Blockchain wallets
Full addresses · public payment evidenceReceiving 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.

Opportunity insights
2 findings from measured data-
Call count and inflow disagree
The observed inflow implies about 111 calls at list price; the source counted 44 (factor 3). Either the effective price differs from the list price, or part of the volume belongs to other payers on the same address. Do not read the inflow as this service's revenue.

Receipt ledger
Not connected
Observed transfers
· confidence medium
Token transfers reached this service's own payout address. A transfer is not a purchase, and shared, refunded or unrelated transfers cannot be excluded.
Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is $0.111 arriving at the payout address in 30 days — that is volume, and a lower bound: transfers can be refunds, treasury moves, or payments for something else entirely.
Cross-check. At the published price the observed inflow would cover about 111 calls; the source counted 44. Two independent measurements of the same question — they never match exactly, because the effective price differs per call size and the address can also receive unrelated transfers.
