Today, $Alphabet(GOOGL.US) officially announced the launch of the Universal Commerce Protocol, laying the foundation for future Agentic commerce, enabling AI agents to complete the entire shopping process—from product discovery, recommendations, price comparison, order placement and payment, to after-sales service—fully automated and seamlessly connected, just like a human assistant.

How to understand UCP?

UCP is an open-source standard protocol, like creating a "universal language" for AI and e-commerce systems. Previously, each AI assistant and merchant needed separate integration and interface development, which was very cumbersome. With UCP, all AI agents, shopping platforms, retailers, and payment providers can "communicate" using the same standard, enabling smooth cross-platform and cross-system collaboration.

UCP was also co-developed by Google with e-commerce companies like Shopify, Etsy, Wayfair, Target, and Walmart, and many payment giants have already supported UCP.

In the future, we can directly make purchases in Google Search's AI Mode or Gemini. For example:

You ask Gemini: "Help me find a warm down jacket suitable for winter, budget within 2000 yuan."

→ AI directly recommends, compares prices, and applies coupons for you.

→ You say "Buy this."

→ A checkout page pops up directly, allowing one-click payment via Google Pay or saved information, without needing to jump to other websites. This means future shopping will become increasingly "conversational" and "automated," with AI agents becoming your primary shopping assistants.

UCP can also integrate the x402 protocol to enable instant stablecoin settlements. The official also provides reference examples of EVM x402 and UCP.

1) UCP handles product discovery;

2) x402 handles instant payments;

3) Blockchain verifies settlements.
