Visa and Artemis Publish First On-Chain Agentic Payments Data: x402 Has 109M Transactions and $15M Volume

Visa and blockchain analytics firm Artemis published a joint research report titled 'Agentic Payments from the Ground Up' on July 16, authored by Tim Conrad, Onchain Data Lead at Visa. It is the first authoritative dataset on live machine-native payment volume across protocols. The headline figures: x402 has processed 109.6 million transactions with roughly $15 million in adjusted volume since launching in May 2025, with most activity on Base, Solana, and Polygon. Average payment size is a fraction of a cent, confirming the micropayment thesis. Stripe's Machine Payments Protocol, built with Tempo and Visa contributions, has processed roughly 115,000 transactions settling about $25,000 since launching in mid-March 2026 — far smaller volume but a fraction of the age. The report frames two distinct categories of agentic commerce: macro commerce, where agents act as proxies for humans on consumer-sized purchases that fit existing card rails; and micro commerce, software-to-software payments for API calls and compute slices, typically well under a dollar, where traditional payment economics break down and stablecoin settlement on newer blockchains becomes practical. The report explicitly states that many real agent flows will use both rails within the same task — cards for macro authorization, stablecoins for micro settlement. The standards landscape covered includes x402, MPP, Visa Trusted Agent Protocol, Google Agent Payments Protocol, and Visa Intelligent Commerce. Trust, identity, and dispute resolution are flagged as the major unresolved infrastructure gaps.

Why it matters: Visa publishing on-chain data on agentic payments is a different category of signal than a launch announcement. It means Visa's payments intelligence division is actively monitoring protocol-level transaction flows and treating machine-native volume as a metric worth tracking alongside card volume. The x402 figures — 109.6 million transactions at sub-cent average values — confirm the micropayment use case is real and scaling, not a developer demo. The MPP comparison is instructive: at 115,000 transactions in four months versus 109.6 million in fourteen, x402 has dramatically more volume, but MPP's multi-rail design and Stripe distribution give it a different adoption vector. The report's macro/micro framework is the clearest articulation yet of how card rails and stablecoin rails coexist rather than compete — which matters for builders deciding which infrastructure to prioritize.
