Make sure you use 304 Stainless Steel or better for your washers, bolts, and nuts!
Also, be careful when reading these comments. The bots are relentless. I will not ask you to contact me on WhatsApp. Do not click on any links for Crypto advisors. They are all scams.
I hear a lot of people saying this, however I've torture tested zinc plated steel to the point where they glow red from the sustained heat, and after they cool, still easily ledgible. I'd say, having stamped seed phrases on ANY metal medium is better than not having any or having paper based backups. Your odds of house burning down are low, but the odds of having your house burnt down by an industrial furnace are less ;)
Great job. You can save some stamping time by only using the first 4 letters of each word. The BIP 39 list of 2048 words were chosen in that the first 4 letters are unique.
Exactly what I did 😊
What will we do without youtube and people like you! Thank you.
one of the best DIY videos that I've seen
Super safe, taking security to the next level! Thanks for the content.
Beautifully done Kindness. I've been looking to do this and this video was very helpful and straight to the point. Appreciate you sir 🤝
Security is so important. Thank you for the video
Great vid! I just received my stamp kit yesterday! Weekend project coming up! 😎👍
That’s awesome Jeff!
That was very helpful. Thanks. 👍🏽
That is cool little red jig.
Amazing tips, thank you very much.
Great video! I literally just told a friend about this method, I'm going to share this video!
Thanks!
This is a great tutorial! Thanks Brother!
Fantastic video!! Thanks!
Great content. Thanks.
Thanks for this! You may want to store your washers somewhere else since you told us in the video where you keep them. ✌️
lovely!
Great information. 👍😎📈💥🚀
Very very important video Ang very helpful vid sir thank you
thank you so much this is a very good DIY
I appreciate people who take their time and energy to share life saving info as this. I am so very grateful sir. This is the best thing I have learned so far this year. God bless you sir
Thank you for the feedback!
nice🔥🔥
Amazing, it maybe costs the same as 2 trazors/ledgers 2022, but for sure worth it. Much easier than I had imagened. But you also got the perfect tools. Even stamps with letters...did not know they existed. Great Video!
Thank you!
f**king genious, thanks alot
I made these and put mine on a padlock
Great video. What size stamps do you use? 5mm?
Tig weld the nut at the end so they won't come lose and it will also serve as a seal.
Wtf am I doing wrong that it takes several, like 6 or 7 wacks with a 3 pound hammer and I still get crappy impressions.
Do you have something solid under the washer? Doesn’t work well on wood or carpet.
Can i hammer both sides of the washer?
Thanks for the help. Now I have my seeds stored without a crypto company name on it.
how thick are the washers?
Amazing ideas. Great content. It’s a little easier though if you take an old license plate, flip it over and stamp it on the back with a $10 stamp kit from harbor freight.
What wud happen to that in a fire
What WOULD happen in a fire? You WOULD still have your seed words, because you stamped the letters into metal.🤯🤯
@@chrisholmstrom2859
Not sure yer bit of tim wud survive
@@paulhelmn9889 Not sure you’ve ever seen a license plate after a car fire. They survive pretty well actually.
Yes, it would survive a fire, but how would you secure/seal it from prying eyes?
👌😎👍
Thank you brother. I appreciate you🙏🏽
You are very welcome
Great video but FYI if someone has half your seed phrase it's much easier to hack. It's not half as easy it's thousands of times easier if you know what you are doing. for example 128bit encryption is not 50% easier to crack compared to 256bit encryption it's WAY easier
Very true. But they’ll never get the 25th word.
@@cryptokindness4504 Still incredibly easy to brute force. Given equivalent entropy, a blockchain address is much more crackable than a typical web-based password as there's zero attempt caps, rate limiting, or even network throughput involved.
If we divide into 2, what about if you lose half set of it? Should we make 2 copies and then split into 4? What do you suggest, thanks
That’s a great question. Make multiple sets and separate them geographically.
Will 4 mm owden stamp kit work instead of 3?? 4mm and 5mm is only options in your link now
If you plan to use the jig then 4mm is too big.
Thanks CK…. The link for the 3D file doesn’t seem to be working though.
Appreciate your videos! Can’t wait for Pulsechain launch!
Thanks for that feedback. I have fixed the link. Please let me know if you have any more issues.
You say that if you buy a seed storage plate, that if the client database is hacked, then they know you have crypto. What do you think happens when Blockmit gets THEIR client list hacked? Same exact thing.
get a hardware wallet that will allow you to add a 25th word. This secures the wallet in such a way that theyll think they have your seed phrase and you can even leave a small balance on it as a decoy, but adding the 25th word creates a whole new set of addresses where you can have your real balance. The 25th word should be something youll really memorize so you dont write it down anywhere or at least dont keep it together with your 24 word seed phrase otherwise defeats the purpose
This!
@cryptokindness4504 Thanks for this great video!
Question; what kind of material is used for the jig, do you know (as it schould not bounce or break when you hamer it)? PLA, PETG, ASA, ASB?
Thanks for answering 👍
Are there any good 3D printers recommended for this jig or anything general purpose?
The only thing better than a good 3-D printer is a friend that owns a good 3-D printer. My neighbor printed them for me so I cannot comment on this.
Hey thanks mate. Can you tell me if we can use upper or lower case letters or are they not case sensitive?? If we order these blocks we will go onto a contact list as well and make us a target in the case of hacking?
Not case sensitive. That’s a good question about ordering the jig and being on a list. I just had a neighbor print it out for me so I had not considered that.
@@cryptokindness4504 have to try and find someone with a 3D printer then.
What size metal stamps did you use?
3mm. Everything you need is in the video description.
Ledger was hacked a while back, and i think through that my info (from ordering a nano s) was available for criminals to use. They did a SIM swap hack with my phone number, got into my email accounts, and tried (but failed) to blackmail me, demanding i send them some Bitcoin (i then asked if they would accept DOGE instead. They said they would, blind to the fact i was trolling them).
So the risk of ordering things from these companies offering crypto related projects is real.
Crazy story. Thanks for sharing.
Make sure to use 24 words seed and split it in 3.
A 12 words seed phrase split in 3, if someone finds a 4 words set, it will take him... 109 seconds to access the wallet !
A 18 words seed, with a 4 words set will take 3 years
A 24 words seed : 3,830,854 years !!
How did you end up with 109 seconds ?
ChatGPT doesn't think so. :
With a 12-word seed phrase split into three sets of 4 words each, if a hacker gains access to one set of 4 words, they'd need to brute force the remaining 8 words.
Using the BIP-39 standard for seed phrases, assuming the attacker knows the structure and only needs to guess the missing words, there are
2048 raised to the power of 8
possible combinations for the remaining 8 words. This is an immense number, making it virtually impossible to crack within any practical timeframe using current computational capabilities.
Estimating the exact time is challenging due to the sheer magnitude of possibilities, but it would take an extremely long time, potentially millions or billions of years, depending on advancements in technology and computational power.
@@majorart9283ChatGPT simply lives in the past 😜
Great video. What size stamp do you use?
The stamp set is linked in the video description.
@@cryptokindness4504 yes but there are 3 to choose from.
3 mm
Great Video. Looks like the link for the washers is not the right ones. Maybe it changed because the ones it links to are too small.
Thank you. That seems to happen often which is why I also write out the sizes next to the links.
very cool! but honestly, we need a better digital for derec keys.
Agreed!
crypto cloaks is asking for my email which is a 3rd party risk like you talked about in the video???? is crypto cloaks safe?
I have not looked in to Crypto Cloaks so can not answer your question. You could always create a generic email to use for ordering.
@@cryptokindness4504 is it even necessary cant you just hammer the letters in by keeping your hand steady?
You can hammer the letters in without the jig. I just like how clean the jig makes it.
Sorry, but it is UNIVERSALLY considered less secure to split the seed phrase in two. There are many articles about this. Don't do it.
I think i'll do that but instead of the words i'll put the BEP39 number instead. i more step before being able to decode ! :)
Great idea!
Where can we buy a blockmit if we don't have a 3D printer?
The first link in the description.
@@cryptokindness4504 I’m an idiot, don’t know why I missed that! Thanks!
So I have a question: if a Ledge Nano X has three different accts for btc, eth & sol... Is it still one 24 word seed phrase?
So if you were to do a seed phrase recovery one day into a diff type of device, say a trezor wallet... Will the same seed phrase once again give access to all three different cryptos/accts the ledger had?
Yes.
@@cryptokindness4504 thanks for the reply mate! Since Ledger is not open-source would you say it's not as "safe" as say a Trezor? Would u at all be concerned Ledger will exploit a backdoor to 'steal' coins?
It’s a personal choice. If you’re more comfortable with Trezor use that.
Are seed phrases case sensitive?
No
Were find blockmit jig?
Check the video description for a link
Not going to melt and dissapear? I dont know... if your on land the government wants, just remember they have special tools that can melt car rims.
He forgot to mention the 500 dollar anvil he used
Please don't split your seed into multiple parts, if a hacker gains access to 1 part of your seed it is alot easier to brute force your full seed. This video will explain why seed splitting is a very bad idea; czcams.com/video/p5nSibpfHYE/video.html.
If you want to split up your seed, you should use Shamir backups instead. The Trezor model T supports this backup method.
Very similar to the John Chow video I just watched.

Aside from divide the seed phrase into 2, the shared one and the one you keep, make a copy or 2 of the shared one, this way if one people get mad at you, you can still get the other half from sb else. Because they cannot access to your money but can prevent you from getting access to your money. When people get mad may want harm you. So make a copy of the shared part and give to 2 or 3 differen people who are not related preferably. (Aside from the fact they can lost it, so i recomend as many copies as posible)
how thick are the washers?
