Sign (SIGN) is the native token of the Sign Protocol ecosystem, which provides decentralized, verifiable identity, agreement, and ownership infrastructure for Web3. It powers applications like EthSign and TokenTable, offering tools for signing agreements, managing tokenized assets, and automating transactions in a fully decentralized environment. Sign Protocol combines off-chain data authentication with on-chain verification. It allows users to create binding agreements (e.g., contracts, signatures) and associate them with blockchain identities. These verifiable agreements can trigger smart contract interactions, ensuring a trustless bridge between legal commitments and decentralized applications. EthSign is one of the flagship products within the Sign ecosystem, enabling users to draft, sign, and manage agreements using decentralized identifiers (DIDs) and verifiable credentials. TokenTable complements this by offering cap table management and token issuance tools for startups and DAOs. The SIGN token is used across the ecosystem for governance, incentivization, and access to premium features. It underpins the decentralized verification services provided across EthSign, TokenTable, and future Sign Protocol applications. With a modular and developer-friendly architecture, Sign aims to build the foundational trust layer for Web3, merging legal enforceability with blockchain composability.
