Sign Protocol

Sign Protocol is an omni-chain attestation protocol that lets anyone create and verify claims on-chain. It standardizes trust data so people, apps, and contracts can attest to facts (credentials, events, agreements) and have those attestations be portable across chains. Developers define reusable schemas, then write attestations that any verifier can check.

Under the hood, attestations are digitally signed structured data tied to a registered schema and stored either on-chain or via durable storage like Arweave/IPFS. They're retrievable through GraphQL and SDKs, and manageable in the Sign app (create/explore schemas, issue or inspect attestations). This combination of schema registry, on- and off-chain storage, and open APIs enables trust data to be verifiable, queryable, and composable across ecosystems.
