Recently, there has been a clear shift in the narrative of AI Agents: from initially "helping to write code" to now "autonomously spending money."

What does this change signify? I have always used it as an observation indicator—the core signal to determine whether the AI economy can establish a genuine transaction closed-loop. In simple terms, this is not just a marketing story for a certain exchange or project; fundamentally, it is a true return of native micro-payments on the internet.

From the progress in December, the pace of advancement in this direction is accelerating. On December 11, the relevant infrastructure received an important version upgrade—from the "usable" stage gradually evolving to the level of "industry standard candidate." Although this iteration appears to be a technical detail update, it actually reflects a significant increase in the maturity of the entire AI economy payment layer.
