Verification & conformance
Checking things: validation, verification, compliance checks, attestations. That is what the sellers below say they do — the category is an organizational claim, assigned from each listing's own text by a published rule unless the seller registered their own. We verify revenue, not capabilities: find by claim, trust by evidence.

Ordering is method-only: verified tier first, then verified 30-day revenue, highest first (rows without verified revenue last), then listing id. No relevance scoring exists, and registration adds data, never rank.
- Sum of USDC transfers on the Base network to the seller address over the 30 calendar days ending 2026-10-13, excluding flagged exchange/fan-out senders and self-transfers. Revenue is attributed per seller address, not per listing. Methodology: verified revenue
