Informational only. This is an open source collection of what others have published about the incident, together with an explanation of it. It is 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. Material is attributed and quoted as published; where sources disagree their scenarios are kept separate with their assumptions rather than reconciled into one answer. Everything is meant to be checked against the linked evidence rather than taken on trust. Act on your own judgement about a particular situation. Editorial standards and corrections.

Do not disclose recovery material to a website, form, message or support account. This site never asks for it, and contributions containing recovery words or private keys are not accepted.
