📰 Key Highlights

A joint report by Visa and blockchain data platform Artemis points to concrete signals of machine-to-machine (machine-native) micropayment adoption, with the x402 payment protocol developed by Coinbase as a representative case. Since launching in May 2025, x402 has processed approximately $15 million in adjusted transaction volume, with adjusted transaction count exceeding 109 million. The protocol saw a clear acceleration in October 2025: monthly transaction count jumped from 40,000 to 3.8 million, bringing that month’s processed volume to 38 million transactions — a notably significant surge.

The report argues that the future of machine payments isn’t a competition between stablecoins and traditional card networks, but rather convergence: card payments continue to handle proxy purchases within existing merchant networks, while stablecoins serve machine-native micropayment scenarios — and the two may even be combined within the same workflow. The report also mentions that Stripe-backed Tempo’s Machine Payment Protocol (MPP) already covers both on-chain crypto payments and fiat payments processed via shared payment tokens. Visa, meanwhile, says its Card Specification SDK is designed to extend existing card payment protocols to card-based AI agent commerce.

Notably, Visa’s crypto division and Tempo both launched AI tools simultaneously in March 2026: Visa’s tool enables AI agents to execute same-day payments, while Tempo unveiled its Machine Payments Protocol the same month, aiming to make payment flows between AI actors more seamless.

💬 JudyAI Lab Take

The joint report from Visa and blockchain data platform Artemis shows concrete signals of machine-to-machine micropayments: taking Coinbase’s x402 protocol as an example, cumulative adjusted transaction volume has reached $15 million since launch, with monthly transactions exploding from 40,000 to 3.8 million in October 2026.

The report highlights a design philosophy worth noting: the future of machine payments isn’t stablecoins replacing card networks — it’s the two coexisting in complementary roles. Card payments extend existing merchant networks for proxy-style purchases; stablecoins handle high-frequency machine-native micropayments, and the two may even show up within the same workflow. Visa and Tempo both launched AI agent payment tools simultaneously in March 2026, showing mainstream payment players are actively staking their claim.

For builders building AI agents, now is a good time to evaluate “how should agents pay?”
