Sign Protocol is an omni-chain attestation infrastructure designed to allow users, projects, and organizations to freely attest to claims and verify information across multiple blockchains. Instead of relying solely on centralized authorities, Sign Protocol provides decentralized tools and standards for creating verifiable attestations — digital “proofs” of assertions — in a way that’s accessible, interoperable, and transparent.

At its core, Sign enables a schema-registry system to standardize how attestations are structured, allowing for widely understandable, reusable attestations. Developers and users can choose whether data is stored fully on-chain, off-chain, or in hybrid architecture depending on their cost, permanence, or privacy needs. Key features include digital signatures, zero-knowledge proofs, and a data indexing layer (“SignScan”) for querying and exploring attestations.

The ecosystem is powered by the native SIGN token, which is used for governance, fees, and aligning incentives across the protocol. It supports applications including TokenTable (for token distribution, airdrops, vesting, etc.), EthSign (on-chain document signing), SignPass (identity verification and credentials), and tools for schema-management.

Sign Protocol’s use cases span digital identity, reputation and trust networks, credential verification (e.g. KYC/AML), verifiable on-chain contracts, proofs of ownership or credentials, whitelist/audit proofs, and more. Through its interoperable cross-chain design, Sign seeks to reduce fragmentation in verification across blockchains while offering developers a standard, composable framework for verifiable data.
