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.

Receiving wallets · provider payment addresses

All published receiving wallet addresses for Base64.

solana E98BQ1vEztvN7TV9SZEti6eQK2j3opmawMxQmTuTY3ZN Shared address · activity cannot be assigned to this serviceFrom source record · source: payai

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.

solana exact 0.005 USDC

“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 5000 = 0.005 USDC per call on solana.

Opportunity insights

2 findings from measured data
  • Priced, but nothing observed arriving

    A price is published, yet no transfer reached the payout address in the last 30 days. Either the buyers pay elsewhere, the volume is below one cent, or the endpoint is dormant. Only 27 of 3156 services in this category have attributable inflows at all.

Money, and what it actually proves

Verified revenue · 30d Unknown
Observed inflows · 30d —
Attribution Unscanned
Receipt ledger Not connected

Rail not scanned · confidence low
The rail is not an EVM address, and our transfer scan currently covers USDC on Base only.

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 nothing measurable: no price, no attributable address, no receipt. The rail is not an EVM address, and our transfer scan currently covers USDC on Base only.

From source record

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it.

Provenance

One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
