AI Agents Drive Millions of On-Chain Transactions via Base Blockchain
Autonomous artificial intelligence systems are rapidly evolving from conversational interfaces into economic actors capable of executing their own financial settlements. According to blockchain analytics firm Chainalysis in its Inside North America’s $3 trillion crypto economy: Agentic commerce accelerates report released Wednesday, AI agents are actively purchasing services, acquiring data, and paying for access to AI model tokens. The research reveals that more than 138 million transactions have already been recorded through the x402 protocol deployed on Coinbase’s Layer-2 Base blockchain.
This surge in autonomous machine-to-machine activity highlights the emergence of “agentic commerce,” a paradigm where software programs independently manage digital wallets to complete microtransactions and access computational resources on demand. The findings underscore the speed at which autonomous software is moving beyond centralized payment rails and adopting decentralized infrastructure to settle balances in real time.
United States Dominates Global AI Model Inference Payments
Geographic analysis from Chainalysis shows an overwhelming concentration of agentic activity originating from North America. Wallets linked to the United States accounted for 88.1% of all geographically identified payments designated for AI model inference. In stark contrast, wallets tied to China represented only 0.1% of these transactions, revealing a massive divergence in how the two artificial intelligence superpowers consume computing power.
Researchers attribute this disparity to structural differences in the technical ecosystems and model architectures preferred in each region. “One possible explanation is that Chinese developers are more inclined to use open-weight models such as DeepSeek and Qwen, reducing their need to purchase metered inference services,”
Eric Jardine, Chainalysis’ head of research, told CoinDesk.
Payment Giants and Crypto Infrastructure Back Machine Commerce
The institutional foundation supporting agent-driven transactions is expanding rapidly across traditional finance and decentralized platforms. Major payment networks, including Visa, Mastercard, and Stripe, have moved to support the x402 protocol, signaling strong corporate interest in establishing standards for autonomous payments. Concurrently, Coinbase has expanded its infrastructure by allowing commercial clients to directly accept digital payments sent by AI agents.
Why This Matters
The transition toward agentic commerce represents a fundamental shift in how digital services are consumed and monetized. Historically, software access relied on recurring human subscriptions or manual credit card billing. By utilizing blockchain rails such as Base and protocols like x402, AI agents can execute frictionless, programmatically triggered micropayments for precise computing resources. As heavyweights like Stripe, Visa, and Mastercard integrate with these ecosystems, the boundary between automated machine intelligence and commercial financial infrastructure is rapidly dissolving.
Frequently Asked Questions
What is the x402 protocol?
The x402 protocol is a payment standard operating on Coinbase’s Base blockchain that enables autonomous artificial intelligence agents to conduct commercial transactions, such as buying data, paying for metered inference, and accessing specialized AI models.
Why do U.S. wallets represent the vast majority of inference payments?
U.S.-linked wallets represent 88.1% of identified inference payments, largely due to high domestic adoption of proprietary, metered cloud-hosted models. In contrast, Chinese developers often leverage open-weight alternatives such as DeepSeek and Qwen, which can be run locally or independently, significantly reducing the demand for paid, metered inference calls.
Which major financial firms are supporting AI agent transactions?
Traditional payment giants including Visa, Mastercard, and Stripe have backed the x402 protocol, while crypto exchange Coinbase has enabled its business customers to receive payments directly from AI agents.
