Keystone Review: Features, Pricing & Integrations 2026
Rated 4.3/5, Keystone's 4-inch screen and QR-code air-gap offer top security from $49, though signing transactions takes more steps than USB.
Expert Analysis of Keystone
Keystone works well when you want to sign transactions securely using an air-gapped QR-code workflow and a large touchscreen. The friction starts when you try to manage assets natively, as the companion app supports only a few cryptocurrencies, forcing you to connect to third-party software like MetaMask for broader asset coverage. Before buying, compare vs Ledger Nano X, which offers broader native asset support directly within its proprietary Ledger Live application.
