Sign Secures $25.5M Strategic Funding Led by YZi Labs

Strategic Funding Accelerates

Blockworks reports that Sign has secured $25.5 million in its latest strategic funding round, led by YZi Labs with IDG Capital as a co-investor. CEO Xin Yan noted that the new capital will primarily be used to expand Sign’s technology team and further enhance its technical capabilities in the digital infrastructure space.

Sign is focused on digital asset infrastructure, with core expertise in token distribution and on-chain credential verification. From January’s $16 million round to this October’s strategic funding, YZi Labs’ ongoing support underscores strong confidence in Sign’s technology direction and long-term value proposition.

Strategic Purpose Behind the Investment

This investment is far more than a simple financial transaction—it’s a critical component of YZi Labs’ long-term strategic roadmap. The YZi Labs portfolio reveals a systematic approach to building a complete digital asset ecosystem. From stablecoin issuer Avalon Labs, AI hardware innovator USD.AI, and illiquid asset liquidity provider Aspecta, to Sign and Temple Digital Group, YZi Labs’ strategy spans the full spectrum from foundational technology to institutional-grade financial infrastructure.

Sign plays a pivotal role in this framework: acting as a bridge between the crypto-native sector and sovereign nations, it brings its S.I.G.N. technology stack into regulated environments. This strategy is fully aligned with YZi Labs’ long-term vision for institutional digital asset adoption. The partnership was brokered directly by CZ, amplifying Sign’s market impact.

Sign’s Evolution and Industry Significance

Sign’s growth path reflects the broader trajectory of the industry. Originally known as EthSign and focused on Web3 infrastructure, the company later rebranded to prioritize transparency and security in token distribution. Today, it is extending its reach to deliver comprehensive blockchain technology stacks for sovereign governments. This progression illustrates the blockchain sector’s maturation—from serving crypto-native users (retail/C-side), to developing financial infrastructure (enterprise/B-side), and now collaborating with sovereign entities (government/G-side) to drive large-scale adoption and mainstream legitimacy. Sign’s journey exemplifies how digital infrastructure innovators transition from niche disruption to mainstream application.

Technology and Infrastructure Value

Sign’s projects address the digital era’s demand for secure, verifiable, and user-friendly credentials. By integrating blockchain, smart contracts, and privacy safeguards, Sign delivers a decentralized, multi-chain network solution for verifying identity, ownership, and agreements—positioning itself as both a technology innovator and a trusted infrastructure provider in the digital asset ecosystem. Institutions and developers benefit from scalable, compliant on-chain services tailored for the evolving regulatory landscape.
