@@CryptoGuide I just put one together with the PN532 module and its working well! after I figured out I needed to physically enable I2C via the switch on the board (doh!). Having an easy secure way to flash the cards and then also transfer the seed to card in such a small footprint package is really awesome. Good work!
@@chaosreigns4390 Nice work getting it going via I2C, I really like the form factor as well. I forgot to mention the dip switches on the board in the video, so will have to add that to the documentation ;)
What a great way to securely manage seed phrases and passphrases - especially in a multisig setup when there's so much to manage. Thanks for your contributions. I wonder if this could be done with Krux.
Is seed keeper just a storage for seeds to sign wallets? Or could it also be used as an account/ card info/ password saver. Is it possible to have both an air gapped seed signer and password manager in one unit. I'm sure it could easily be done with note but I'd like something with a nicer UI.
@@CryptoGuide it was weird when I down loaded everything- Nothing was working giving me all sorts of reasons: power cut off, reader, different device, and then when it stated that it was already loaded but could not do anything error after error, etc. Then I realized (don’t know how) I have to uninstall an uninstalled applet???, and then I figured out if I installed the Satochip or Satodime applet 1st then the SEEDKEEPER will install successfully 😀. Might be faulty reasoning but that is what I had to do and then I could uninstall the Satodime/Satochip and all was perfect. Then this became 🤩. I ordered the Amazon DIY CARDS you left a review on. Satodime worked on my daughters iPhone 11 but for whatever reason it does not register on my iPhone 7… When it was loaded on her phone it stated not authentic ( I guess because it’s not from Satochip proper 🤷 but It still worked as it should - I don’t think I would ever use it but I wanted to see… AnywAy, thank you for the video - time flies I started and midnight and now 5:00am FTW 🙌🏻
The other coolest feeling after going through all this was when I went to sparrow and it so simply loaded and I couldn’t believe it. My daughter and I was like 👍🏻. - what a beautiful project we shared😊
Haha nice, yea NFC stuff is still a bit inconsistent with some older phones but it generally works well. (And some DIY cards can be a bit temperamental when first installing applets) Good job sorting it out.
On the raspi4 design with the interference issues, did you try any metallic shielding, maybe on the back of the display hat? I have no idea if that would help, just wondering
I haven't tested extensively yet, but the issue is that NFC isn't a normal wireless communication protocol, but is also a wireless power transfer mechanism, so adding shielding could actually make it worse... I am certainly keen to explore options around antenna placement, etc, more, but decided to stick with something simple and focus on the software side first :) (NXP have a few hours worth of videos on NFC antenna design that I haven't gone through that would cover it all and take the guesswork out)
Hi, I'm writing to you from Italy, thank you for your very useful videos. I purchased and modified "SeedSigner" with the Seedkeeper card. How can I delete or modify the data stored in the card (seedkeeper)?
Basically you can't delete individual secrets from the card, but you can reset the card by either using the reset function (which isn't currently included in seedkeeper+Satochip) or by uninstalling and reinstalling the applet.
@@CryptoGuide Thanks for the answer! However it is not comfortable at all, not knowing it I have inserted test seeds and several tests. I also saw that it is not possible to change the name associated with the secret. I use seedkeeper via USB with a reader, the P532 module on amazon Italy I have seen that many do not work with raspberry P0. Where can I buy it?
@@lucgiver That's right, secret names are also fixed. Any PN532 module that has the I2C connection will work (And they generally looks the same as one I showed in the video)
Hello and sorry if I disturb you again, I wrote an email to support but they don't answer. I entered the wrong PIN of the seedkeeper card several times and it was blocked. Now he asks me for a PUK but I don't know where to get it. Could you help me? Thank you very much in advance. Luca Rossi
@@CryptoGuide so basically you can store seeds on a satochip and then gaplessly sign with seedsigner? Is there any difference between the satochip en the blank satochip they sell?
This is not necessarily true if you only used the chip with the signer and entered all of the info manually, and never use that chip with any other non air gapped unit.
He is likely assuming that the chips would be used with other non airgapped units. And would be correct if you used a non airgapped unit to save that Info and transfer it to the signer. However I beleive this can be avoided by only manually adding and saving info from the seed signer. Ps please respond to the comment from sangmachn regarding seedsigner + password keeper type unit. I would also like to know if this can be done for an all in one account security unit.

Thanks :)
Thanks a lot for your awesome content! You are a key aggregator and enrichment for the topic on UA-cam!
Thanks and thanks for the tip. :)
oh wow, this is great. Having the ability to load the applets onto blank cards straight from the seedsigner is pretty clutch. Great video.
I really think it deals with some of the major shortcomings with SeedSigner, still have some improvements to make as well :)

Love the integration with seedsigner!! Thanks!!
No worries, glad it helped

It probably can but will be a bit more work than implementing in Seedsigner. (I plan to look at Krux next for this)
Another great video. Thank you!

Seedkeeper can store other passwords as well, not just seeds :)
Would it be possible to flash PI-TREZOR with this set up? (Hope it’s not a stupid question 😅)
My fork of piTrezor with support for the waveshare display hat works fine. (Though the NFC reader won't do anything when running piTrezor)

You will need to reset the card, is it a DIY or a retail card?
My signer doesn’t have the reader option
Yea the official builds don't support it, you that's why I made a custom one and also run through the hardware that you need to pair it with.
can you explain how to reset a SEEDKEEPER by satochip when wrong password has been entered too many times, it says PUK code is required?
Your best bet is to use the Satochip tools utility here github.com/Toporin/Satochip-Utils
It also includes the ability to perform a factory reset :)
Specifically you want the release that you can download here github.com/Toporin/Satochip-Utils/releases
@@CryptoGuide yes worked, reset satochip seedkeeper, thanks for the information
Good job sorting it out :)
Is the ACM1252U-Z2 nfc reader even compatible for this project?
Probably, you can give it a go and report back :)
Is this seedkeeper support is already in SeedSigner main code?
No, only in my fork at the moment
Can a generic NFC reader be connected to seedsigner over USB?
If it's a NFC smart card reader then yes, but some generic ones will just be an RFID reader only
@@CryptoGuide so basically you can store seeds on a satochip and then gaplessly sign with seedsigner? Is there any difference between the satochip en the blank satochip they sell?
That's right. Basically the retail cards and the blank ones they sell are the same hardware.
where do i find the 3D printfiles?
Ah, I thought I had added it to the description, but had not. You can find them here www.printables.com/model/687553-seedsigner-openpill-pn532
Will this work if I send to a metamask wallet address from my Monacoin miner?
Seedsigner is only for Bitcoin

It's pretty great :)
This effectively defeats the purpose of complete network airgapping security
Howso? (Be specific)
This is not necessarily true if you only used the chip with the signer and entered all of the info manually, and never use that chip with any other non air gapped unit.
