What else would you like us to show?

We received our testers' feedback that the standard QWERTY layout slows input. So we updated to ABC, together with smarter suggestions and selective key activation

Replacing a tiny transistor on a Shell prototype board. And we are back in business.

.@Keycard_ sent me one of their @Logos_network branded keycards (1 of many). Excited to use it together with @Keycard_ Shell. Thank you @glgrau x.com/0x_r4bbit/stat…

Keycards are powerful crypto hardware, because they are affordable... Much more so than buying a couple of Ledgers

If you missed my talk at the @0xHolonym Townhall on how @Keycard_ tech can enable value exchange, grassroots governance, and decentralized ID issuance in fragile communities - here’s the recording, notes, and outcomes: holonym.notion.site/Townhall-7-Jul… (my part starts around minute 20)

Time for some flexing 👀 We have been busy testing the keypad silkscreen; to ensure low wear, so that you can enjoy Shell for a long time

New card design - yay or nay?

Days ago, I saw a new airgap wallet: The Keycard Shell. It seems pretty perfect to me. This is like the ChainSigner idea, but with a smartcard to hold and protect the private key. Because I always felt that having to scan your mnemonic each time was kind of dumb.

@keycard_ is more than a hardware wallet! It’s an open-source technology that can be built upon for identity and payments. We’re super glad to see initiatives like this pushing the needle where it matters 👇

Tomorrow at the @0xHolonym Townhall, I’ll present a concept built on open-source @Keycard_ tech to lower the barrier to decentralized value exchange, governance & identity focusing on fragile communities where it matters most. Join 👇 lu.ma/owmtdra1

The Keycard + Shell combo is quite powerful. Keycards are cheap signers in a battle-tested format. Second signers on a @safe, and tap to sign on @ethstatus And Shell transforms any Keycard into a full-featured hardware wallet. On the go, or at home.

I think Safe + @Keycard_ setups can be very powerful. Really keen especially on a 2oo3 setup for individuals: - 1 primary signer card - 1 backup card - 1 trusted co-signer In a regular flow users would interact only with the signer card and the co-signer would run checks and…

Absolutely! And the beauty of JavaCards is that, on top of being highly secure and cost-effective, they offer great flexibility and modularity. Depending on the user's security setup and preferences, they can be used with mobile apps via tap, or with an air-gapped hardware wallet…

Remember 2021? If you make a NFT of a real Diamond ... you better store it on an 100% open hardware wallet
