In the Web3 world, many projects are still at the 'application layer', but what truly supports global scalable development is the underlying infrastructure. @Sign Official is one of the leaders in this field.
The core of Sign is the Sign Protocol, a full-chain authentication protocol. It is not only the cornerstone of decentralized applications but also a digital public infrastructure provided for governments and institutions. Through this protocol, identity verification, ownership proof, and contract confirmation can be achieved, making on-chain behavior more transparent and trustworthy. Based on this capability, Sign has already taken the lead in real-world scenarios, providing national-level digital identity and credential verification systems for the UAE, Thailand, and Sierra Leone, with plans to expand to more than twenty countries including Singapore and Barbados.
In addition to identity infrastructure, Sign has also created TokenTable—a smart contract-driven token distribution platform. It supports airdrops, unlocks, vesting periods, and other fully transparent management processes, allowing project parties to distribute tokens in the most compliant and intuitive way. For users, this means that every token transfer is clear and traceable, significantly enhancing trust.
On the capital and market front, Sign's growth is equally impressive. Since 2022, the company has raised a total of $32 million: the seed round was led by Sequoia Capital (USA, China, India, Southeast Asia), and the Series A was led by YZi Labs with $16 million. Meanwhile, Sign achieved $15 million in revenue in 2024 and has become one of the few profitable Web3 infrastructure providers.
Whether it is the national-level implementation in the real world or the token economy within Web3, Sign is reshaping trust through infrastructure. As more countries and institutions come on board, it is expected to become the underlying standard for global credential verification and token distribution.
