Verifiable Intent and the Race for a Universal Protocol in Commerce

Agent transactions: With models like the Universal Commerce Protocol, Google aims to control global agent transactions, relying on Mastercard’s verifiable financial infrastructure to make it viable.

Filling voids: Similar to how MCP secures agent access to internal systems, verifiable intent enables agents to securely transact on behalf of humans by closing three gaps in the purchase flow; it secures transactions by validating agent identity, ensures strict adherence to user instructions, and confirms the transaction occurred.

Big picture: Google and Mastercard are racing to lay the foundation for agentic commerce, but if no single standard wins, fragmented protocols could recreate the same consumer confusion seen in past payment wars—all hinging on the assumption that agents will define the future of commerce.
