There is no traditional data transfer mechanism on our Bitcoin only devices, and in turn no way to update firmware. This is by design :) The device is used to sign PSBTs in a 100% air-gapped manner. It accepts PSBT's as valid inputs, signs them, and produces QR codes of the signed transaction (after you confirm details) ready to be broadcasted. Being non-upgradable also reduces the risks against malicious firmware attacks (Dark Skippy etc). Even if the Bitcoin blockchain does a hard fork, older Cardware devices will still be able to sign PSBT's as signing (BTC UTXO's) is specific to the receiving address (eg Segwit address gets Segwit signing, Taproot address gets Taproot signing). In other words there is never a scenario where a device stops being able to sign PSBTs. This does however pose a slightly higher risk for EVM based assets/chains, as such we are working on including the mechanism to update your firmware in an air-gapped manner with our BTC/EVM version. On many hardware wallets, updates to software on an internet-connected companion device (such as Ledger Live) can require firmware updates on the wallet itself due to the two-way communication between the devices. With our devices, however, that isn’t necessary. We can upgrade the web wallet—which functions in a watch-only mode—without needing to change the hardware code, as long as the data sent to the device follows the expected format (using PSBT for Bitcoin and Smart Contract data packages for EVM).

Why We Chose USB: Power Without Risk The USB-C port on Cardware Wallet is strictly for power transfer. There is no data transmission capability, ensuring that no data can be exposed or transmitted during operation. You can power the device through a USB connection to a computer, wall outlet, or power bank without any risk of compromising its air-gapped nature. This feature ensures that the device remains offline and secure at all times. Keep your private keys private with Cardware Wallet. Order yours today:

Why We Built Our Transparent Casing The transparent casing of Cardware Wallet is not just about standing out visually, it’s a fundamental part of its security architecture. When designing a hardware wallet, trust is non-negotiable. Users need to be certain that the device they hold in their hands hasn’t been tampered with or modified. This is where the transparent casing comes into play. Physical Inspection for Additional Security By allowing users to physically inspect the internal components, Cardware removes the mystery often associated with enclosed devices. You can see exactly what’s inside, ensuring that the wallet hasn’t been opened, altered, or compromised. Unlike other designs where potential tampering could go unnoticed, Cardware’s transparency is a safeguard against hidden modifications. Verifiable Trust This design reinforces verifiable trust, what you see is exactly what you get, with no surprises. For users who value security and self-custody, this design drives the principle of don’t trust, verify. Alignment with our Open-Source Principles Beyond physical inspections, this approach also aligns with Cardware’s open-source ethos, encouraging both community trust and ongoing user scrutiny. With the transparent casing, accountability isn’t just promised, it’s built directly into the product. See security you can trust. Cardware Wallet’s transparent design means no hidden risks, just complete accountability. Order yours now:
