# NGRAVE > The most secure wallet ever built. NGRAVE helps users secure and manage digital assets with an offline hardware wallet, a stainless steel key backup, and a companion mobile app for QR-based transactions. NGRAVE helps users protect and control crypto by keeping private keys offline and enabling QR-based signing. The hardware wallet is fully air‑gapped, while the metal backup lets users store a recoverable copy of their key offline. With the mobile app, users view balances, receive funds, and create transactions that are signed on the device without network connections. The offering targets self‑custody users who want strong device isolation and a durable recovery method. - Type: Company - Sector: Custody and Wallets - Status: Active - Founded: 2018-01-01 - Profile: https://thegrid.id/profiles/ngrave ## Products - [NGRAVE ZERO](https://thegrid.id/profiles/ngrave): NGRAVE ZERO is an air‑gapped hardware wallet that keeps private keys offline and signs transactions via QR codes.

(Hardware Wallet, Live, Main Product) - [NGRAVE GRAPHENE](https://thegrid.id/profiles/ngrave): NGRAVE GRAPHENE is a stainless steel seed backup that encrypts the key using two plates so it remains unreadable unless combined.
