CZ Comments on "Coldcard Hacked, Loss Exceeds $71 Million": In self-custody mode, vulnerability patch cannot protect previously generated wallets

August 2nd. Regarding the "Coldcard Wallet Continues to Be Attacked, with Stolen BTC Value Now Exceeding $71 million," CZ stated in a post, "In self-custody mode, even if developers patch the vulnerability, they cannot fix previously generated wallets; for users using air-gapped devices, developers cannot directly reach out and alert them. Until users take proactive measures, the associated wallets may still remain exposed to attack risks."

CZ stated that he supports self-custody, but this also means that the security responsibility is solely on the user.
