Coinbase has updated its stablecoin-based payments protocol for AI agents, now called x402 V2. This version introduces features like wallet-based identity and dynamic payment recipients, making it easier for developers to integrate the system into existing services.

Coinbase has introduced Payments MCP, a tool that allows AI agents like Claude and Gemini to access blockchain wallets and perform transactions using cryptocurrency. This initiative follows the launch of the x402 Foundation, aimed at standardizing AI payments and enhancing the integration of AI with decentralized finance.

Google has partnered with Coinbase and the Ethereum Foundation to enhance its open-source AI protocol, allowing AI applications to process payments using stablecoins. This initiative aims to merge AI with digital finance, responding to the rising adoption of stablecoins, which have seen significant growth in circulation this year.

Coinbase has introduced the x402 protocol, transforming the long-unused HTTP 402 status code into a payment layer that enables AI agents to autonomously process payments without human intervention. This innovation facilitates a more efficient system for digital transactions, allowing servers to request payments and clients, including AI agents, to respond using stablecoins like USDC. Other major companies like Visa and PayPal are also exploring similar autonomous payment solutions for AI-driven commerce.
