Google introduces the Agent Payments Protocol (AP2) to enable autonomous AI financial transactions.
The initiative bridges blockchain technology with conventional financial systems.

On September 16, 2025, Google announced the launch of its open-source Agent Payments Protocol (AP2), a system that allows artificial intelligence (AI) agents to autonomously send and receive money. The protocol includes support for stablecoins and was developed in collaboration with Coinbase, alongside input from over 60 companies such as Salesforce, American Express, and Etsy.

The AP2 protocol connects traditional financial systems with blockchain technology, enabling AI agents to process transactions through both conventional methods like credit and debit cards and blockchain-based digital currencies. This financial layer builds upon Google’s earlier Agent-to-Agent (A2A) specification, which standardizes AI communication, by adding automated settlement capabilities.

James Tromans, Web3 lead at Google Cloud, explained that AP2 was designed to integrate with existing financial infrastructures while introducing advanced features like stablecoin transactions. The system emphasizes automation, auditability, and user-consent mechanisms to ensure secure and reliable operations.

This initiative aligns with Google's broader strategy of building blockchain infrastructure for financial-grade applications. Another significant project under this strategy is the Google Cloud Universal Ledger (GCUL), which aims to support programmable transactions and institutional settlements.

Meanwhile, the Ethereum Foundation has announced a "decentralized AI" (dAI) team, which intends to position the Ethereum blockchain as a foundational platform for AI-driven commerce. This reflects a larger industry movement toward integrating AI and blockchain technologies.

As of September 16, 2025, Ethereum (ETH) is valued at $4,439.74, experiencing a 1.53% drop in 24-hour trading volume, while USDC remains stable at $1, with a 0.003% decrease in 24-hour volume, according to CoinMarketCap.
