many people don’t realize it, but the real security hole is having the appropriate backup of the seed. The seed or recovery phrase usually consists of 12, 24 or 48 words and allows to recover a wallet in case of loss.

The more technical term of the recovery seed is mnemonic, mnemonic seed or mnemonic sentence. A mnemonic sentence (“mnemonic code”, “seed phrase”, “seed words”) is a way of representing a large randomly-generated number as a sequence of words, making it easier for humans to store. So in short, the mnemonic makes complex data easy to read for humans. In the case of bitcoin, the mnemonic allows us to turn the private key into something you could more easily memorize in your mind.

Whoever has your seed has your Bitcoin(BTC). But how can you protect your seed from all kinds of disasters? This is where steel wallets come into play.

According to Bitcoin(BTC) security expert Jameson Lopp, the optimal steel backup device will have the following characteristics:

  • Stainless steel or titanium
  • Small but thick form factor
  • A single solid piece of metal
  • Center punched / electrolysis etched data
  • Template for decoding data inscribed onto the device

Where To Purchase The Seedor Safe

Once you made the decision hat seedor is a good fit for you, you will want to actually purchase the product. The best place to buy the Seedor Safe is directly at the Seedor online shop.

Seedor: Steel Safe Made In Germany

The Seedor Safe allows to create a robust backup of your seed in a compact, capsule-shaped design that fits in any pocket, safe, lockbox or vault. Or at a place in your home that you consider a good spot to hide your multimillion Satoshi treasure. Don’t forget, this is about generational wealth and a swiss bank vault in your pocket. Perhaps the kitchen table is not the right option to store it.

Another advantage is that the seed is not immediately visible, but only when you unscrew the Seedor capsule and look at the individual plates. Other seed wallets, especially those where the entire seed is stamped onto an unprotected metal plate, are much more transparent, but in a negative sense.

Many will be pleased: The Seedor Safe was developed in Germany and is also shipped from there. This is particularly interesting for customers within the EU. Producst from outside the EU could take a long time to arrive at addresses in countries such as Germany, France, Austria, Switzerland etc.

The Seedor Safe-Starter Set reached us in fairly compact cardboard box. Inside we found a noble, black box, with the Seedor logo.

Inside the box we found the following contents:

– Hammer

– Capsule (Seedor Safe)

– Punch guide

– Punching plate

– Seed discs

– Punches (letters and numbers)

– Instruction manual

– Seal

– Earplug

The Seedor Safe capsule is made of V2A stainless steel. This is fireproof and waterproof as well as protected against corrosion.

Our biggest concern in testing the Seedor Safe was the punching pins and whether they might wear out quickly once some of the discs had been created. Fortunately, we were proven wrong and the punching pins are extremely durable. According to Seedor, the material is the best choice:

The entire capsule and the discs are all made of the same 316 stainless steel. We chose this material because it is very robust, corrosion and temperature resistant, and because it allows for two different types of processing, such as CNC turning of the capsule components and punching of the discs.

If the components were made of different metal alloys, galvanic crevice corrosion could always occur, which we have also ruled out by using the enclosed chrome vanadium punches. Stamp sets from DIY stores are usually made of C45 steel, which is not stainless and thus transfers foreign corrosive material into the discs when stamping the letters.

How The Seedor Safe Works – Step By Step Guide And Insdtructions

Using the Seedor Safe is not rocket science. However, a few things need to be addressed.

First advice, use the ear-plugs, the punching is incredibly noisy. Because of the noise, you probably want to be in a basement or garage so neighbors don’t get suspicious. If you are of the paranoid breed, add other noise sources into the mix, such as the chain saw, angle grinder or lawnmower. You can tell your neighbors you’re working on a time machine if they ask what the hell you are doing.

You should also use a very solid table because otherwise the punching could be less effective.

When you open the box, you should ensure it is complete. If something is missing you should immediately reach out to Seedor.

Seedor Scope of Delivery

Fortunately, using the Seedor Set and creating a backup of a seed or recovery phrase is mostly self-explanatory. You have to punch each word of your seed phrase on one of the steel disks.

So let’s get started. Prepare your mise en place, make sure you have full privacy, no observers or cameras around you. Ensure the noise does not raise eyebrows of anyone and wear ear-plugs for your own health.

1. Place The Punching Pad

After you unbox everything you will lay the punching pad on a solid surface. Don’t use a weak table or a soft surface like a bed or couch. Also remove any textiles from the surface as they could reduce the punching force.

2. Place The Steel Disk

Then, place the first steel disk on the punching pad to punch a word of your recovery phrase.

3. Place The Holder

Next, place the plastic holder on top of the disk. The punching pad has 8 different positions, each assigned to a letter from A-H. When you punch the first letter, you will start at position A, the second letter at position B and so forth.

4. Choose A Punch Stick

Take the right punch pin. If you are looking to stamp the word ‘zoo’ your first letter would be Z. Always double check if the punch you are using has the correct letter. Then slide it into the punch holder. Be careful that the letter has the right position and is not placed upside down.

5. Hammer!

Punch each letter with two strong hammer strokes. After you are done with one word, release the punch holder and closely examine the steel disk. If a letter is not imprinted deep enough you should rework it.

Once you have finished a disc, you will notice that it is no great feat. The only thing you should pay attention to is that all the letters point in the right direction. It can also happen that you don’t hit it hard enough the first few times. But that doesn’t matter, because you can always rework a letter.

6. Pack it up

Once you’re done with all words of your backup phrase, put the disks on the pin of the Seedor Safe. Double check that the words are slided on the pin in the correct order to avoid messing up your backup.

7. Close And Seal

The hard work is over. Now you will screw the cap on to the Seedor Safe and place the seal over cap and safe. This ensures that opening would be made visible.

8. Find A Hideout

The last step is to find the right place to store your safe. You could simply put it inside your home safe. Security statistics and experts are constantly evolving and the ‘need-to-know’ principle is still regarded as smart strategy. This means just put it somewhere nobody would easily guess and don’t share the secret.

How difficult or enjoyable is the Seedor Safe?

While we acknowledge that not everyone will enjoy the process, we believe with the right perspective everyone can at least find some meaning in it. Each word you hammer down on the disk is a step towards individual sovereignty. By protecting your private key you also make the entire Bitcoin(BTC) network more secure as self-custody makes it harder for malicious actors to confiscate user funds.

Just like young boys like to use a hammer, Bitcoiners like to protect their corn in a self-sovereign way. As Trace Mayer used to say “flexing your monetary sovereignty muscles” is everyone’s duty in times of uncontrolled money printing.
