YZi Labs, the former venture arm of Binance, led a $25.5 million strategic investment round for Sign, Blockworks has exclusively learned. IDG Capital also participated in the round. 

In January, Sign raised $16 million from YZi Labs, which was also YZi’s first investment after being spun out from Binance after former Binance CEO Changpeng Zhao turned it into a family office. Sign has, in total, raised over $55 million in all three — seed, Series A and strategy — rounds. 

Sign builds digital infrastructure and plans to use the capital to expand its tech team, CEO Xin Yan told Blockworks.
