Why collective governance matters: Rain cites a McKinsey projection of $3 trillion–$5 trillion in worldwide agentic commerce by 2030. If agents will conduct both consumer purchases and machine-to-machine micropayments—for compute, API calls, and data—the ecosystem needs interoperable ways to establish identity, prove a user’s mandate, scope spending permissions, allocate liability, and share fraud signals. Fragmented protocols could otherwise slow adoption or create exploitable gaps.

Visa and Mastercard’s role: Mastercard’s Agent Pay for Machines is a related execution-layer initiative: it is designed to enable automated, including very small, transfers among AI agents and connected systems. Visa is likewise pursuing agentic-payment capabilities. Their participation in APA does not replace their proprietary products; rather, it puts major payment-rail builders into a forum intended to align the cross-industry rules and interoperability those products will need.

Startup-program access: Founding members receive early visibility into Rain’s Agentic Startup Program, whose first cohort has five startups and a member-accessible demo day. Program participants receive access to Rain’s card-issuing and money-movement infrastructure, $5,000 of testing credit for card issuance or virtual-account fees, and biweekly expert sessions and office hours. The tooling includes task-limited virtual cards and payment guardrails through Rain’s Agent Control Layer.

What could impede it:

• Regulatory and liability uncertainty: Existing consumer-protection, authorization, AML/KYC, and liability regimes do not map cleanly onto a transaction initiated by an agent.
• Digital-asset risk: Where crypto rather than regulated fiat or stablecoins is used, price volatility can make budgets and settlement values unpredictable; blockchain and smart-contract transfers may also be difficult to reverse after an agent—or attacker—acts.
• Security and privacy: Prompt injection, stolen credentials or wallet keys, malicious merchants, data leakage, opaque model decisions, and weak audit trails could turn delegated authority into unauthorized spending.
• Autonomy versus control: Giving software access to real funds requires explicit mandates, spend limits, merchant/category restrictions, revocation, human escalation, and accountable records—not merely an agent’s assertion that it was authorized. The IMF flags authorization traceability, opacity, cybersecurity, correlated behavior, and unresolved legal and liability questions as central risks.
