Bitcoin Steel Wallets gibt es viele - warum Seedor?

There are many Bitcoin Steel Wallets - why Seedor?

The idea of storing valuable information in durable material is of course not new, nor is it ours. The best-known example of this are probably the Golden Records, which are mounted on board the interstellar space probes Voyager 1 and 2. Image and audio information is stored on a 30-cm gold-plated copper disc - in the hope of one day being able to pass it on to potentially encountered intelligent life forms as they travel through space.


And even more specifically on the subject of Bitcoin, there are now a variety of products that allow the Bitcoin seed phrase to be stored in resistant materials such as stainless steel and titanium. Before we set out to develop Seedor, we tested many products available on the market and roughly divided them into the following two groups for us.

Group 1 - "the braille code generators"

These products usually consist of a simple steel plate, which is provided with a laser engraved matrix of letters and numbers. With the help of a hammer and a pick, the user can then mark the respective words of the seed phrase in the matrix. This is a simple and inexpensive solution. In our opinion, however, it has significant drawbacks in terms of readability. And somehow this solution doesn't feel really secure to us either, since the wallet can quickly be rendered unusable with a few more hammer blows, and an accidental mispunch during embossing can't actually be corrected. Another criticism is the inefficient use of space, since the entire alphabet has to be mapped in the matrix for each digit in each word of the seed phrase, you carry around a lot of unused information on the storage medium.


Group 2 - "the alphabet soup."

As far as the use of space is concerned, this product group is already quite a bit more efficient. Pre-stamped letters in miniature size are supplied, from which the seed phrase is replicated in surgical precision work and usually inserted into a cassette element, which is then finally locked. Without tools, this allows the Bitcoin back-up to be created in a relatively short amount of time. However, we really could never get completely comfortable with this system, since an unintentional opening of the cassette (e.g., by a curious child) would most likely lead to the irrevocable loss of the seed phrase and thus access to its Bitcoin. In addition, this system quickly reaches its limits when subjected to thermal and mechanical stress. In the famous Metal Bitcoin Seed Storage Review by Jamesson Lopp, some providers of this system failed.

Even if this may seem so at first, we do not want to criticize other systems at this point, because their use or the storage of the seed phrase with the help of the described product groups is already many times more secure than a back-up on paper. We just want to show that for us the perfect solution had not been invented yet, which finally moved us to start the Seedor project.

So why Seedor?

With Seedor Safe, we wanted to create a Bitcoin seed phrase back-up that would meet all of our requirements for quality, security, durability, and ease of use. In doing so, we set the following goals:

1. 100% protection against external influences and generation-spanning durability.

For a durable and resistant storage of the Bitcoin Recovery Seed, metal, especially stainless steel, is a good choice. The material is resistant to water, fire (up to about 1450° C), corrosion and mechanical stress. For Seedor we use stainless steel type 1.4301 certified according to EN ISO 9001. All elements of the Seedor safe as well as the corresponding discs are made of exactly the same alloy in order to exclude contact corrosion and thus to guarantee durability over generations. We could also offer the Seedor system in titanium, but we deliberately started with stainless steel, since titanium objects are rarely found in the house and can be quickly located with a metal detector precisely calibrated to longitudinal frequencies. Stainless steel offers the advantage here that it does not stand out from the rebar.

2. Possibility to restore the seed even if the hardware is opened or destroyed.

It goes without saying that the seed back-up should be kept in a safe place without any possibility of access by third parties. Nevertheless, we can imagine moments (e.g. the interested child who found out the secret hiding place, the already mentioned inheritance case and a non-specialist heir or simply two left hands and a bad day) when the possibility of opening the Steel Wallet represents a significant security risk.
To exclude this eventuality, we have designed the Seedor Safe in such a way that even in the event of the wallet being opened and falling apart, the Seed Phrase and thus access to the Bitcoin would not be lost. This was solved quite simply by using one disk per word of the seed phrase and then stamping it with the respective number according to the sequence in the seed.


3. Emboss seed phrase in full length - and in the smallest possible space.

In the BIP39 encryption standard, knowledge of the first four letters of each of the 2048 possible words is sufficient to recover the wallet. In many hardware wallets, even after entering the first four letters, the seed word in question is automatically displayed. And yet we wanted to design our Steel Wallet in such a way that the mapping of the entire seed back-up is possible with the full word length in each case.For example, if the entire information is stored in the back-up, this could make it easier to pass bitcoin to descendants in the event of an unexpected inheritance, without the need for additional explanation of the facts. If you use electrum you will also have noticed that there are still legacy words in addition to the BIP39 Standard (Happen, Happy and Happiness),as well as the possiblity to extend the seed phrase with aditional words, which requires to store more than the first 4 letters.

4. cost-efficient option to create copies of the back-up or additional wallets.

What is better than one bitcoin back-up? That's right, two Bitcoin back-ups. We are a big fan of great security and risk mitigation. If you are really serious about it, you should double-secure your seed phrase. In addition, it is advisable not to store all Bitcoin on one wallet. If you follow both recommendations, you will need at least four backups. Since Bitcoiners are known to be rather reluctant to spend money that they could also save in sats, we have designed the Seedor system so that the acquisition costs for each additional back-up become relatively cheaper. At the beginning there is the one-time investment for the Starter Set. The Seedor safes in bundles or three-packs come with a volume discount and are cheaper than all the other market players.



5. All-inclusive Set - "Punch & Play"

Yes, there are numerous creative and good ways to create a Bitcoin back-up in classic DIY fashion. But real Bitcoiners know - time is money. Next block, tick tock. That's why we have set ourselves the goal to provide you with a complete set, with which you can get started right away without spending a lot of time and without additional shopping activities. The individual components are precisely matched to each other and thus enable a precise and ultimately visually appealing Bitcoin back-up, which you (provided you hodled) will enjoy for a lifetime. And if you've been guarding your Bitcoin for the next generation your whole life, you should also pass it on in a stylish form worthy of the occasion.
Last but not least: why is there a hammer in the starter set? Yes they really exist - frugal Bitcoiners who don't own a hammer. Then there is a larger group that does have a hammer, but only with a 300 g head. However, a really good minting result is only achieved with a 500 g hammer - that's why (and because of a little Easter Egg, which we definitely didn't want to deprive you of) the hammer is included in the Seedor Starter Set.


The SEEDOR (the "Seed Tresor (Vault)" is from our point of view the perfect solution for a secure Bitcoin Back-Up, which allows the user to mint the Bitcoin Recovery Seed of any hardware or software wallet in a space-saving way in massive stainless steel and is thus absolutely secure against external attacks ready to last for generations.
