Keystone Hardware Wallet

Keystone is an open-source airgap hardware wallet that utilizes an embedded system. The device is equipped with three secure element chips to further enhance its sec. One of Keystone’s unique features is its ability to support multiple recovery seed phrases, reducing the need to purchase multiple hardware wallet devices. With the primary aim of maximizing security against potential threats, minimizing dependence, reducing human errors, and eliminating single points of failure, Keystone also places a strong emphasis on extensive interoperability. It is compatible with well-known software wallets such as MetaMask (both Extension and Mobile versions), as well as other premier software wallets like the OKX Web3 Wallet, Solflare, Rabby, and more.
