Diameter Pay, a stablecoin payment infrastructure startup, has announced a $10 million funding round led by a prominent venture capital firm, with participation from several payment and blockchain-focused institutions. The company specializes in machine-to-machine payment solutions for AI agents and automated systems, with its core product built on the x402 protocol, enabling agents to initiate and settle USDC transactions without human intervention.

According to the announcement, the funds will be used to expand compliance and pre-settlement screening capabilities, including KYC/KYA processes, sanctions list filtering, and on-chain taint detection, to address the growing need for authorization intent and limit management in agent-initiated payments.

Founded in 2025 and headquartered in the United States, Diameter Pay is currently in talks with multiple payment service providers and stablecoin issuers for potential partnerships.

Industry observers note that as AI agents autonomously execute transactions in e-commerce, content distribution, and other scenarios, infrastructure layers like Diameter Pay are becoming critical nodes connecting the agent ecosystem with traditional financial systems.
