Google Brings Crypto to AI Payments
Google has launched an open-source protocol that lets AI systems send and receive payments. The system includes support for stablecoins, highlighting the growing role of crypto in powering the digital economy.
The initiative was rolled out with Salesforce, American Express, and over 60 other companies. Crypto exchange Coinbase worked with Google to build stablecoin functionality. The Ethereum Foundation also provided input.
James Tromans, Google Cloud’s head of Web3, said the protocol supports traditional payments and new forms like stablecoins. Coinbase engineer Erik Reppel added that the goal is making AI agents capable of moving value between each other.
From Agent2Agent to Stablecoin-Powered AI
The protocol expands on Google’s Agent2Agent framework, introduced in April. That framework allows AI agents — software that can act without human help — to exchange data and interact efficiently. Partners included PayPal, Salesforce, SAP, Deloitte, McKinsey, and PwC.
This move reflects a bigger push to connect AI systems with decentralized finance (DeFi). Combining the two could simplify trading, improve user experience, and unlock real-world payment cases.
Stablecoins at the Center of AI
Stablecoins are dollar-linked tokens designed to reduce crypto’s price swings. They may become AI’s favorite tool. In fact, Galaxy Digital CEO Mike Novogratz predicted AI agents will one day be the biggest stablecoin users.
The Ethereum Foundation has echoed that view. It highlighted a dormant HTTP code (402, “payment required”) paired with Ethereum’s EIP-3009 standard. Together, they could allow AI agents to trigger stablecoin payments automatically.
As Tromans put it, Google’s latest project isn’t just about payments today. It’s about building the rails for how AI and crypto will power tomorrow’s economy.
