Sign[SIGN]
Sign is an omni-chain attestation protocol designed to enable secure, decentralized verification and sharing of digital credentials, identity claims, and token distributions across multiple blockchains such as Ethereum, Solana, and TON.
The protocol combines encryption, zero-knowledge proofs, and hybrid on-chain/off-chain data storage to facilitate privacy-preserving attestations that prove ownership, identity, or eligibility without exposing unnecessary information. SIGN provides four key products: Sign Protocol for cross-chain attestations, TokenTable for managing token distributions including airdrops and vesting, EthSign for legally compliant on-chain digital agreements, and SignPass for on-chain identity registration.
The SIGN token is the native utility token powering the ecosystem, used for creating and verifying attestations, governance participation, incentivizing developers, and securing network operations. Sign Protocol addresses challenges in digital trust such as cross-chain fragmentation, verification accessibility, and document authenticity, aiming to establish a universal standard for decentralized identity and credential verification.
