James O'Beirne joins Marty to break down the critical Coldcard RNG vulnerability affecting devices produced after 2021. They discuss how insufficient entropy generation exposes private keys, why MK2, MK3, MK4, and Q users must migrate funds immediately, and how AI models accelerated the discovery. The conversation covers multisig risks, passphrase limitations, dice roll safety, and the broader collapse of trust in single-vendor hardware wallets. Essential listening for Bitcoin self-custody security.
