The Future of E commerce with Primer I Cynthia Wang

Sun, Nov 2, 2025, 12:00 AM

Cynthia Wang, co-founder of Primer Pay and Stanford student, discusses the future of e-commerce and payments, focusing on bridging Web2 and Web3 through seamless stablecoin transactions. Primer, developed by a team from three universities, enables users to pay with stablecoins on platforms like Amazon via a Chrome extension. The solution abstracts away complex crypto details, targeting mainstream adoption, especially in emerging markets where stablecoin demand is high. Primer converts stablecoins to gift cards for merchant compatibility, emphasizing user experience and integration with existing consumer habits. The team is exploring AI-driven product discovery and checkout, aiming to create a universal aggregation layer for receipts and payments across credit cards, stablecoins, and tokens. Cynthia highlights industry trends like AI agents, Google’s agent payment protocol, and institutional crypto adoption, positioning Primer at the intersection of e-commerce, crypto payments, and AI. The project continues to iterate, with plans for broader platform integration and a focus on user-centric design. 00:00 Introduction 00:38 Team Background & Motivation 01:02 Crypto UX & Decentralization Debate 01:44 Crypto Payments: US vs Emerging Markets 02:03 Bridging Web2 and Web3 02:33 E-commerce Challenges & Opportunities 03:23 Merchant Infrastructure & Trust Issues 03:50 Vision: Universal Aggregation Layer 04:08 Industry Trends & Inspiration 04:37 Building Primer: ETH Global New York 04:56 Demo: Stablecoin Payments on Amazon 05:36 Improving Gift Card Conversion & Expansion 06:15 Target Markets & Use Cases 06:36 User Flow & AI Integration Plans 07:15 Payments Focus & Institutional Adoption 07:33 AI Agents & Microtransactions 07:53 Future of E-commerce & UX 08:26 Community Engagement & Next Steps 08:46 Iteration, Waitlist, and Future Vision 09:04 Conclusion _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *Pragma New Delhi* Pragma New Delhi 2025 was held on September 25th at the JW Marriott Hotel in Aerocity New Delhi and was an in-person summit for builders and leaders in the web3 ecosystem.
