When an agent pays for something with x402, a facilitator moves the money.
Researchers tested fifteen of them against x402's own rulebook, across 119 million payments from 2025.
All fifteen broke at least one rule. The teams were notified and fixes have shipped.
They could count every one of those payments because the chain is public. RobotMoney is building where the problems get published, not where they get handled behind closed doors.
