Coldcard just lost its users $38 million to a bug in the seed generator.
Blockstream Jade has never had a single reported compromise.
That is not luck. That is design.
Coldcard rewrote its crypto code behind closed doors for licensing reasons. Jade publishes everything - schematics, firmware, bootloader - so the whole world can check.
One wallet hides its math. The other invites inspection.
If you were a Coldcard user, you know exactly which one you want next.
