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.

Sending wallets · observed counterparties

No sending wallet addresses have been retained for this service. Buyer wallets are unknown; daily totals and reported payer counts do not reveal their addresses.

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.
