x402, this payment protocol, is making new moves again—expanding from AI payments to transfers and settlements between robots.

Stablecoin giant Circle recently partnered with the robot network OpenMind, preparing to jointly develop payment rules for the robot economy. It sounds pretty sci-fi, but if you think about it, it makes sense: if robots really become the main productive force in the future, they'll definitely need a reliable settlement system for transactions between them.

When x402 first emerged, people were already discussing the possibility of autonomous AI trading. Now it looks like this path is truly moving forward—starting with micro-payments between AI agents, and now directly targeting the financial infrastructure of entire robot networks.

Whether or not you believe AI will rule the world, at the very least, the application scenarios for crypto payments in non-human economies are becoming much more concrete. This move is, to some extent, laying the foundation for the "financial pipelines of the future world."
