Cardware Wallet is a South African-developed, air-gapped hardware wallet that uses QR codes for all data transfer, with no Bluetooth, Wi-Fi or USB connection. It stores private keys on a tamper-resistant EAL6+ certified secure element with read-only firmware, and supports BIP39 24-word seeds, HD wallets and multisig, with a separate model for Ethereum and EVM chains. The card follows open-source principles, ships with a steel seed backup sheet and has a transparent casing for physical verification.
