make sure they are 316 stainless. Zn plated steel will rust under immersion and likely wipe out the inscriptions or worse, zinc will melt and fuse the pile together at only 500C. even SS may sinter in a house fire, leaving you unable to access the stamped faces (destroyed by oxidation), which is one drawback. One way out is to use 625, 800H, 309 or some other corrosion/oxidation resistant alloy. Or utilise registry positions (courtesy of the jig) on the edge of the washer and cut through notches, spelling out a binary or hex code instead of stamped clear text. Only total destruction of the pile would result in loss of that data. But because it is so cheap, you can afford to have multiple duplicates which is the best outcome.... nice work john.
My second backup is buried, with a treasure map hidden in a painting frame, and my third backup I implanted in a patient during their appendectomy... "You have something I need."
Lots of diy options out there and people should use them. What these companies are charging for a simple plate of steel is ridiculous. You could buy a dremel tool, a letter punch set, and a hammer, and salvage a piece of stainless for less money...This is a great opportunity to be creative!
Interesting idea! Thank you for sharing. To improve on this idea, you could drill a hole through the nut and bolt and put a padlock on it. That'll prevent someone from lurking
Had a scare a few weeks back, thought I had lost access to Multiple Meta Mask wallets, only had the primary wallet Seed Phrase (On paper in my safe), luckily I was able to recover the additional MM wallets. I'm glad I stumbled across your content, will now will be getting a stamping kit and washer template and a shit tone SS steel washers, nuts, and bolts from Home Depot. Thanks!
Hiya John, you're a genius Sir. I bought one of those titanium seed stamps. I'm in IRELAND & they only sell them in the US, by the time I paid for postage & import tax it ended up costing 280 Euros,
Glittery nail polish that you've taken and saved a picture of makes a handy diy tamper proof seal. Easy enough to get a nut and bolt that will end up with a relatively flat top or cut the bolt down to size yourself.
This is a good idea. But if you live in an apartment you probably won’t have an anvil or workbench. You might need to buy a small jeweler’s block. You really need a strong and firm surface, and you need to hit with a single hammer strike. Kitchen table won’t suffice. If you’re still having difficulty, try softer copper washers. Also, hold the stamp with pliers so you don’t smash your thumb.
Great idea. If someone finds the washers do they get access to the wallet? Is it possible to add one more layer of security? This is good for preventing destruction of your seed words, but I worry about someone finding it.
Really good and informative video. Got me thinking and being more aware of the importance of keeping those seed words safe and secure. Just seeing all the links in the show notes speaks volumes.
Even if you don’t own a stamping jig or the letters, it’s about $50-60 for everything and you’re able to create 4 wallets using 24 washers each. Still a much better option than spending about $180-200 on an official stamping kit set. I’d recommend storing it in some titanium tube then keeping the tube in a fire proof safe. You can never be too safe.
to be fair and open .... you would have a total investment of $66.35 it is $3.35 for hardware (washers, bolt and nut) $63.00 for the metal stamp kit (Amazon price) .If you already have a metal stamp kit or know someone that will let you use theirs then subtract $63.00
Even with the stamp kit, it is still way cheaper than an "official" metal crypto backup solution...even worst(or better lol) the others solutions are for only 1 wallet
Love the video, great idea. I bought the washers linked in the description but they have too large inner diameter(8mm) and don't work as well. I bought the 6mm inner diameter which is the one you have in your video.
I'm still chuckling that there are folks out here that literally spend more than 100 dollars for just only a sheet of metal with cute little stamps. That's some crazy markup price.
The link is correct, but it seems Amazon has sold out of M8 24x2 and redirected my link to 16x1. :( It will be corrected once the 24x2 are back in stock.
Reason why the default solutions are limited/tight in character space, is because you only need 4 letters of a seed word to be unique :) So no more than that needed to get the right word from the list.
@@jbennison5672 You only need the first 4 letter because the wallet can figure out the remaining letter(s). The first 4 letters of a BIP39 list are all unique.
If you have three backups would recommend you divide those into 2/3 of the seed phrase so any 2 can complete the seed phrase but 1 can’t. Otherwise you are increasing your risk.
The best way to store your keys in metal is with a custom one... All those other ones, people know what they are. But if you customize your own, you can make it look like a piece of some electronic, some even look like car parts. People would just ignore them if they ever find them, or if someone were to brake into your house, etc.
i was going to spend $200 for two fancy looking brand name, but this video just saves me $140 (and i’ll be able to make 4 storages minimum). so thank you!
If you’re not going to hide this amongst tools, use bigger/longer bolts, drill through the bolt beneath the nut once the nut is on with washers in place, put a padlock through the hole in the nut. You don’t want just anyone able to undo a bolt to see your seed.
The idea looks great, but when I tried those metal washers seem way too hard. I have to hit pretty hard and several times even to make a dent, and it is almost never the whole number that is seen. I think the ones I have are 2 mm thick stainless steel, are there others better for this task?
What John did is very clever because it is very unique. Don't do the same thing he did. Come up with your own unique method of encoding information. Could be marks on a wall, placement of trees, placement of floor tiles. Think original.
I really appreciate your efforts! A bit off-topic, but I wanted to ask: I'm using a SafePal wallet with USDT and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). How should I go about transferring them to Binance?
brilliant. I wish I have seen this video before I bought one of those hundred dollar+ fancy ones. but starting from scratch, the stamp kit cost $62, plus the jig, perhaps 75 or so right? Can I ask how long it would take to stamp 24 words?
I think for added security, I would scramble the order of words somehow. Maybe instead of a number on the top of each, file some sort of custom notch pattern in the side of the washers.. maybe like 1 notch on the inner circle indicates a 10, ie seed word 23 would have 2 inner notches and 3 outer notches, while seed 14 would have 1 inner, 4 outer... etc.. Or create something more complicated and sneaky. Just so if anyone else ever found this they maybe couldn't figure out the order right away. Another trick could be drilling a small hole through the open end of the screw, so that you can put a small lock that prevents anyone from unscrewing it. But picking or cutting a lock is trivial if they know what it is I guess.. Best security is just finding a good hiding space for this thing that would be overlooked.
@RC I get what you're saying, but I think the notch idea is simple enough to work and remember personally, but it might confuse a thief who doesn't notice it. And again, like we both said, the most important part is making sure nobody finds it in the first place & you don't lose it. The most complicated password in the world doesn't matter if you store it on a sticky note on your desk lol.
Turn your 12 or 24 words in to other words using a cypher you only know how to crack and then punch those words on the washers.. then if someone finds the washers they need to know the cypher to get the real words from the ones on the washers..
I like the idea of hiding a couple off-site but what about the risk that someone finds them and accesses the wallet? Or would they still need the pin? Thanks, great video.
Hi John - Excellent video - really appreciate all the work you put into this showing us how to do it, and very cleanly. If you don't mind would you tell me the brand and model of your eyeglasses - they're exactly the style and size that I need because I have a high prescription and I would be very grateful if you could share that info. Thank you!
The washers you are using are steel 304 which is fine but not as strong as many think. 904l instead is the one used by Rolex to make all their watches. Does anyone have tried to use 904l washers?
Well, unless you own a 3D printer, you have to buy a metal stamps kit for $60 or a washer jig for $7.99, so this is not $3.35 to begin with. However this made me think of using a DYI instead of buying one of those seed phrase metal storage on the market. I actually think it might be a better idea to use an engraving tool and not being limited to using metal washers. You could use a piece of a metal and engrave your words.
Why be complicated and expensive when you can be cheap and effective? This is really a wonderful idea to keep the words.
make sure they are 316 stainless. Zn plated steel will rust under immersion and likely wipe out the inscriptions or worse, zinc will melt and fuse the pile together at only 500C. even SS may sinter in a house fire, leaving you unable to access the stamped faces (destroyed by oxidation), which is one drawback.

Amazing responce! Could you give an example of a hex code using a washer?
BUMAX fasteners can be custom made to cope with extreme operating temperatures of between -269°C (4 K) and 800°C. McMaster-Carr 5@$8.88......
you could also put stack of washers inside steel pipe capped on both ends for storage and protection
I need this in my life.
How do I get 1. I was using a drill. It takes ages and gives me cramp
@@incognitoalias2808 crazy expensive. 5 for 9 bucks, that's nuts... I can't find anything else that can deal with high heat for a decent price.
My second backup is buried, with a treasure map hidden in a painting frame, and my third backup I implanted in a patient during their appendectomy... "You have something I need."
The One piece map is inside someone abdominal cavity.
This video is worth at least 200bucks. Thanks John for sharing!
If you really want to go nuts on storage time without corrosion you could store these ins sealed container full of oil
Stainless washers.
Stainless steel maybe ?
Much better titanium washers, bolt and nut with lock 😊

This is unbelievably clever. I am going to make a bunch of these.
I would drill a hole through the end of the bolt to accommodate a small padlock.
The less it looks like something worth stealing, the better IMO.

It would just be nice if I had a 3D printer
Great Job! I love the idea. I been racking my brain and this is a nice and clean solution.

So no more than that needed to get the right word from the list.
True, but I like to spell out the full word to remove the guess work on what the word might be. For example: absu or dema, just to list a few.
I don't understand this. How can you just use the first 4 letters of a word on a plate? What if the word is 8 letters long?
@@jbennison5672 You only need the first 4 letter because the wallet can figure out the remaining letter(s). The first 4 letters of a BIP39 list are all unique.
