USDC payments: 20

Counted by addrbook from USDC transfers to the wallets it asks to be paid at, on Arc. A payer is independent when it is not one of the seller's own wallets and the seller did not fund it; the largest payer made 80% of the payments. Counted 9 Nov 2026, 14:22 UTC. How payers are counted

different wallets paid it, last 30 days: 2
paid calls, last 30 days: 2
last paid call (UTC): 7 Nov, 00:06

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 8 Nov 2026, 20:45 UTC. addrbook has not counted these payments itself.
