Not to rain on your parade, but why?
How often do you make seeds that you would need this, and what's wrong with a stamp set?
Playing with the https://seedhammer.com today.
I Absolutely love it so far.
It arrived a few days ago - was well packed.
Don’t worry, the Seed is the same one I used for a lot of SeedSigner SteelQR testing and posting on the other app. Just don’t use it😉
I need to start using the BACON seed🥓🥰

Nothing wrong with a stampset at all.
But for backing up multisig inkl the output descriptor of the wallet for recovery, this is much more practical.
Also I help with the design of a V2 SeedHammer and I want to integrate the technology into a device existing in my brain exclusively atm..🤙
If you own enough Bitcoin to require multi-sig you shouldn't be entering all of the private seeds into this machine.
This can be used by multiple people to stamp with. Even if you bought it for solo use it would save you a ton of time. I've spent hours stamping a single seed. This machine will stamp that in a fraction of time with no more than a few button presses of my actual time. It'll also stamp everything you need for multisig recovery which would take even more time if done by hand.
Pretty careless way to manage your seed.
How so? The device has no memory and you use your own seedsigner to manage it. If you didn't trust me then you could simply flash your own firmware to your own device and stamp from it.
Opens you up to a lot of attacks, and sets a bad precedent for how to manage keys.
Which attacks would you be vulnerable to? The code is open source for the stamper so you can review that before flashing. There's no memory to store anything. It has no networking to transmit out. I don't see the attack surface.
Because the more you pass seed information the more inherent the attacks. You should handle your seed as few times as possible.
I don't want stepper motors plotting out my seed. That's incredibly dumb.
Whether or not the device comes with memory installed doesn't matter.
There are very creative people out there.
