Blockchain infrastructure developer Sign has raised $25.5 million in a strategic investment round led by YZi Labs and IDG Capital, according to a Tuesday announcement. YZi Labs has doubled down on Sign after leading the company’s Series A round.
The fresh capital will be used to support the company’s expansion of strategic partnerships and recruitment of technical experts to bridge traditional financial systems with decentralized technology.
Founded in 2021, Sign focuses on implementing a secure blockchain infrastructure for digital identity, payments, and public service systems. The company previously raised funding from all three branches of Sequoia Capital, Circle, and Amber. Its team includes cryptographic and computer science experts from Harvard, Cornell, Columbia, UC Berkeley, and USC.
Sign’s technology is already integrated with Singapore’s Singpass under the Electronic Transactions Act, with projects spanning across Asia and the Middle East. The company aims to serve 50 million people in its first year of operation.
“While blockchain and sovereign nations may hold different ideological foundations, they can in fact benefit greatly from each other,” said Xin Yan, Co-founder and CEO of Sign. “Our goal is to deliver blockchain-based services to 50 million people in the first year, and to gradually shape a global protocol that connects nations through technology. There are only 192 clients in the world, and we’re moving fast.”
The company is led by CEO Xin Yan, a former hardware engineer turned crypto venture capitalist, and CTO Jack Xu, who previously taught the Blockchain Minor program at the University of Southern California.
Dana H., Investment Partner at YZi Labs, said in a statement that Sign’s development is a natural progression from serving individual users to enterprises and now to sovereign clients, enabled by the BNB Chain ecosystem. The backing reflects a shared vision of blockchain as a critical enabler of digital sovereignty and modern governance.
“We’ve known Xin and the Sign team from their early token days. We’ve seen their evolution: from users to enterprises, now to nations. Supporting Sign, built on BNB Chain, enables digital sovereignty and public infrastructure for future societies,” she stated.
