MultiversX Integrates Google UCP and x402 to Power Agentic Commerce

MultiversX has become the first blockchain to officially integrate Google’s Universal Commerce Protocol (UCP), alongside adding native support for x402, a payment protocol incubated by Coinbase. The dual integration positions MultiversX as a settlement and payment layer for AI-driven, agentic commerce.

The announcement follows Google’s introduction of UCP at the National Retail Federation conference in January 2026, marking a significant step toward automated retail workflows powered by artificial intelligence.

Google Universal Commerce Protocol Comes On-Chain

Google’s Universal Commerce Protocol (UCP) is an open-source framework co-developed with major retailers including Walmart, Target, and Shopify. The protocol is designed to support agentic commerce, allowing AI agents to discover products, check inventory, and complete purchases across platforms without relying on traditional storefronts.

By integrating UCP, MultiversX enables these AI agents to use its sharded blockchain architecture, which is capable of processing over 100,000 transactions per second, as a secure settlement layer for high-volume commercial activity.

The protocol also introduces a unified checkout flow, which can link with digital wallets to remove repetitive form-filling and streamline AI-driven purchasing processes.

Native Support for Coinbase-Incubated x402 Payments

Alongside UCP, MultiversX added native support for x402, a decentralized payment protocol developed by the Coinbase Developer Platform (CDP). The protocol revives the HTTP 402 “Payment Required” status code, enabling web services and APIs to request payment before delivering content.

x402 supports pay-per-use transactions without accounts or subscriptions, allowing both humans and AI agents to make autonomous payments. The system is optimized for machine-driven activity, enabling AI agents to pay for data, compute resources, or digital goods using USDC and other stablecoins.

MultiversX is integrating x402 V2, which is described as multi-chain by default and includes standardized network identification to ensure interoperability across different blockchain networks.

Infrastructure for the Agentic Economy

The combined integration of UCP and x402 positions MultiversX as a core infrastructure provider for the emerging agentic economy, where AI systems transact directly with one another.

MultiversX’s high-throughput design addresses the latency and scale requirements of machine-to-machine payments, which are projected to support trillions of autonomous transactions by 2030. Both integrations emphasize near-zero protocol fees, ensuring that micropayments, often fractions of a cent, remain economically viable.

From a developer perspective, adoption has accelerated rapidly. The protocol has recorded a 10,000% increase in transaction activity since late 2025, with hundreds of thousands of payments processed weekly across AI-integrated APIs.

Strategic Takeaway

By combining Google’s agentic commerce standard with Coinbase’s autonomous payment rail, MultiversX is positioning itself at the intersection of AI, retail, and blockchain infrastructure. The integrations signal a shift toward fully automated, internet-native commerce, where AI agents can discover, transact, and settle value without human intervention or traditional financial intermediaries.
