AI agents are about to start spending real money. Stripe, Visa, and Mastercard are already rolling out protocols so machines can transact directly. But the real thing holding back enterprise adoption of x402 and Stripe’s new Machine Payments Protocol (MPP) is the elephant in the room.... governance. AI agents won’t be trusted with budgets until we treat them like formal enterprise entities with the exact same rigor we apply to human employees, contractors, and service accounts. This is exactly why AI + blockchain is inevitable. Only blockchain delivers tamper-proof data tagging, perfect action attribution and immutable history the foundation for creating real insurance scores and verifiable risk ratings at scale. Without it, we’re just giving autonomous agents credit cards with zero accountability.
