Google has unveiled an open-source payment protocol designed to give AI applications a single, universal standard for exchanging value. For the first time, the tech giant has embedded stablecoins at the heart of the stack, alongside legacy rails such as credit cards. The move is intended to solve the cross-border settlement, speed and value-transfer headaches that arise when autonomous AI agents start paying one another.

**More Than 60 Partners, from Coinbase to the Ethereum Foundation**

More than 60 organizations—ranging from Coinbase and the Ethereum Foundation to Salesforce and American Express—co-drafted the spec. Google argues that stablecoins bring automation-ready stability and near-zero fees, but admits that fragmented global regulation, stringent security demands and user-education gaps remain high hurdles.

**From Information to Value: AI Agents Get Wallets**

The protocol extends Google’s April launch of a universal messaging layer that lets AI agents “talk.” Adding payments turns those conversations into transactions, shifting AI interaction from information exchange to value exchange. Sub-second programmable networks such as Mysten Labs’ Sui and EigenCloud’s verifiable-compute layer are already integrated, promising both speed and auditability.

**Stablecoins as the Native Cash of the Machine Economy**

Stablecoins, not volatile crypto assets, are cast as the machine-to-machine medium of exchange: dollar-pegged, programmable and borderless. In use-cases ranging from micro-service fees to autonomous shopping carts, they can settle faster and cheaper than card networks or correspondent banking. If adoption accelerates, the project could re-wire how trillions in AI-driven commerce are cleared and settled.

**A Prelude, Not a Product**

Google insists the protocol is additive, not substitutive: legacy rails stay, while new ones plug in. Still, the signal is unmistakable—Big Tech is no longer flirting with crypto from the sidelines. By writing stablecoins into the very blueprint of its AI cloud, Google is betting that the future of payments will be minted in code, not just in fiat.
