After in-depth research on the Sign project, I have gained a clearer understanding of its potential in the global digital infrastructure field. The Sign Protocol, as a full-chain certification protocol, has become the underlying layer of government-level public digital infrastructure, capable of supporting identity verification, proof of ownership, and execution of smart contracts; while TokenTable provides smart contract-driven token distribution capabilities, covering airdrops, vesting management, and unlocking mechanisms, truly achieving integration from the application layer to the distribution layer.
In terms of financing, Sign has raised a total of $32 million: $14 million support from Sequoia Capital in the seed round in 2022, and $16 million in Series A funding led by YZi Labs in 2025. In terms of real-world implementation, Sign has already provided national-level digital infrastructure for the UAE, Thailand, and Sierra Leone, and plans to expand to over twenty countries including Singapore and Barbados, demonstrating strong international layout capabilities.
What is even more noteworthy is that Sign achieved $15 million in revenue in 2024 and maintained profitability, while completing a $12 million SIGN buyback, releasing positive signals for investors. Combined with its launch on Binance Alpha and the continuous expansion of real application scenarios, $SIGN possesses great imagination in terms of long-term investment value and valuation space.
