Study Finds Majority of x402 AI Agent Payments Are Fictitious or Internal

Jul 15, 2026

A population-scale analysis of the x402 protocol for AI agent payments on the Base blockchain reveals that, over 280 days, 21.20% of 136.7 million settlements are fictitious and 63.78% are internal to linked clusters. The study finds that genuinely independent payments are much lower, ranging between $187,861 and $20.3 million, indicating that settlement counts primarily reflect manufacturability rather than real adoption.

Why it matters: This research challenges claims of a robust AI agent economy by demonstrating that most on-chain payments can be artificially generated, undermining settlement count as a metric for genuine autonomous economic activity.
