Keycard Shell

Recently i learned that @Ledger removed (yep, completely working) apps from its store for "inactivity". this includes @ironfishcrypto and @HNS. The company is so stupid that dont get that their hardware have been used for RELIABLE long term storage. In addition to the recent problems with ugrades 2.6.1 I think its the last drop in credibility and trust of their products. However the deeper question arrise - how to design a better system without so annoying upgrades. In that sense i think @urbit and @nockchain appoarch are the most advances frozen (in the core) systems out there which are far superior to EVERYTHING that exist now. Thinking deeper on how we can improve on the ideas of behind tree based, stable combinatorial system i invented nox: cyber.page/cyber-nox/ its really good itteration on nock, however with cryptography, confluence (and something else) baked in. The spec is kinda frozen - because its really obvious. Nox is the compute kernel of superintelligence. In the comming months i will slowly unrevel details of its beauty.

Disassembled the @Keycard_ Shell to take a photo for the new @Logos_network zine to highlight how simple, minimalist, and thoughtful its design is. Reassembled it afterward and it works like a charm. By the way, I forgot to include one small detail in the photo. Can you spot what’s missing? P.S. Tinker responsibly. 🛠️

Finally another winner in the land of hardware wallets! Unboxing, first look at @Keycard_ Shell & quick compare with some others like it. - Fully open source (software & hardware, MIT) - Good build quality (better than @COLDCARDwallet Q) - Clear screen - Can work without a battery - Great & simple initial setup of PIN code, key generation & saving to a Keycard - Full visibility of seed phrase - No vendor specific app needed, widely compatible, connects smoothly with @bluewalletio and @nunchuk_io - Cheap! You can have a Keycard Shell which comes with 2 Keycards for €109 currently - extra cards only cost €25 - Airgapped: camera to scan transaction QR codes & clear signing on the screen - Verifying via a web interface (which is inherintly insecure) feels weird but it's better than nothing. It does run only signed firmware. - Immutable cards, the software on the cards is permanently locked. - The version you order from Keycard will come with anti-tamper seal (fwiw) - Works with seedQR! Instantly scans it and then you're able to load a seedQR onto a keycard, glorious! Just select "Scan QR" in the "add key pair" screen during setup. I will definitely be offering this in the Bitsaga webshop but for now you should just get these directly from Keycard & purely support them. I'm genuinely happy to see the card innovation finally done well. This is a WINNER. Infinitely better than @Tangem which is a completely closed ecosystem with blind signing. The setup process is also significantly smoother than @era_wallet. With ERA wallet you still have to install the firmware yourself which is a huge hassle (how can it not be, over NFC wtf). Keycard does come preloaded with firmware (which you can verify through a web UI) and that makes this super beginner-friendly. Keycard new smartcard form factor is still way ahead. Great work Keycard, this is what we need: innovation but OPEN, without any vendor lock in. I love the fact that I don't have to even consider downloading their Status wallet which seems like a shitcoincompatible thing. Doesn't start up without a card though, which can be confusing initially. This is going to be a top contender for wallet of the year in 2026 IMO. It makes multi-sig so much easier! Might not be for everyone though.
