Provider site ↗ How sources are measured

Pre-sign safety verdict for an off-chain EIP-712 signature (EIP-2612, Permit2, EIP-3009). Decodes what it authorizes (spender, token, amount, deadline), checks domain-spoof, approval-hygiene and scam-blocklist, returns allow, warn or block plus a 0-100 risk. Risk indicators, not advice.

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 31 of 13807 services in this category have attributable inflows at all.

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. See evidence levels.

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.
