NGRAVE ZERO vs Titan 2.0: Certified Security or Value Air-Gap?
Both wallets sign fully air-gapped via QR codes with no USB data connection or Bluetooth. NGRAVE ZERO counters with the highest-certified OS in the category (EAL7) and a fingerprint sensor; the Titan 2.0 answers with a sealed metal body, much broader asset coverage, and a $229 lower price.
Choose NGRAVE ZERO if you want the highest independent security certification (EAL7) and fingerprint unlock, and you're willing to pay a premium for it — when it's back in stock.
Choose ELLIPAL Titan 2.0 if you want air-gapped signing with a rugged sealed body, 3x the asset coverage, and a much lower price today.
