Disclosures
What a Confidence Report is, and is not
A Confidence Report is evidence that specific checks passed on a specific date, on specific hardware. It is not a guarantee of recovery, not proof of reserves, and not a substitute for testing your own backup.
Bitcoin Witness makes verification software for generic hardware the user purchases himself. We never hold keys, coins or custody, and nothing on this site is financial, tax or legal advice.
Ship dates are estimates and may move.
