x402 Protocol Processes $15M in Transactions, Signaling AI Micro-Payment Growth

Visa and Artemis report x402 handled $15M across 109.6M transactions on Base, Solana, and Polygon, marking a shift toward viable AI agent micro-payments.

Woofun AI reports that Visa and Artemis published the "Agentic Payments from the Ground Up" report, distinguishing between macro transactions and micro payments for AI agents. The analysis highlights x402, which processed $15 million across 109.6 million transactions by April 21, 2026, primarily on Base, Solana, and Polygon using USDC. In contrast, the MPP protocol recorded $25,000 in volume within 33 days of its March 2026 launch. The report attributes this growth to advanced AI capabilities and lower blockchain settlement costs, though trust and liability challenges remain.
