Bitcoins in the form of banknotes?
So basically you're selling fancy paper wallets?
Some people say you shouldn't use them at all, but it's even worse if someone else creates them. Why would anyone trust you with their money?
To start: can you prove
this?
8. Swiss notary proof of integrity, authenticity, non-repudiation, and unicity
So, a special protocol for creating the cold wallets, erasing the cold wallets and destroying all hard drives after production exists at the printing company. Supervision by a Swiss notary and a Swiss IT security company, the printer’s 27001 security risk compliance team and SMD security team furnishes proof that files used in the printer are deleted after production. At the end of the process unicity proof is performed and there is absolutely no possible means of replicating it.
It's hard to check any of these claims remotely. Why don't you mention which notary and IT company you used? How many hard drives (plural) do you use for this?
This is a weird way of testing:
10. Private key and wallet address quality checks per batch
Our company’s quality check tests the first (A) and the last (B) Icynote of every batch and two random Icynotes (C, D) as follows. We send a small amount of cryptocurrency to A, then from A to B, then from B to C, then from C to D, and then from D to the original source. If this passes the test, it implies that the batch and each individual Icynote are printed correctly.
You only need to verify the address created from the private key, there's no need for a "chain" of transactions. But since you say you did this, maybe you can show photographs of a set of Icenotes A, B, C and D, so we can verify those transactions happened on-chain (before today). Even better if you sign a message from all involved addresses.
