Google has launched an open-source protocol enabling AI applications to conduct transactions, including stablecoin payments, in collaboration with Coinbase, Salesforce, American Express, and other major partners.
Google announced an official initiative to release an open-source protocol supporting payments between AI applications, including transactions using stablecoins. The rollout involves partnerships with Salesforce, American Express, and over 60 other firms. Coinbase contributed to developing stablecoin functionality and interoperable payment systems, while the Ethereum Foundation was consulted. The protocol extends Google’s Agent2Agent framework, introduced earlier in April, which already connected AI agents for information exchange. The move highlights growing efforts to link AI systems with decentralized finance protocols and real-world payment use cases.
