Citadel Vault Project Update 🛡️ Bill of Materials finalized ⚡️⚡️ On the project development front, we are making steady progress. The hardware Bill of Materials has officially passed its final review. From NFC to a contact Smartcard reader As part of this finalization, we decided to change the Vault Card reader from an external NFC reader to a contact Smartcard reader. Both hardware modules are manufactured by ACS and utilize the exact same driver. This ensures the Vault OS maintains full backward compatibility with the previously issued NFC readers. The new Smartcard reader provides a smoother and more foolproof user experience. It physically shrinks the security attack surface by completely eliminating wireless NFC communication. The device itself is also physically smaller. Both reader types operate exactly as intended, and you can simply unplug them the moment user authentication is complete using your 2 of 3 or 3 of 5 Vault Cards to unlock the Vault. #citadelvault #inheritance #security #generationalwealth

Fully air-gapped. Built inheritance-first, so your heirs can recover decades from now with no cloud and no trusted third party. More soon. 🧡 #Bitcoin #selfcustody #inheritance #citadelvault
