The GridPlus Lattice1 is a desk-based hardware wallet with a large 5-inch touchscreen and WiFi connectivity. It is unique among hardware wallets for its card-based key management — it uses removable SafeCards that store private keys on secure elements. The Lattice1 can store multiple sets of keys, display full transaction details on its large screen, and supports Ethereum, ERC-20 tokens, and EVM-compatible chains. Firmware is open-source.
