YZi Labs has announced that it led a $25.5 million strategic funding round in Sign, a blockchain infrastructure company developing sovereign digital identity and payment systems. The round also included participation from IDG Capital and several other institutional investors, underscoring growing confidence in blockchain answers designed for national-scale digital services.
With this latest round, Sign’s total funding has surpassed $55 million, reflecting sustained investor interest in the company’s mission to create decentralized digital identity frameworks and data infrastructure for governments and enterprises. The funds will be used to expand Sign’s technical team, accelerate research and development, and deepen partnerships focused on real-world blockchain adoption.
Driving innovation in sovereign blockchain systems
Sign’s core technology enables secure and verifiable digital identity management, cross-border payment capabilities, and data sovereignty answers tailored for public and private sector applications. The company aims to provide governments with infrastructure that balances innovation with privacy, enabling nations to operate digital ecosystems under their own regulatory and security frameworks.
The investment from YZi Labs marks a continuation of its strategy to back blockchain projects that offer tangible real-world utility. Formerly known as Binance Labs, YZi Labs has shifted its focus toward infrastructure-oriented ventures that can drive mainstream blockchain adoption. Its participation in Sign’s round highlights growing investor emphasis on blockchain applications that bridge Web3 innovation with practical government and enterprise use cases.
Expanding digital identity and national infrastructure
As digital transformation becomes a global priority, sovereign blockchain infrastructure is emerging as a cornerstone for secure, interoperable identity systems and data management. Sign’s approach positions it at the center of this transformation, offering technology that allows nations to build decentralized yet compliant digital ecosystems. The company’s platform supports verifiable credentials, digital payments, and secure data platform, enabling seamless interaction between citizens, enterprises, and governments.
According to the company, the newly raised capital will support the rollout of pilot programs with government partners and major enterprises across emerging markets. Sign also plans to introduce new features aimed at improving scalability, interoperability, and developer accessibility within its blockchain framework.
The investment round comes at a time when global interest in blockchain-based identity and infrastructure is accelerating. Governments in regions such as Asia, Africa, and Latin America are exploring blockchain technology to strengthen digital governance, improve transparency, and modernize public services. Sign’s technology aligns closely with these goals, providing secure, sovereign digital identity systems that integrate with both legacy and decentralized frameworks.
YZi Labs’ involvement also signals broader investor movement toward infrastructure-level blockchain answers rather than speculative applications. As institutional capital continues to flow into projects addressing real-world challenges, companies like Sign are expected to play a defining role in shaping the next generation of digital infrastructure.
The funding underscores how sovereign blockchain answers are transitioning from experimental to essential, offering the foundation for secure digital identity, payments, and data management in an increasingly interconnected global economy.
