Keycard: Secure Crypto & Hardware Wallet
AI summary of the linked articleKeycard is a product page for an open-source, air-gapped hardware wallet system built around swappable smart cards, with the Keycard Shell as an optional signing device. The page says each Keycard holds its own mnemonic words and can be switched in seconds, and that Shell signs by showing a QR code to the computer without connecting to it. It states that firmware and card applets are MIT licensed, that the card's software is sealed and cannot be updated, and that the Keycard works with 15+ software wallets. A Keycard Shell bundle with two Keycards is listed at €129,00, down from €149,00. |

3 comments I have Keycards already for a couple of years; but somehow never use them, but guess the shell (which did exist previously, and I don’t have) and being able to use them w/ a regular wallet is a game changer. I’m going to have a fresh look.  timSubmitter Yeah it‘s interesting because it looks as if you can use them to store an encrypted seed phrase and since they anyways seem to be a bit more reliable than just eg a piece of paper I think the card holds your master key (so the private key). And that is protected I think with a pincode. Then you use the card with your phone built-in NFC reader to sign. But each time I think you also need to put in the pin. If you forget the pin you still need to keep the seed frase to restore the card. I have to look into it again. But there was something that didn’t work for me UI wise. Anyway now you can use it on desktop with like normal wallets is a game changer for sure. (It used to only work with Status on mobile, which it seems was in permanent beta 😅) I have to look into Status also maybe again. But I gave up a bit on them I’m afraid. |
