Blockchain wallets

Full addresses · public payment evidence

Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.
