COLDCARD vulnerability what happened, and what to do
Informational only, and this site never asks for your recovery words. details

Informational only. This is independent analysis and an evidence-backed explainer, not financial, security or legal advice, and not a substitute for professional advice about your own situation. It is not affiliated with, endorsed by, or speaking for Coinkite, Block, or any other party named here. Published estimates are attributed, and differing scenarios are kept separate with their assumptions. Act on your own judgement. Editorial standards and corrections.

Do not disclose recovery material to a website, form, message or support account. This site never asks for it. Deliberate recovery on independently verified offline equipment is a separate operation. Seed-word safety.

How to check this yourself

Each copy above is identified by the SHA-256 of its extracted text, shown beside it, and the diffs are plain unified diffs. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
