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
Multisig users already running MetaMask or Rabby give up nothing by choosing a QR-only signer that ships without a wallet app. Keystone is also the only record here selling a stainless-steel seed backup as a product in its own right.
