what's GridPlus?
GridPlus is a U.S.-based company specializing in secure hardware solutions for cryptocurrency management. Their flagship product, the Lattice1, is a touchscreen hardware wallet designed for seamless interaction with blockchain applications, supporting networks like Ethereum and Bitcoin via integrations such as MetaMask. It features a large 5-inch display for verifying transactions, miniaturized secure chips for protection against physical and digital threats, and compatibility with SafeCards—PIN-protected hardware modules that enable users to manage unlimited wallets and seed phrases without traditional paper backups. The Lattice1 emphasizes user-friendly self-custody, allowing instant wallet switching and separation of trading from long-term holdings. It runs on a custom Linux OS with open-source firmware commitments, incorporating anti-tampering measures like wire mesh enclosures. SafeCards store encrypted seed phrases, providing portable, secure backups. GridPlus focuses on making advanced crypto security accessible for everyday use, supporting multi-chain operations and eliminating the need for multiple devices.
