Keystone, a leading crypto wallet company, has recently unveiled its latest innovation – a bitcoin-only firmware for its advanced device, the Keystone 3 Pro. This new firmware release comes with a host of exciting features, including support for Blue, Sparrow, and Nunchuk, Taproot support through Sparrow, XPUB QR code display, Bitcoin Testnet support, passphrase support, and Shamir Backup support.
The company, formerly known as Cobo Vault, has been in the business of producing crypto wallets since 2018. After receiving feedback from the Bitcoin community, Keystone decided to revamp its firmware, rewriting it using Rust, an open-source programming language known for its security features. The new firmware is not only more secure but also more user-friendly, with added features like Shamir Backup implementation and support for importing three different seed phrases.
In addition to the firmware upgrades, the Keystone 3 Pro device itself boasts top-notch security features, including air-gapped technology, three Secure Element chips, and a self-destruct mechanism that erases all private keys in case of tampering. The device also offers a 4-inch color touchscreen, a fingerprint scanner for easy access, and an impressive battery life that is over 20 times greater than its predecessor.
Despite the advanced features, the Keystone 3 Pro remains affordable, retailing for $129 on the company’s website, Amazon, and Newegg. Keystone CEO Lixin Liu emphasized the company’s commitment to providing a high-quality product without compromising on security or user experience.
Overall, the release of the bitcoin-only firmware for the Keystone 3 Pro marks a significant milestone for the company and the Bitcoin community. With its enhanced security features and user-friendly design, the Keystone 3 Pro is sure to be a popular choice among crypto enthusiasts.
