The Keystone Pro (previously known as Cobo Vault Pro) is a cryptocurrency hardware wallet that is completely air-gapped and comes with a four-inch touchscreen, open-source firmware with a fingerprint sensor, and PSBT Bitcoin multisig support to additional security from malicious attacks.
Keystone is a hierarchical deterministic HD hardware wallet that is BIP 32/39/44 compliant. By integrating QR codes to sign transactions, Keystone has decreased the risk of malware intrusion and enhanced visibility. Due to this feature, the Keystone Pro is completely air-gapped.
The Keystone Pro’s wallet batteries are detachable to avoid corrosion, and both the Essential and Pro versions are AAA battery compatible, so you won’t have to worry about battery failure at all. Keystone Pro also comes with a rechargeable battery.
Note: The Keystone Pro hardware wallet is completely air-gapped which means that connecting to blockchain networks necessitates the use of additional software.
