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.

What the provider says

Daily market-regime context for trading agents: is the market risk-on or risk-off? One call returns today's issue: BTC trend filter (SMA20/50), trend scores for 9 altcoins, US equity regime (SPY vs SMA200, VIX term structure), SPY RSI(2) state and an MSTR BTC filter. Use it once a day before an agent sizes or gates trades. Rule-based, from PAPER research accounts, no track record, not advice. Issue 2026-10-28 (payload_sha256 83e2fe3e396d430883693aef550539aa0fda970779887376108eec8e4fbea184).

Money, and what it actually proves

Verified revenue · 30d Unknown

Observed inflows · 30d $0.30

Attribution 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 $0.30 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.
