Payers on a day can be counted more than once if they paid through more than one facilitator.

The page link uses the service's site when we have one, and the payee address otherwise.
Volume and payment counts include earlier days. Transaction-level detail available from arc from October 26, 2026, base from October 23, 2026, polygon from October 27, 2026, solana from April 12, 2026, tempo from June 22, 2026.
