Building the Future of “Agentic Commerce”: Google’s Web 3 Solutions for Software Developers in South Korea

written by 오지현 (이화체인 15기), 안소은 (MOLOCO, 이화체인 어드바이저)

South Korea has long been recognized as a “Crypto Capital,” but the narrative is shifting from speculative trading to a new frontier: the intersection of AI and Web 3. In Seoul’s tech hubs like Pangyo, the conversation is no longer just about blockchain infrastructure; today, it’s about Crypto Agents.

2026 The Core Trend: From Humans to Agents

Google’s Agentic commerce

Google’s vision for Web 3 centers on Agentic Commerce. While traditional payment rails are too slow for the digital age, stablecoins provide the perfect “economic rails” for AI agents. These agents can operate 24/7, executing swaps, buying NFTs, and managing yields at speeds humans cannot match.

The Google Web 3 Stack: Three Pillars of Growth

To support this evolution, Google Cloud provides a three-pillared offering.

1. Global Infrastructure: Google provides the same GPU and TPU power that runs YouTube and Gmail, ensuring your dApp or AI model can scale globally with Mandiant-grade security.
2. Web 3 Integrations:

• Blockchain Data: BigQuery allows SQL queries across more than 39 chains (including Ethereum, Solana, and Sui).
• Managed Services: 1P RPC endpoints and testnet faucets for chains like Base, Solana, and LayerZero.

3. Strategic GTM: Google doesn’t stop at hosting your code but also helps you sell it through co-sell programs and strategic investments from CapitalG and GV.

Deep Dive: AP2 and UCP in the Korean Ecosystem Context

For software developers in South Korea’s massive gaming and K-culture sectors, two open frameworks are game-changers.

1. **AP2 (Agent Payment Protocol):** An open protocol (linked with partners like Coinbase) that allows AI agents to authorize and execute payments instantly.

• Use Case: Autonomous Gaming Guilds. Imagine an AI agent for a Korean MMORPG guild that monitors the market 24/7 and automatically buys a “Level 50 Shield” for the guild bank the moment it hits a target price.

2. **UCP (Universal Commerce Protocol):** A unified interface that connects agents to thousands of merchants without needing to learn individual APIs.

• Use Case: Frictionless K-Pop Merch. An AI fan-agent performs search across multiple global marketplaces to find the rarest photo card, manage the bridge/swap of assets, and complete the checkout via UCP, all through a single natural language command from the fan.
