Here is the whole Coldcard story in one paragraph:
A hardware wallet rewrote its crypto code. The rewrite broke entropy. Users generated "secure" seeds for years. An attacker recomputed the keys. $38 million left 500 wallets. Nobody could have checked - unless the wallet was open source.
Here is the whole solution in one line:
Blockstream Jade. Open source. Air-gapped. Verifiable.
