Agentic commerce — where autonomous software agents buy and sell on behalf of humans — will require crypto payment rails, senior representatives from PayPal and Google Cloud said this week at Consensus Miami. The two companies argued that existing financial infrastructure isn't built for machines that negotiate and transact without direct human oversight. They called for open payment protocols, machine-readable merchant catalogs, and multi-party crypto custody as the foundational pieces.
Open protocols and machine-readable catalogs
According to the executives, traditional payment networks work fine when a person clicks a button. But software agents need standardized, machine-readable data to discover pricing, availability, and terms across thousands of merchants. The reps said that open protocols — not walled-garden APIs — are the only way to let agents shop around and execute trades programmatically. Machine-readable catalogs would let an agent compare offers in real time, much like a human might browse a comparison site, but at machine speed.
Multi-party custody requirement
Another key requirement the speakers laid out is multi-party crypto custody. If an agent holds funds to spend on behalf of a user, the risk of theft or misdirection is high. Multi-party custody — where multiple independent parties must authorize a transaction — could act as a safety net. The Google Cloud representative specifically noted that this kind of setup would let different entities verify agent actions before funds move, reducing the chance of exploits or rogue behavior.
Consensus Miami panel
The comments came during a panel focused on the intersection of AI agents and blockchain payments. Both PayPal and Google Cloud have been pushing deeper into crypto services — PayPal with its stablecoin and checkout features, Google Cloud with blockchain node hosting and data services. The timing is notable: agentic commerce is still a niche concept, but the infrastructure talk suggests major payment firms see a real use case coming. Neither company announced any specific product launch. They framed their remarks as a call to action for the broader crypto and developer communities to build the pieces.
No timeline was given, but the panel signaled that both companies are actively exploring how their existing platforms could support agent-driven transactions. The next concrete step, according to the executives, is getting the industry to agree on standard formats for merchant data and custody arrangements. Without those standards, even the best agent software can't actually spend money reliably.
