The soaring SIGN is the native token of the Sign Protocol. The Sign Protocol is a decentralized full-chain verification protocol aimed at providing on-chain identity verification and token distribution services for the Web3 ecosystem. Specifically as follows:

- Function: SIGN serves as a utility and governance token for paying protocol fees, participating in governance decisions, and ensuring network security. By holding and using SIGN, users can access various services and benefits within the Sign ecosystem, and community members can influence the future development of the protocol through holding and participation.

- Token Distribution: The total supply of SIGN is 10 billion tokens, which will be minted on the Ethereum mainnet and distributed through the BNB Chain and Base. The distribution plan emphasizes community incentives and long-term development, with 40% allocated for community incentives, 20% for supporters, 10% for early team members, 10% for the ecosystem, and 20% for the foundation, among others.

- Project Development: Sign originated from the EthSign on-chain document signing platform in 2021, and in 2024 launched the Sign Protocol, expanding into on-chain identity verification and token distribution infrastructure. The project has served over 200 projects, generating annual revenue of 15 million dollars, and completed a 12 million dollar seed round financing in 2022, followed by 16 million dollars in financing in 2025. The SIGN token went live on Binance on April 28.
