Keystone 3 Pro vs Trezor Safe 5
Connected versus air-gapped. The Safe 5 plugs in via USB — a vetted, standard path; the Keystone never touches your computer at all, signing transactions by QR code with three secure elements watching. Air-gapping removes an entire class of attack at the cost of a chunkier workflow. For most people USB is fine; for the threat-model-minded, the gap is the feature.

FAQ
Which is more secure, Keystone 3 Pro or Trezor Safe 5?
Both keep private keys off your internet-connected devices, which is the security property that matters most. The differences above — secure-element certification, open-source firmware, air-gapping — are about which residual risks each design chooses to eliminate. For nearly everyone, either beats any software-only setup.
Where should I buy whichever I choose?
Only from the manufacturer or an authorised retailer — never marketplace resellers, where tampered devices are a documented attack. Our individual reviews link the official stores.
Do I still need an exchange account?
Yes — wallets store crypto; they don't convert Australian dollars. The usual flow is buying on an AUSTRAC-registered exchange, then withdrawing to your wallet. Our migration checklist covers doing that safely, test transaction included.
