Privacy
Effective 20 October 2026
proof.bsvkey.com is run by Embryo Space Inc., doing business as BSVKey ("we"). It re-checks BSVKey's Bitcoin BSV transactions in your browser. The short version: no accounts, no forms, no cookies and no analytics, and our servers take no part in the checks.
WhatsOnChain
To check a transaction, your browser downloads it and its block header straight from WhatsOnChain (api.whatsonchain.com), a public Bitcoin BSV explorer. WhatsOnChain sees your IP address and which transactions are looked up, including any transaction ID you type into Check a txid. That is covered by WhatsOnChain's own policy.
Stored on your device
Only your light or dark choice, in this browser's local storage (proofwall_theme). No cookies.
