Description
Keystone is a company that develops and sells open-source, air-gapped hardware wallets designed for secure cryptocurrency management. Their flagship product, the Keystone 3 Pro, features a 4-inch touchscreen, fingerprint verification, and the ability to manage up to three separate seed phrases on a single device. The company prioritizes security through complete offline operation (air-gapped) and transparency with fully open-source hardware and software, allowing users to verify the code. Keystone wallets integrate with an extensive ecosystem of over 35 software wallets, including major players like MetaMask, OKX Wallet, and Solflare, and support over 5,500 crypto assets. They also provide a specialized Bitcoin-only firmware to minimize the attack surface for users focused solely on BTC. Keystone aims to serve both beginners and advanced crypto users by offering a secure, yet user-friendly, solution for asset protection.
