About Sign

Sign (SIGN) is a decentralized protocol designed to bring verifiable digital signatures and attestations on-chain. It enables individuals and organizations to sign, verify, and manage agreements and credentials in a trustless, tamper-proof environment. What sets Sign apart is its focus on making on-chain attestations accessible and composable, allowing developers to build identity, reputation, and compliance tools on top of the protocol. Launched in 2025 and built on Ethereum, Sign serves as foundational infrastructure for Web3 applications requiring provable, permissionless verification across various use cases.
