SIGN (the native token of the Sign / EthSign / Sign Protocol) powers a universal attestation and credential verification infrastructure. Its core utility lies in facilitating the creation, storage, and verification of digital attestations (statements of fact, identity claims, document signatures, etc.) across different blockchains.
It’s used for governance, network operations, and paying for attestation-related services within the ecosystem. The Sign ecosystem comprises tools like EthSign (on-chain document signing), TokenTable (token distribution / vesting), Schema Registry (standard formats for attestations), and SignPass (on-chain identity) to provide a full stack around digital trust.
