Google has made another big move. Today, Google CEO Pichia announced the official launch of Universal Commerce Protocol (UCP), aiming to lay the foundation for the future era of "agentic commerce". Simply put, it means enabling AI agents to help us complete the entire shopping process like human assistants - from discovering products, recommending, comparing prices, placing orders and payments, to after-sales service, fully automated and seamlessly connected. How to understand UCP? UCP is an open standard protocol that provides a "universal language" for AI and e-commerce systems. Previously, each AI assistant (such as Gemini, ChatGPT, or other agents) and each merchant needed to separately interface and develop interfaces, which was very cumbersome. Now with UCP, all AI agents, shopping platforms, retailers, and payment providers can use the same standard "chat" to achieve smooth cooperation across platforms and systems. UCP is also jointly developed by Google and e-commerce companies such as Shopify, Etsy, Wayfair, Target, Walmart, etc. Many payment giants also support UCP, such as American Express、Best Buy、Flipkart、Macy’s、Mastercard、Stripe、The Home Depot、Visa、Zalando Wait. In the future, we can directly buy things in the AI Mode of Google search or Gemini application. for example Can you help me find a warm down jacket suitable for winter wear with a budget of less than 2000 yuan AI directly recommends, compares, and applies coupons to you You said 'buy this' → Directly pop up the checkout page and use Google Pay or saved information for one click payment, without having to jump to other websites throughout the process. This means that future shopping will become increasingly conversational and automated, with AI agents becoming your primary assistants for shopping. This UCP is also compatible with other existing protocols, such as: Agent2Agent (A2A): Communication between agents Agent Payments Protocol (AP2): Secure payments (supports Google Pay, PayPal, etc.) Model Context Protocol (MCP): AI context sharing UCP can also add x402 protocol to achieve instant settlement of stablecoins. The official EVM x402 and UCP reference examples are also provided. This commercial technology stack includes: 1) UCP processing product discovery; 2) X402 handles instant payments; 3) Blockchain verification settlement. The entire process is 100% autonomous and 100% open-source. After Coinbase's x402, Stripe's ACP, and now Google UCP, the era of proxy commerce has arrived
