"The most secure hardware wallet on the market."

That is what Coldcard called itself. Its users lost $38 million anyway.

The bug was in the ONE thing that matters: randomness. And it shipped for FIVE YEARS before anyone caught it.

Your hardware wallet is not secure. It is a black box with a company logo on it.

Unless it is open source.

Blockstream Jade is the only major hardware wallet that is fully open source. You can verify the code, the firmware, the bootloader. No blind trust required.

If a wallet cannot be audited, it cannot be trusted. After $38 million, that is not paranoia. It is math.

Being open source didn't really help that much, did it? Trying to plug Jade in this situation solely because it is open source is a bit ironic.
