What this measures
Verified volume for one closed Monday–Sunday UTC week grouped by capability-v1 category: each tracked seller address's verified payments are attributed to the categories of its live listings — auto-assigned from the listing's own text by the published rule, or the category the seller registered — and the top eight categories print with their payments and seller counts. A category is a claim about seller-asserted text, never our endorsement of what the seller does.
Disclosure that matters: a seller listed in several categories counts in each of them (the frozen v_category_market convention), so the category sums exceed the deduped verified total for the week — both are printed in the answer. Sellers that were paid but have no live listing appear as “(no active listing)”. The prior week's leader and its per-category figures sit in the table for comparison.
Reading this number honestly
Scope. This is a tracked-catalog figure: USDC received on Base by the seller addresses our x402 Bazaar-derived catalog tracks — never “the x402 market,” never “the agent economy’s volume.” Wallets can receive USDC for reasons unrelated to x402 sales; the method removes only known exchange, fan-out, and self flows.
What “verified” means here. “Verified” is the payment-level predicate of score-v1.0.0: a payment at or above the dust floor of $0.01 , sender not flagged exchange, fan-out, or self, not a self-transfer. It is not the seller-level “verified tier” on the rankings; the two labels are never conflated. Methodology: verified revenue
Dust. Payments below the floor are counted and summed separately and shown beside verified — never netted out, never labeled verified. The dust figures for the same week are on How much x402 traffic is dust?
- Every USDC transfer on Base to a tracked catalog address in the window, passed through the score-v1.0.0 verified predicate (at or above the dust floor, sender not flagged exchange/fan-out/self, not a self-transfer). Recomputed weekly from the warehouse by the frozen method; buyer flags at version flags-2026-10-13. Methodology: verified revenue
- The prior week is the closed Monday–Sunday UTC week immediately before, by the same method and the same flags version. Comparisons print as daily rates where the quantity sums over days; distinct counts compare window to window (both seven days). A future flags bump can revise past weeks, visibly — rows are append-only.
- Category figures follow the frozen v_category_market convention: a seller listed in several capability-v1 categories counts in each of them, so category sums exceed the deduped total — disclosed wherever category figures print. Sellers with no active listing appear as “(no active listing)”. Methodology: capability categories
- Coverage at compute: all seven window days coverage-published at coverage_ratio 1.00; the window recompute reconciles to the micro with the published v_market_daily weekly sum. On-chain record observed through block 52,544,868 (2026-10-13T08:11:23.000Z); window blocks 52,184,527–52,486,926; chain-sync last success 2026-10-13T08:21:07.381Z; 2,088 tracked seller addresses, 1,292 of 1,292 tier-A complete.
