• Multi-Signature (Multisig) Support

Cardware Wallet integrates multi-signature (multisig) capabilities, allowing for the configuration of multi-signature wallets where multiple private keys are required to authorize a transaction. This functionality enhances security by distributing signing authority across multiple parties or devices, reducing the risk of unauthorised transactions. Multisig is particularly useful for institutional investors, collaborative funds, or joint account setups, providing a higher level of control and security.

• Hierarchical Deterministic (HD) Wallets

Cardware Wallet supports BIP-32/BIP-44 compliant hierarchical deterministic (HD) wallets, enabling users to derive a virtually unlimited number of private keys from a single master seed. This key derivation process uses a tree-like structure where child keys can be generated on-the-fly without requiring access to the master key, thereby enhancing both security and convenience. The use of HD wallets allows for improved privacy by generating a new address for each transaction while keeping the wallet structure organised under a single seed.

• Broad Cryptocurrency Compatibility

Cardware Wallet is designed to be compatible with a broad spectrum of cryptocurrencies, supporting various blockchain protocols such as Bitcoin (BTC), Ethereum (ETH), and ERC-20 tokens, and any EVM compatible chain. This compatibility is achieved through adherence to standard communication protocols and APIs, allowing users to manage diverse digital assets within a single hardware wallet environment. The device's firmware is optimised for efficient processing of transactions across different blockchain networks, ensuring reliable performance and security.

• QR Code-Based Transactions

All transactions conducted with Cardware Wallet utilise a QR code-based mechanism for secure communication. The device generates a QR code representing the transaction details, which can be scanned by a companion app to complete the transaction. This method keeps the private keys offline and isolated, significantly reducing the risk of exposure to malware or network-based attacks. The QR code system is entirely air-gapped, allowing for the safe transfer of transaction data between devices without the need for a direct connection.

• User Interface

The user interface of Cardware Wallet is designed for ease of use, featuring a straightforward menu-driven system navigated through physical buttons. The interface supports multilingual options and provides clear prompts during key operations such as transaction approval, seed phrase generation, and device configuration. The display offers high contrast and clarity, ensuring that transaction details are easily readable, even in low-light conditions. The user interface is built on a lightweight embedded operating system optimised for quick boot times and responsive interaction.

• Backup and Recovery Options

Cardware Wallet includes comprehensive backup and recovery features centered around the generation of a 24-word mnemonic seed phrase compliant with BIP-39 standards. This seed phrase is the root of all derived keys and can be used to fully restore the wallet in the event of device loss or failure. For enhanced durability, the wallet comes with a steel seed phrase sheet, which provides physical protection against environmental damage such as fire or water. Additionally, the wallet supports encrypted backups of the seed phrase, allowing for secure digital storage. Please protect your seed phrase at all costs!
