Why NGRAVE costs more
NGRAVE is engineered for high-net-worth crypto holders and family-office custody. The Zero device is fully air-gapped — no USB, no Bluetooth, no NFC. Communication with the NGRAVE Liquid app happens only via QR codes. The secure element on the Zero is EAL7-certified — the highest available certification for consumer hardware, a step above the EAL6+ used in Ledger devices.
The companion product, NGRAVE Graphene, is a folded stainless-steel seed backup designed to survive fire, water immersion, electrical surge and structural collapse. The Graphene is one of the most thorough metal backups on the market.
When NGRAVE makes sense (and when it doesn't)
For a user holding $50,000+ in crypto as a long-term store-of-value, NGRAVE's premium positioning is defensible — the incremental cost over a Ledger Stax or Trezor Safe 7 is small relative to the assets being protected. For a user holding $1,000–$5,000 in crypto who also wants to interact with DeFi and NFTs, NGRAVE is overkill: the air-gapped UX is slower than wired alternatives, and the smaller ecosystem means more friction when interacting with cutting-edge dApps.
Look for the Black Friday and Christmas sales
NGRAVE's most generous discounts hit during Black Friday and the Christmas/New Year window. Expect €50 off the Zero plus bundle deals on Graphene + Zero packages. Newsletter subscribers often get advance access to flash sales.
NGRAVE vs Ledger Stax vs Trezor Safe 7
All three target the premium tier. NGRAVE leads on certification level (EAL7 vs EAL6+ for Ledger) and air-gapped purity. Ledger leads on ecosystem and developer support. Trezor leads on firmware openness. For pure cold-storage maximalists, NGRAVE wins. For day-to-day DeFi use, Ledger Stax or Flex is more practical.
Frequently asked questions about NGRAVE
Is NGRAVE worth the higher price?
For long-term cold storage of significant balances (typically $50,000+), the premium is justified by the higher certification level and fully air-gapped architecture. For active DeFi users with smaller balances, a Ledger or Trezor is more practical.
What is EAL7 vs EAL6+?
Common Criteria security certification levels. EAL6+ (Ledger's secure element) is already strong. EAL7 (NGRAVE's secure element) is the highest level — used in military and defence applications. The difference is marginal for ordinary threat models but meaningful for high-value targets.
Can NGRAVE Zero connect to MetaMask?
Indirectly via QR-code signing through the NGRAVE Liquid app, which supports WalletConnect bridges. Slower than Ledger's native MetaMask integration but workable for occasional DeFi transactions.
