On October 21, 2025, digital infrastructure company Sign (SIGN) announced the completion of a strategic financing round of $25.5 million, led by renowned investment firm YZi Labs and with participation from IDG Capital.
This is already the second time YZi Labs has led the financing of Sign in a short period. Previously, in January 2025, Sign received an investment of $16 million from YZi Labs.
As of now, Sign has raised a total of over 55 million dollars through seed round, Series A, and this strategic round of financing.
01 Financing Details: YZi Labs doubles down, accumulating over 55 million in financing.
YZi Labs’ continuous investment highlights its strong confidence in the Sign project. As a reputable successful fund known for selecting projects at various stages, its endorsement brings significant credibility to Sign.
This strategic financing of 25.5 million USD will mainly be used to expand the technical team, focusing on recruiting experts in the fields of Hyperledger Fabric, zero-knowledge proofs, and cross-chain interoperability technologies.
Sign also plans to establish local teams in multiple countries to promote the construction of sovereign blockchain infrastructure.
02 Market Reaction: The price of SIGN token instantly rose, revealing liquidity concerns.
After the financing news was announced, the SIGN token market reacted very quickly. The token price soared from $0.028 to a high of $0.059, with an astonishing rise.
However, what follows is the issue of insufficient liquidity. After the price rose, it was unable to be maintained and quickly fell back to around 0.042 dollars.
According to MITrade data, SIGN reached a maximum of 0.055 USD on October 21, then fell back to 0.047 USD, with a maximum intraday rise of 25%.
The trading volume also surged, with a transaction amount exceeding 75 million dollars in the past 24 hours, setting a new weekly high.
The derivatives market also reacted strongly, with the open interest in SIGN soaring to a new high of over $12 million.
03 Project Positioning: Ambition to Build Digital Identity Infrastructure
Sign is not an ordinary blockchain project; it carries the grand goal of building a decentralized digital identity authentication infrastructure.
The project aims to enable users to connect existing credentials with a blockchain-based identity system, thereby bringing traditional internet users into a decentralized network.
This vision has broad prospects in today’s digital age, with urgent demands for secure and controllable digital identities from individual users to enterprises and even government levels.
Sign CEO Xin Yan clearly stated that the company is committed to building digital infrastructure and plans to use the funds from this round of financing to expand its technical team and develop partnerships aimed at promoting sovereign blockchain infrastructure.
04 Token Economy: Low Circulation and Future Dilution Risks
Understanding the SIGN token economic model is crucial for assessing its long-term value. As of now, the total supply of SIGN is 10 billion tokens, but only 14.9% of the tokens are in circulation.
This low liquidity situation makes SIGN regarded as a low liquidity token, with a current market value of approximately 64 million USD.
If all tokens are fully unlocked, the fully diluted market capitalization based on the current price will reach up to 483 million dollars.
The token unlock plan will continue until 2030, including linear unlocks and occasional phased unlocks.
This continuous unlocking may bring future selling pressure risks and dilution effects, which are important factors that investors need to be vigilant about.
05 Development Prospects: Future Layout of Sovereign Digital Identity Systems
Sign’s ambition goes beyond the personal user domain. After completing the token distribution and building the main product for on-chain credentials in the early stages, the project is now turning its attention to a broader market - building sovereign digital infrastructure for governments.
The project plans to develop an integrated system that includes digital identity, currency, and verifiable credentials.
BNB Chain will become the foundational layer for all Sign applications, including those aimed at sovereign identity, designed to provide a scalable national-level blockchain system.
This strategic positioning allows Sign to participate in the construction of a national-level digital identity system, with immense potential for imagination.
06 Investment Considerations: Opportunities and Risks Coexist
For investors interested in SIGN, it is crucial to recognize the opportunities and risks.
On the positive side, Sign has received ongoing support from top investment institutions, the project positioning has strategic significance, the team is actively recruiting top talent, and the project is committed to addressing the real pain point of digital identity.
The risks cannot be ignored: the tokens are highly concentrated, with the top five addresses holding a total of 88.75% of the total supply, liquidity is relatively insufficient, and prices are easily affected by large transactions. The token unlocks that will continue until 2030 may bring long-term selling pressure, and the fully diluted market cap is already quite high, which may limit the short-term rise.
The risk of technical execution also exists, and the cross-chain identity system planned by Sign is highly complex and faces intense competition.
Future Outlook
The significant price volatility highlights the market’s positive reaction to the Sign financing news, but also exposes its shortcomings in liquidity.
In the long run, Sign’s vision of building a digital identity infrastructure is quite attractive, with a total funding of $55 million and endorsements from well-known investment institutions providing a solid foundation for the project’s development.
However, investors need to be clearly aware of the high concentration of tokens and the dilution risks brought by future unlocks, and make investment decisions cautiously.
