- Will the seed be covered with some material or the stainless steel on which the seed is written on will be an open cover?
The seed is stamped on a 4mm steel plate. It is then covered by another steel plate (2mm thick). The 2 plates are bound with nickel binding posts. Once bound the seed is not visible. I'll include a metal box for transport/storage:
Naturally a question then arises: "what happens when someone steals my wallet?". I personally use and recommend a passphrase (the 25th word) and NOT STAMPING IT on the plate. However if you wish to stamp the passphrase there is place for it at the bottom of the plate (it should fit ~ 16 characters).
- Don't you think the seed would be just more readable and more prone to exposure when it's printed on a big metal?
I think the seed should be readable. It should be big enough (and deep enough) that when your house burns and the steel oxidizes/rusts on its outer layer (due to high temperature) or is covered with several tonnes of rubble the letters should still be readable.
- Are you self-funded or backed up by venture capitalists?
I'm self funded. I'm a programmer, I work with code but I'm also interested in metalworking.
