YZi Labs (formerly Binance Labs) has led a $25.5 million strategic investment round for digital infrastructure company Sign. Sign secured a $16 million investment from YZi Labs in January, marking the company's first investment since its rebranding. To date, Sign has raised over $55 million in total funding, including seed, Series A, and strategic rounds. The company's CEO, Xin Yan, stated that the new capital will be used to grow its technology team and expand its global operations. Yan said, “We are looking to add top talent to our team with expertise in Hyperledger Fabric, zero-knowledge proofs, and interoperability. We are also establishing local teams in each country.” Chart showing the rise in SIGN price following the development. The new investment will also be used to expand several partnerships aimed at developing sovereign blockchain infrastructure. “The cryptocurrency sector is currently rich in technology but poor in adoption. Both our investors and our team believe it is time to overcome this biggest hurdle by collaborating with countries,” Yan said. “Our goal is to develop innovative solutions that will benefit nations while respecting existing regulations.” The Sign team is currently collaborating with Thailand and South Korea, as well as leading technology countries in Central Asia and the Middle East. “While the concept of blockchain for nations is new, we believe the technology needs to be adopted progressively. Projects like Tempo share this vision. However, we aim to implement a national-level digital currency system before competitors like Ripple or Solana,” Yan added. *This is not investment advice.
