What is Keystone?
Keystone is a highly secure, air-gapped hardware wallet designed to manage cryptocurrencies and digital assets. Known for its advanced security features and user-friendly design, Keystone aims to provide a robust solution for both novice and experienced crypto users.
Keystone 3 Pro: The Keystone 3 Pro is the flagship model in the Keystone lineup, featuring a 4-inch touchscreen that enhances usability by providing an intuitive interface. This large display helps users meticulously review transaction details before approval, thereby preventing blind signing and reducing the risk of authorizing malicious transactions. The Keystone 3 Pro supports QR code transactions for a streamlined process of sending and receiving crypto. Additionally, it includes a USB port for connecting to software wallets like MetaMask and performing firmware updates.
Security Features: Keystone 3 Pro incorporates three distinct Secure Element chips (Microchip ATECC608B, Maxim DS28S60, and Maxim MAX32520), each playing a unique role in reinforcing the device's security. These chips provide a secure environment for recovery phrase storage and fingerprint data. The device also features a built-in fingerprint signature authentication, adding an extra layer of security and ensuring that only authorized users can access the wallet.
The Keystone 3 Pro supports up to three distinct recovery phrases, each secured by different passwords. This feature allows users to manage multiple crypto accounts from a single device and easily switch between wallets. In case of a physical attack, the device can be configured to reveal a decoy wallet instead of the primary one, keeping the majority of assets secure.
DeFi and dApp Support: Keystone integrates seamlessly with a variety of software wallets, including MetaMask, Rabby, and others, enhancing its compatibility with decentralized finance (DeFi) platforms. This integration allows users to participate in DeFi activities like yield farming, lending, and trading on decentralized exchanges (DEXs) securely, with the hardware wallet protecting their private keys.
Advanced Features: Keystone is built on open-source firmware and hardware, allowing the community to audit, validate, and contribute to its development. It also includes advanced features like multi-signature support, the ability to decode DeFi transactions, and support for SLIP-39 Shamir’s Secret Sharing scheme. The device also has a PCI-grade anti-tampering feature, which ensures that any physical tampering results in immediate data wipeout.
