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.

Money, and what it actually proves

Exclusive
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 $0.139 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.
