Your hardware wallet's security is only as good as its last firmware update.

No updates? No fixes. Dead project? Dead security. Black box? You will never know what changed.

Coldcard shipped the entropy bug in a "security update." The update was the problem.

With open source firmware you can see exactly what each update does before you install it.

Blockstream Jade. Every byte of firmware public. Every change auditable.

Never install blind again.
