Blockchain infrastructure developer Sign has raised $25.5 million in a strategic investment round led by YZi Labs and IDG Capital, according to an announcement Tuesday. YZi Labs doubled down on Sign after leading the company’s Series A round.
The new capital will be used to support the expansion of the company’s strategic partnerships and the recruitment of technical experts to bridge traditional financial systems with decentralized technology.
Founded in 2021, Sign focuses on implementing secure blockchain infrastructure for digital identity, payment and public service systems. The company had previously raised funds from the three branches of Sequoia Capital, Circle and Amber. Its team includes cryptography and computer science experts from Harvard, Cornell, Columbia, UC Berkeley and USC.
Sign’s technology is already integrated into 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.
“Even though blockchain and sovereign nations may have different ideological underpinnings, they can actually benefit greatly from each other,” said Xin Yan, co-founder and CEO of Sign. “Our goal is to provide blockchain-based services to 50 million people in the first year and gradually shape a global protocol that connects nations through technology. There are only 192 customers worldwide and we are moving quickly.”
The company is led by CEO Xin Yan, a former hardware engineer turned cryptocurrency 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 the development of Sign is a natural progression from serving individual users to businesses and now sovereign clients, enabled by the BNB chain ecosystem. This support reflects a shared vision of blockchain as a critical enabler of digital sovereignty and modern governance.
“We have known Xin and the Sign team since their beginnings. We have seen their evolution: from users to enterprises, now to nations. Sign’s support, built on the BNB chain, enables digital sovereignty and public infrastructure for future societies,” she said.
