Top SchoolChongyu Yuan is a seasoned technology leader and co-founder/CTO with over a decade of experience building large-scale internet systems, microservices, and secure production platforms across e-commerce and blockchain domains. He has led platform architecture and infrastructure teams at companies like Yihaodian, Baozun, and Omni Prime, and translated that expertise into rapid crypto product launches—most notably designing and shipping an offshore RMB stablecoin and a cross-border OnPay platform that processed $100M monthly.

An active contributor to tooling projects, he has added practical plugins (e.g., an AQI plugin) to popular open-source repos, reflecting a pragmatic full-stack mindset. Based in Shanghai, he blends entrepreneurial drive with deep protocol-level knowledge of Ethereum and web3 innovation.
