Hello there,
As we all know, black swan events are the looming shadow over everything crypto and it wouldn't be the first time that a faulty random number generator led to the loss of funds. Using a hardware wallet is a good decision, but we have no real insight in the generation process of the passphrase needed and as far as I remember, at least Ledger has no manual inputs, like wigglin the mouse or what-have-you to increase entropy. Should they have a vulnerability in their RNG, a lot of peeps are sitting there with their pants down.
To mitigate this, I was thinking of taking the BIP32(that's the right BIP, right?) word list, a die, a pen and a piece of paper.
As a die, I would use one of those roleplaying game dice in a sensible denomination, like eight sides or something. I haven't come that far yet, because in practice, I have a big problem: The last one or two words are a checksum(dunno how many, honestly). So, I would either have to bruteforce the whole thing (four digit possibilities, "typing" on a Ledger Nano S – No, Sir.) or somehow find a way to find out the checksum with some calculations (on the cheapest solar-powered calculator possible). Typing anything of this inot a computer is a big no-no for obvious reasons.
My question is, is there something like this already out there? And if not, has anyone enough insight into the generation of the seed phrase to know how complicated/impossible for a mortal human being it would be to generate the needed checksum, i.e. is this a possible endeavor or completely bonkers BS?
I am aware of the Glacier protocol, but they are using dice only to create entropy. There is also the option to create a brainwallet-type like that, but that would include generating the pubkeys/addresses on a computer. i want something to put into a HW wallet.
