Keystone, which rebranded from Cobo Vault in June 2021, has been producing cryptocurrency wallets since February 2018. The company first launched a bitcoin-only firmware in 2020 and has now released a comprehensive version of the firmware after taking into account feedback from its customers.
“Since day one, we have been closely listening to the Bitcoin community and doing our best to develop the most secure hardware wallet,” Keystone CEO Lixin Liu told Bitcoin Magazine.
“After receiving feedback from the community, we rewrote our embedded system using Rust, which is often considered the least bug-prone, and open sourced every line of code, allowing users to inspect and verify the integrity of the firmware at any time,” he added.
The new firmware also supports security-oriented features such as the Shamir Backup application and the import of three different seed phrases.
Not only is the new firmware more secure, but the Keystone 3 Pro itself was also designed with security in mind. The device is air-sealed, has three Secure Element chips and comes with a built-in self-destruct mechanism that erases all stored private keys if it detects physical tampering. It also enables users to create a seed phrase without having to pair it with any native software first, eliminating the potential risk of private key extraction through software.
“In addition to security upgrades, we focused on improving ease of use,” Liu told Bitcoin Magazine.
Liu highlighted how the firmware works seamlessly with Blue Wallet, Sparrow Wallet, and Nunchuck as well as how the Keystone 3 Pro has a 4-inch color touchscreen and a fingerprint scanner, making logging into the device more convenient. He also noted that the device's battery life is more than 20 times greater than that of its predecessor.
The Keystone 3 Pro currently retails for $129 on the company's website, Amazon and Newegg.
“We have kept our product affordable without compromising on product quality, user experience and security,” Liu added.
