"When you’re punching your seed into a TitanDot plate, don’t look at it on a screen. 🚫💻" Why? Do you mean that I shouldn’t open the seed on the screen even for a single moment? That’s difficult, because even when sending it to the printer it usually appears briefly. Or do you just mean I should avoid leaving it open for a longer period? If I print it, that introduces two additional attack surfaces into the process. One is the printer (which obviously must not be a network connected device, and obviously no one else should have access to it – though that wasn’t discussed here). The other is the printed paper (which must be securely destroyed at the end of the process, and that wasn’t mentioned here either). By contrast, I have to open the seed on the screen in any case, even if only for the duration of a print preview. So at that point, how much additional risk is there if I leave it open for a few minutes while I punch it into the TitanDot plate?

I worded it a bit ambiguously before — I’ve corrected it since. I wasn’t referring to printing the private key (that should of course never be entered into any device other than a hardware wallet), but to the punching guide. When using TitanDot, you punch the binary index of the seed words into the plate. For this, there’s a punching reference sheet. My advice is to print that guide (and verify on Github) and perform the punching in a place where you’re not surrounded by network-connected devices or cameras.

Like this:

For example, do not calculate the addition of binary numbers with your mobile phone calculator, but with a simple, traditional calculator. And of course, there should be no camera devices open nearby
