Keystone 3 Pro

Overview

The Keystone 3 Pro is a feature-packed air-gapped hardware wallet that delivers a big touchscreen, a fingerprint sensor, and QR-based signing at a price well below the touchscreen flagships. Made by Keystone, it's fully air-gapped by design — no USB data, no Bluetooth — passing transactions to and from your phone or computer purely via QR codes and microSD. For buyers who want a large, modern, air-gapped device with multi-coin support, it's one of the best value picks.

It takes a security-forward hardware approach: three separate secure element chips work together, and the fingerprint sensor adds a convenient unlock layer on top of your PIN. The firmware is open-source, and Keystone supports Bitcoin plus a wide range of other coins, pairing with wallets like its own app, Sparrow, and MetaMask. The generous touchscreen makes verifying addresses and navigating multisig setups notably comfortable.

Honest trade-offs: some earlier Keystone discussion centered on whether every component was fully open (the company has moved toward more openness over generations, so verify the current state matters to you), and biometrics are a convenience feature, not a replacement for your PIN and seed security. As a QR-only device it also can't do USB signing if a given wallet only supports cable. But for a buyer who wants an air-gapped touchscreen multi-coin wallet with strong hardware and a friendly interface without paying flagship prices, the Keystone 3 Pro is a compelling, well-rounded option.
