Topic: Securing Your Seed Phrase with Washers - page 14. (Read 5896 times)

You don't need to heat the seed phrase to be able to stamp them in a washer and also there is absolutely no reason to stamp the seed phrase in your gym equipment If your welder tells you that only he can stamp it because it needs to be heated I m 100 % shure he wants to steal your coins in the future. So send all your funds to a newly generated wallet with a different seed phrase ASAP. Take that new seed phrase and secure it secretly, not in plain sight on your gym equipment.

So you gave your seed phrase over to someone else and had them engrave the plates for you? That's a big mistake! If you have any coins on the seed phrase you handed over you should move them ASAP.

I have to say as well, those weight plates look like cast iron without any protective coating, and they already look pretty badly rusted. I think there is a risk of your seed phrase becoming illegible over a long enough time frame here.

Heating your stamps will weaken them. If anything, you can heat the washers, but those metal stamps are designed to be used on cold metal. They're hard enough, just hit them with a hammer.

Another idea: You need to carry a bag full of weights with seed words on them and if you manage to cover a set distance, you're allowed to open it and your prize are the seed words. Olympic games, Bitcoin style.

Something like this!

So you did have someone engrave / weld a seed phrase into them? I see you censored something on them.

Your welder had to heat his tools to get the seed phrase into the weights or do you mean that fillippone heated his stamps for stamping washers? I wouldn't recommend to heat up 'washer-caliber' stamps, because it would damage them. It's certainly possible that that's required to stamp actual freaking gym weights, though...

That's pretty creative, I'll give you that! Never would have imagined engraving barbell weights with a Bitcoin seed phrase.
Now, that makes me think there are tons of other, more easy to stamp and conceal, metal 'things' we could stamp.

I believe someone mentioned stamping an actual door hinge, before screwing it into the wall, for instance.
You could probably also stamp your car's frame underneath the carpets or engrave some actual metal coins, maybe stored together with other coins in a piggy bank.

I smile sir. Sir please don't be confused. Although I did not explain the irons well for easy understanding. I was trying to give example of my understanding of your thread that, I got a similar disk from a welder. I Know for sure that they are not washers but washer look alike. And also they are bigger than washer.  They are barbell weights, even though the welder uses them to print the seed phrase, I believe I can't secure or hide the seed phrase because it is too big to hide seed phrase.

As for the oven. I was trying to say that, from your presentation, you gave the examples of the tools used in printing the seed phrase, I know before you print the seed, you must heat (make it hot) your Stamps either by light, gas, stove or charcoal to make it very hot before using the anvil and the hammer to make the printing less stressful.

I really appreciate your presentation and also today I came to know about washers which can be used to secure seed phrase although it will be very difficult for me to have washer in my village but that not withstanding I can use something else to secure my phrase and also present it here. So don't be confused. I am your boy that always learning from you.

Securing Your Seed Phrase with Washers takes it to the next level. This also has its advantages: thieves will definitely not steal your seed phrase, because they simply can't carry it away. Sorry, I couldn't resist saying that.

Oh yeah, what would be the total weight of the vault if you wrote one word for each washer dumbbell disc?

This picture sparkled with new colors in this context?


I hope that this was a joke from Agbe, because in this thread the dimensions of washers were discussed many times, which in no way could be confused with dumbbell discs.

Theoretically, if Agbe so desires, let him use GYM discs to store seed phrase. He just needs to figure out a way to hide what he wrote and Agbea can be awarded a prize for the most original way of storing seed phrase. Personally, on my own behalf, I award him merit. He deserved it.


This is easily done with a dremel or laser engraving. Agbe shouldn't have any problems with the laser, because he has already found welder. Sorry again. This story still makes me smile.

That's the idea. They will start the competition from easy 6 word seeds, then average 12 word seeds and at the end the most difficult seeds 24 words.
Additionally there may be one more task - Tower of Hanoi build from seeds.

I have seen those “strongest man” competition where you are supposed to lift spherical stones,  turn gigantic tires or stuff like that. News year the prize will be awarded to who will be able to print a seed phrase on those barbell weights!

Probably the actual barbell. Everything in the picture looks like barbell parts.


He probably had to heat the tools to be able to dent the barbell weights' surface. But I'd really like to see how the words look like; even if it's a single letter.

I am wondering how wasn’t clear what a washer is and how bit it is.
 I also wrote in the article the actual size.
To be honest those look quite similar to barbell weights, but isn’t a bold the object peeking in the bottom right of the picture? Is that a giant bolt?

In addition to that, what is the oven story?

Ohhh no no no no - if I didn't know your handle, I'd assume your post to be sarcastic.
I think you totally overestimated the size of what we call 'washers'. What fillippone and I are using are small metal discs, between 20 and 30mm in diameter and 2-3mm thick. They are cheap to procure, easy to stamp and compact to store and conceal.

How do you plan on hiding seed words stamped on actual barbell weights? I also assume they're pretty expensive to the washer backups we're talking about here.

It sounds like you're trying to write a school essay.

Those are dumbbell discs. And they're big enough to stamp all your seed words at once.

I don’t know if I understand right, but both anvil and stamp don’t need to be heated for stamping. All tre process is done with cold instruments.
I would have told you to do so.
Also, your washers look quite different from the one I used. I never saw a washer with borders. Are you sure are you using the right tool?

In any learning, understanding the author's mind is the most important aspect of the book or in the reading process. Especially when the content is not familiar with the specific field of your study or the content in the context. From the OP's analysis of the, it was not easy for me to understand. I read the article for about 2 times before really getting the real message of the author. And I have understood it to the core.

First of all, I really appreciate your effort of getting the washer to secure your seed phrase. It is one of the best Wallet security apparatus I have seen. I was planning to get it in my locality but what I have is different. And the printing process is stressful. It takes days to complete the process though it all depends on the printer.

These are the most important objects of the printing. Heating the printing stamps and the hitting the anvil needs very hot oven or light to do that.

I got it from a welder in my location.

I slightly edited the OP to correct some repetitions, typos and other horrible errors.
Thank you, @gazetabitcoin, for helping me sort out that monstrosity and making my posts even better.

For most people you would assume high temperature resistance would be preferable. I imagine most ways that people store this won't be at risk of coming into contact with corrosive substances. However, a house fire is much more likely. House fires might not be enough, but I guess it depends on the specific circumstances of how its stored. For example, storing your backup in your garage which has a ton of fuel around could increase the risk.

I will say one thing though that its time to put on your tin foil hats. Don't store your washers in your kitchen cupboard that has anything with chlorine in it . Chlorine will eat away at your stainless steel as its particularly vulnerable to it. It's worth mentioning that your tap water could potentially have low levels of chlorine in it, so if you have a pipe that could be dripping onto them for a while, obviously depending on how you store them, over time you might have a issue. Though, drinking water is usually has a very low concentration of cl2. Although, some places might be more than others. 1-2 parts per million could potentially give you that corrosion over time, and that's obviously ignoring the damage the water could do itself. Anyway, that's my tin foil rant over.

The point I was trying to make wasn't that chlorine in particular is a problem, but rather don't store your washers in random places in the house that have corrosive substances near them. For example, not everyone wants to put them in a capsule, and not everyone wants to store them together. So, they might opt to place them all around the place, to make them look quite innocent to anyone looking through your house. For example, a thief isn't going to even look at a washer that might be in your kitchen cupboard or your garage.

To me, 304 is going to be the one that makes the most sense for most people.

That's always great; any sort of redundancy is really mandatory.

Something like this?



Thank you so much for looking this up; I originally went for a cheap SS that I had in my local hardware store, but I'll add this to my topic so everyone can buy according to their needs. I would agree that exposure to salt water seems like a relatively likely scenario in many places of the world, so it's well worth considering.

It's not like you are going to drastically reduce size by doing this experiment, and you are increasing chances of mixing up correct ordering of words that could lead to losing of your funds.
Stainless steel washers are dirt cheap, you can buy them anywhere in your local areas, so reducing cost is not appealing enough for me to do this.

When you are talking about extreme weather conditions, I don't know if you know this but 304 stainless steel can easily be corrupted if exposed to salt water, so if you are living in area near sea water I would opt out for better 316 stainless steel.
I am not sure if Jameson Lopp did any tests with salt water, but I believe that is much more realistic threat for some parts of the world compared to acid exposure.

Not all stainless steel is made the same, there are different types and grades, so while 316 SS is better for salt water it does have slightly lower melting point compared to 304 SS:

Grade 304 melting points: 1400-1450°C (2552-2642°F)
Grade 316 melting points: 1375-1400°C (2507-2552°F)
Grade 430 melting points: 1425-1510°C (2597-2750°F)
Grade 434 melting points: 1426-1510°C (2600-2750°F)
Grade 410 melting points: 1480-1530°C (2696-2786°F)
Grade 420 melting points: 1450-1510°C (2642-2750°F)

Pick 304 if you want high temperature resistance, or pick 316 if you want high corrosion resistance.

Each of us can pursue different goals, and in this case, for some, legibility /readability will be important, for others, compact storage. The choice of method for preserving a seed-pharse
 will depend on the goals pursued by each individual.

I understand your concerns about the possible loss of backup data and therefore I suggest that need to make several copies of it.

I mentioned this above, but thanks for expanding my vision with your comment.

I don't think that extreme conditions will affect the readability of the text, because the washers fit snugly together and the construction looks solid and reliable. You need to make a lot of effort and pursue the specific goal of spoiling the text in order to be able to do this.

I'm also more inclined towards having a duplicate of the same seed-pharse and stored in completely different locations. The short version of the text is in easy and immediate accessibility, the full version is in a safe and hard-to-reach place.


Your point of view is clear. But you can't help but agree that putting text on both sides of the washer will not affect the quality and safety of the seed-phrase in any way. Because the thickness of the washer allows to apply text in this way without any damage, and this will positively affect compactness. Noticeable advantage.


Any important information (the text is easily divided into numbered washers) can be stored using such storage. Ways to hide washerss are only limited by the man's imagination. For example, you can use washers for its intended purpose (assembly of products, structures or decorative elements) by putting text on the inside. Who would ever think to check every detail that caught their eye, what is on its inside?

That's why I prefer to have 2 different backup systems in place for the same data. I do of course test both systems independently, to see if I can recover them (before funding).

I couldn't help but smile at the thought of going somewhere, suffering under the load of all your Bitcoin backups
