Question 3

Keystone Hardware Wallet Feature Highlights

Accepted Answer

Articles on: Keystone Blogs Keystone Hardware Wallet is a 100% Air-gapped QR code communication hardware wallet for Bitcoin, Ethereum, tokens of EVM compatible chains, USDT, BCH, XRP, Tron, LTC, Dash, Polkadot, Kusama and 1000+ more cryptocurrencies.

It offers a convenient cold storage and blind signing solution with an open source firmware, 4 inch touchscreen and PSBT Bitcoin multisig support. Protect your cryptocurrency with the perfect balance between secure and convenient hardware wallet with mobile phone support.

These are the full feature highlights of the Keystone Essential and Pro.

All hardware wallets need some means of connecting to the network to sign transactions; how “air-gapped” your hardware wallet is depends on how it limits the attack surface when transmitting data to an internet-enabled device. QR codes have a smaller attack surface than USB, NFC, and Bluetooth, making them the perfect means of data transmission for an air-gapped hardware wallet. We have pioneered an animated QR code solution that enables transmission of larger amounts of transaction data and have also developed microSD card capability as requirements for compatibility with desktop wallets like Electrum and Wasabi are more demanding.

Using QR codes, you can verify each and every data transmission to ensure that information coming into the Keystone Hardware Wallet contains no trojans nor viruses and information going out doesn’t leak private keys

Question 4

Can I use a different brand of hardware wallet to recover my assets if my Keystone is lost or damaged?

Accepted Answer

Articles on: Keystone Hardware Wallet

Keystone requires users to have complete control and ownership of their private keys (recovery phrase). If the Keystone device is lost or damaged, the Secure Element will protect the private keys from being exposed. The Keystone Pro also has a self-destruct mechanism that automatically erases all information, including private keys, if the device is disassembled.

Different brands of hardware wallets use different derivation paths, so if you import the recovery phrase into a hardware wallet of a different brand, some of the assets on certain addresses may not be visible or accessible. If your Keystone is lost or broken, it is recommended to recover your assets using a wallet with the same derivation path as Keystone.

If you have any additional concerns, please contact the Keystone Support Team. Our administrators will assist you as soon as possible.

Question 6

Why is it necessary to update the firmware using a MicroSD card?

Accepted Answer

Articles on: Keystone Hardware Wallet

Executing firmware updates via a SD card is more secure because it reduces the risk of online attacks. The SD card is a physical device that is not connected to the internet, making it less vulnerable to hacking.

In contrast, methods such as Bluetooth rely on wireless communication and are more susceptible to interception or spoofing. Studies have also shown that hardware wallets which use SD cards for updates have a lower count of security breaches compared to those that use other methods.
