Google has released a new open protocol that lets artificial intelligence (AI) systems handle payments, including those made with stablecoins.

According to a report by Fortune on September 16, the project is being developed with the support of over 60 companies. Key partners include Salesforce and American Express.

The payment system’s stablecoin features were created with help from Coinbase $2.21B , while the Ethereum ETH $4,511.71 Foundation also gave input during the design phase.

James Tromans, who leads the Web3 team at Google Cloud, confirmed the launch and explained that the protocol works with current payment systems while also being ready to support digital assets like stablecoins in the future.

Coinbase engineer Erik Reppel said their goal was to make it easier for AI tools from different platforms to exchange value between each other.

This new system builds on Google’s earlier Agent2Agent Protocol, which was introduced in April. It was developed with input from more than 50 companies and consultancies, including PayPal, SAP, Deloitte, and PwC.

The latest update adds payment features to that existing foundation. With it, AI agents can share data and manage transactions independently, without human involvement.

This development comes as more companies explore ways to integrate AI agents with decentralized finance (DeFi) systems.
