Dialogue with Jia Hang | Looking Back at Two Decades of Chinese Payment Going Global

**Summary: A Conversation with Jia Hang on Two Decades of China's Payment Globalization** Jia Hang, a veteran with over twenty years in payments, reflects on China's attempts to build a global payment network through three key phases: UnionPay (card networks), Alipay+ (digital wallets), and now, stablecoins. His journey began at UnionPay International, aiming to establish China's card network abroad. While successful in following Chinese tourists ("where Chinese go, UnionPay goes"), it struggled to achieve true global scale. The core lesson: card networks like Visa/Mastercard's unassailable advantage isn't just technical standards, but their deeply entrenched **governance and profit-sharing models** that create powerful network effects. Competing as the "same species" is nearly impossible. At Ant Group, he led Alipay+, a strategy to bypass card networks by interconnecting local e-wallets worldwide. While innovative, it faced a similar ceiling. Mobile QR payments and card swipes were essentially **the same species competing for the same pie**, lacking a disruptive value proposition for users or a sustainable new incentive model to replace the card networks' established flywheel. Today, at Singapore's DCS, Jia focuses on stablecoin-based payments. He argues stablecoins represent a fundamental shift. They are not competing with Visa for consumer payments but challenging the **traditional banking and account system for value movement**. Products like "U Cards" (stablecoin-linked payment cards) are transitional, leveraging existing card networks for acceptance while building new rails. The real potential lies in stablecoins enabling seamless, low-cost global value transfer, potentially reorganizing the financial infrastructure around **accounts rather than cards**. Jia believes stablecoin adoption for local retail payments, cross-border transactions, and as high-yield savings vehicles is becoming irreversible. This could gradually reduce reliance on traditional fiat channels, especially in regions with weak currencies or capital controls. The quest for the "next global payment network" continues, now centered on whether stablecoins can successfully bridge Web2 and Web3, establish new governance, and create compelling user value beyond mere cost reduction.

Vying for the AI Payment Track: Traditional Card Networks Face Off Against Coinbase

As AI agents increasingly conduct commercial transactions, a battle for control over the underlying payment infrastructure is unfolding. The competition centers on two divergent and incompatible technical approaches for autonomous AI payments. One camp, led by traditional card networks Visa and Mastercard, relies on tokenized card credentials within the established banking rails. Visa's "Intelligent Commerce" and Mastercard's "Agent Pay" services extend their existing tokenization technology to authorized AI agents for consumer retail transactions, leveraging decades of fraud protection and dispute resolution systems. Their partners include major AI firms like Anthropic, OpenAI, and Microsoft. The opposing camp, spearheaded by Coinbase, advocates for an open internet protocol using stablecoins. Coinbase's x402 protocol utilizes the HTTP 402 status code to enable direct, machine-to-machine micropayments with USDC on-chain. This model eliminates card fees and is designed for high-frequency, low-value transactions between AI agents, such as paying for API calls or data streams, where traditional card costs are prohibitive. Currently, application scenarios are clearly divided. Mainstream consumer-facing AI shopping services (e.g., ChatGPT's "one-click checkout," Amazon's AI-assisted shopping) predominantly use card channels due to their mature consumer protections and merchant networks. Conversely, the stablecoin channel dominates machine-to-machine payments, as seen in Amazon Bedrock's core payment service using Base blockchain. Significantly, traditional card networks are not solely defending their turf; they are also investing in the stablecoin arena. Visa has rapidly expanded its stablecoin settlement volume and partnered with Coinbase on interoperability, while Mastercard moved to acquire stablecoin platform BVNK. This dual-strategy indicates their intent to become the fee-collecting gateway for all payment flows, regardless of the underlying rail. The short-term outlook is for coexistence: cards for personal retail, stablecoins for machine transactions. The long-term outcome hinges on whether AI-driven commerce will resemble traditional retail or evolve into a vast network of machine micropayments. Visa and Mastercard's hedging strategy suggests they are prepared for either future, while companies betting on a single channel face greater risk.

a16z: The Real Opportunity for Stablecoins Lies Not in Disruption but in Filling the Gaps

The article argues that the true opportunity for stablecoins lies not in displacing traditional card networks like Visa and Mastercard, but in serving new types of merchants that cannot access conventional payment systems. While some in the crypto community believe AI agents will bypass card networks to avoid fees, the author contends cards will dominate most transactions due to their consumer protections (e.g., chargebacks), fraud detection, rewards, and existing infrastructure. Card networks are already adapting to new use cases like AI-driven commerce. The real stablecoin opportunity exists in the emerging wave of AI-native developers and micro-businesses. These entities—often without legal structure, websites, or traditional banking—are creating tools and generating revenue but are unable to meet the risk and compliance requirements of traditional payment processors. For them, stablecoins are currently the only viable way to receive payments, filling a critical gap until traditional systems adapt. Thus, stablecoins serve not as a replacement for cards, but as essential infrastructure for the next generation of merchants that existing systems cannot yet underwrite.
