Coldcard Vulnerability Leads to 1789 BTC Loss, 8865 Addresses Affected

This matters less as a single loss than as a signal about where custody risk actually sits: a hardware wallet, the tool users adopt precisely to avoid counterparty and exchange exposure, proved to be the point of failure. The affected base is unusually broad for a firmware-level flaw, which suggests the issue is structural rather than a one-off user error. The open question is whether this shifts how the market prices self-custody risk versus custodial alternatives, and how hardware vendors address disclosure and remediation going forward.
