Arc, a company working on financial infrastructure, is developing programmable real-time rails designed to support the agentic economy. The system targets AI-driven microtransactions, aiming to handle small, frequent payments that machines and software agents could make autonomously. If successful, it could reshape how value moves between digital entities.
The Agentic Economy Takes Shape
AI agents are already booking travel, managing inventory, and trading assets. As these agents become more independent, they need to pay for services and data in real time. Traditional payment rails—built for person-to-person or person-to-business transactions—struggle with the speed and volume of machine-to-machine payments. Arc's project directly addresses that gap.
The company is building infrastructure that allows agents to execute payments programmatically. Instead of a human authorizing each transaction, the agent itself can trigger payments based on pre-set rules or AI decisions. That opens the door for new business models where AI agents pay each other for compute time, data access, or completed tasks.
Programmable Rails for Machine-to-Machine Payments
Arc's approach focuses on making the rails programmable. That means developers can embed payment logic directly into the code that runs the agents. Payments can be conditional—only executed when a certain outcome is reached—and can settle in real time rather than in batches. For microtransactions, where amounts may be fractions of a cent, speed and low cost are critical.
The company has not disclosed technical details or a timeline for launch. But the concept aligns with broader trends in the financial industry, where real-time payment systems are becoming more common. What sets Arc apart is the explicit focus on agentic use cases, rather than adapting existing systems.
What Comes Next
Arc's work raises a question the industry has only begun to confront: who builds the financial plumbing for a world where machines are the customers? Traditional banks and payment processors are not designed for millions of microtransactions initiated by AI. Arc is betting that a new layer is needed.
No launch date has been announced. The company is still in development, and the success of the platform will depend on adoption by AI developers and the willingness of regulators to allow autonomous financial transactions. For now, Arc is one of the few companies openly building for this future.
