Had a look at the @Keycard_ Shell. Great option to split hardware in such a way as to remove vendor trust. (Works great with DIY flashed Javacard) youtu.be/5NPP4c0D2FM Core functionally of my @SeedSigner fork (Shieldsigner) but available to normal folk as a retail offering :)

That sir is a “ShieldSigner”.

Now the new seedsigner battery smartcard is here, we’re expecting a bit more development on the shieldsigner fork to become official and to ease the flow even more for noobs. In the end, 99% only needs a single sig with a passphrase. If you want to order you can find it via the link in the next post.

Custom request from a client 👀 Beautiful transparent green #SeedSigner / #shieldsigner with smartcard interfaces, battery powered 🔋 Fully air-gapped. No cables. No compromises!

New update on the NFC model for #Shieldsigner, the unofficial fork from #seedsigner

Extra update on NFC capabilities for #ShieldSigner (unofficial #SeedSigner fork) As requested, applet installation over NFC is now tested, and it works perfectly. Slightly slower than contact or USB, but fully functional 💪

Making solid progress on NFC integration for #ShieldSigner (unofficial #SeedSigner fork) This unit features built-in NFC in the enclosure, allowing NFC cards & rings for keys import without a physical card inserted More updates soon!
