Google has launched a new open-source AI payment protocol, Agentic Payments Protocol (AP2), allowing AI systems to make secure, compliant transactions using both traditional payment methods and stablecoins. The initiative, developed with Coinbase and over 60 organizations including Salesforce and American Express, reflects Google's growing involvement in decentralized finance. Google Cloud already accepts stablecoin payments via PayPal's PYUSD and views stablecoins as a major upgrade to global payments. Stablecoins now process settlements totaling $1.39 trillion monthly, with market size exceeding $280 billion as of early 2025. U.S. banks have raised concerns over potential deposit outflows, while Coinbase argues stablecoins strengthen the dollar internationally.
