WalletScrutiny hasn't checked it out yet, but I hope with funding secured now, they will try it out. Otherwise we have to do it ourselves..
WalletScrutiny outreached us few weeks back and we have provided all the information they required. They should be releasing report at their end, soon.
Also, Keylabs recently conducted our wallet audit and their report can be found here
https://keylabs.io/cypherockCool, excited to read it! Thanks for the link. Any plans for open-sourcing hardware, too?
Keylabs is actually legit; I've seen their stuff about Ledger and they really know what they're doing. Having a positive audit by them does mean something.
Seems a bit expensive to me, too; when I can get an airgapped Bitcoin-only device with open-source hardware for 60 extra bucks.
The device is available at a discounted price of $100 for Black Friday sale. Updated the website and Code to remove any confusion. New Code: NOSEED75
$100 makes it more competitive, for sure!
My main complaint / critique with your concept of splitting the seed and having people store the cards in different location is, that it makes the everyday usage less convenient. This looks like a reasonably solid cold-storage setup for non-technical people, who could find it difficult to create and deploy a paper-based multisig setup.
But for me, a hardware wallet is a convenient, yet secure (from software & hardware attacks) way to spend Bitcoin any day, anywhere. Of course, a 'hardware wallet' setup which stores the seed in multiple distributed locations, will be more secure, but it will be much less convenient when trying to spend. I'd personally probably just use it in single-sig mode (if possible) or store all the cards together to be able to use it quickly; although that would kill its main selling point.
What I do not like at all is your shitcoin and centralized KYC exchange integration.
CySync app already supports 20 different payment methods through our partners onramper for you to directly buy Crypto in 15 different currencies directly on the app in case you already do not have Crypto.
Onramper does not save any KYC information. All user information is sent directly to the relevant partner that facilitates the transaction. As such, we cannot currently ensure that the same information and documentation can be re-used across various fiat onramps. We do have KYC re-use on our roadmap, but for later this year (Q3/Q4 2022).
KYC data is not even saved by you or your provider, but actually by
another service
behind 'onramper', so I don't even know if users get to know where their data ended up and who to contact if they want it deleted.
Your X1 cards which stores your Crypto is never Upgradable and remains Cold at all times.
Downside: someone discovers a hardware / firmware bug in the JavaCard and those cards will need to be replaced with new, secure cards, as there is no update mechanism to fix the issue (unlike Trezor and Ledger who fixed hardware attacks through firmware upgrades).
Cypherock decentralizes your private keys to give you 10x more security.
This is a little bit disingenuous..
Did you somehow multiply 2x5 (because of the 5 keys) to get to the conclusion that it's 10x safer? Safer than what? What's the benchmark? Throwing out a number like that to impress newbies is not very cool. You and I know that it's hard to quantify how much safer this setup will be, since you don't know how (well) people will deploy / store their 5 keys.
