Cryptosteel Seed12 Metal Backup (Protect BIP39 Mnemonic Seed from Water, Fire, Physical Damage)

[@SoftwareWrangler]

Just make them alone for 3$ plus 10$ for the tool. An idea for the next video to follow DIY history 😀

[@CryptoGuide]

Washers and hammers are certainly easy and cheap if that is what you are after ;)

[@martinlutherkingjr.5582]

You’d need to stress test the DIY version. Most people don’t have the ability to do that.

[@CryptoGuide]

Most DIY stuff will be very robust if it's stainless steel. :)

[@martinlutherkingjr.5582]

@@CryptoGuide Lopp’s stress tests in 2018 showed even just a different manufacturer with the same general design can make a difference. Billfodl performed worse than the cryptosteel cassette. Cryptosteel uses 304 stainless steel which has a higher melting point than the 316 stainless steel used in Billfodl.

[@CryptoGuide]

304 and 316 stainless really don't have a meaningfully different melting point, the main issues in his tests have often come down to poor material selection (some that use aluminum, instead of stainless) or when the design itself has problems. (Which is very much the case for cassette style options)

What happens if I accidentally spill all the letters when I decide to open it?

[@mellowtime9712]

Thanks for the video as ever. One thing I don't understand about these kinds of permanent steel wallets is the fact that the seed phrase is left in plain text. That would be fine if it was part of a multisig solution but not for a single sig solution. The tamper-evident seal won't stop anyone taking your coins, they'll just let you know that someone has been there. The emptied wallet would give you exactly the same information. Not all family members are trustworthy! What I would like to see is a system where you can mix up or encode the seed phrase somehow. The instructions for decoding can be in a separate location or even multiple locations. It would be the equivalent of password protecting the steel wallet. [This would of course be in addition to other electronic hardware wallets so there is no single point of failure.] Or given your experience of helping people recover wallets, is this a step too far?

[@CryptoGuide]

Thanks for the comment :) Basically if you want to add a layer of protection to a 12 word seed backup, this is best done via a BIP39 passphrase.

[@dave47663]

Agreed. Use a BIP39 passphrase.

[@mellowtime9712]

Yes - that makes sense! Thank you.

[@CryptoGuide]

No worries, just be sure to include your passphrase in your backups somewhere too, just not with the seed words ;)

[@mellowtime9712]

​@@CryptoGuide Don't worry - I'm paranoid!

[@K28438]

Hi great videos, I was wondering if you could make a video setting up a block stream jade with sparrow airgapped and setting up a watch only wallet through sparrow ? Thank you

[@CryptoGuide]

So would you intend to have the Jade initialized with a seed and be doing the QR unlock thing or would you be looking to run the Jade statelessly? (So load a SeedQR each time)

[@Давид-и8н]

Hello! How safe are the fasteners at the beginning and at the end, an accidental opening is possible and that the words will sleep?

[@CryptoGuide]

They are very firmly closed, you would need to cut them off or prize them open with plyers to get them off. (It isn't going to happen by accident unless you didn't compress it flat to start with)

[@Давид-и8н]

@@CryptoGuide thanks for the answer

[@CryptoGuide]

No worries

[@SoftwareWrangler]

Wooow new Specter 🤔 When sir?

[@CryptoGuide]

The first batch of fabbed hardware should arrive this week, so I will be sending it out to those who want to give it a test next week some time :) (If you want one to test, just shoot me a DM on Telegram or Twitter and we can work it out)

[@oragngeva4808]

Hello, Im missing 1 word for my cardano (shelley era) wallet. I dont have the address for it. Is there a way to go about this?

[@CryptoGuide]

BTCRecover doesn't currently support creating an AddressDB for Cardano, but could likely be added through a direct feature sponsorship. At the same time, if you are only missing a single word then it would be straightforward to code up a custom script to do this.

[@ahmadibnussina7038]

please review SafePal Cypher

[@CryptoGuide]

It's just a clone of the original cryptosteel casette and has all the same issues of the tiles falling out of the casette itself is deformed.

[@chadwick7176]

Hey i need help i was using robinhood and sent etc to the samsung blockchain wallet and it's lost because samsung blockchain wallet doesn't support ETC. can you help me please

[@CryptoGuide]

As long as you have the recovery seed, that is a straightforward recovery. Just follow my video on recovering from sending funds to the wrong blockchain for Eth clones.

[@chadwick7176]

@CryptoGuide still the same because when I sent "crypto" from robinhood to the samsung wallet I clicked received and pulled the address to the ethereum wallet address. So is that still the same process

[@CryptoGuide]

Yep

[@chadwick7176]

@CryptoGuide I'm confused I'm watching the video and you said if I have crypto stored on an exchange I can't get it back??? Idk i need more help 😩 I was using robinhood investment not there wallet app and I sent etc from robinhood crypto to my samsung wallet and sent it to the ethereum address

[@CryptoGuide]

That's right, the recipient was a normal wallet with a seed phrase on your phone, so it's a straightforward recovery. (Doesn't matter where the funds originally came from)

[@martinlutherkingjr.5582]

The security wire seems like kind of a gimmick…can’t an attacker just get some of that wire? There’s nothing unique about it from what it appears.

[@CryptoGuide]

It's about being tamper evident. One of the challenges with private keys and stuff is that someone could have your keys, but choose to wait until a later date to rob you.

[@martinlutherkingjr.5582]

@@CryptoGuide Yeah, but if an attacker has some of that wire they can just re-seal it so there’s no tamper evidence. The wire isn’t serialized I assume.

[@CryptoGuide]

The wire is distinctive and the yellow clamp at the top can't be reused, once it is locked that's it.

[@M.J.C.W.]

So this is just a fancy way of writing your password down on a Post-it note under your keyboard?

[@CryptoGuide]

A fire and water proof way, that you would want to put somewhere better than under your keyboard, but yes :)

[@martinlutherkingjr.5582]

Is your post-it note made of steel?

[@CryptoGuide]

Probably not ;)

[@CRYPTOPIAN.S]

is that possible to recover lost 3 recovery phrase with btc recover tool ? i lost on of my solana wallet

[@CryptoGuide]

If you know the location of the missing words then recovery of three missing words is no problem.

[@anzo06]

seems risky if a kids open it and shuffle the letters. all is gone.

[@SoftwareWrangler]

I don't see how this could be made more unfriendly

[@CryptoGuide]

Kids tampering with stuff is a real threat, but if they get their hands on a stamped steel option then they might just throw it in the bin or leave it lying around... Store this stuff out of reach of your kids :)

[@dave47663]

Have more than 1 in different locations. Different geographical locations is better.

[@CryptoGuide]

Geographic distribution is great and is much easier to do safely with the addition of something like a BIP39 passphrase, SLIP39 or multisig
