YZi Labs has made a strategic investment into blockchain infrastructure company Sign, leading a follow-on funding round alongside IDG Capital. This is an expansion on the initial investment YZi Labs made in Sign back in December 2024. To date, Sign has secured over $55 million in total funding through seed, Series A, and strategic rounds. Sign’s mission evolved beyond token distribution and on-chain credentials to a broader focus on sovereign blockchain infrastructure for governments. The company aims to build national blockchain systems that encompass digital identity, currency, and verifiable credentials using BNB Chain as the base layer for its applications.
