Sign Protocol (SIGN) is a Web3 infrastructure project rooted in the Ethereum ecosystem, focusing on two main tracks: credential verification and token distribution. Its predecessor was the well-known on-chain signing platform EthSign. After completing a brand upgrade in 2025, it operates under the core brand Sign, with the native token SIGN becoming the ecological token.
From the price performance perspective, the current exchange rate of SIGN to USDT is $0.03207, with a slight decline of 0.87% in the last 24 hours. The on-chain position concentration is 12.41, and the chip distribution is relatively dispersed. Looking back at its price trend, this token reached an all-time high of $0.1325 on September 24, 2025, and fell to an all-time low of $0.0122 on October 11 of the same year, with a price fluctuation of over 90% in just half a month, reflecting the high volatility characteristics of small and medium-cap cryptocurrencies. On the technical side, the Sign Protocol is developed based on the Ethereum network, and the block data can be queried through Etherscan. The team has also launched a deployment toolkit based on Foundry, supporting CREATE3 deterministic deployment and version management, enabling automation and traceability of token distribution and contract deployment. This technical optimization addresses the problems of low efficiency and difficult traceability in traditional on-chain deployment, laying a foundation for the technical implementation of the project.
