name: Polygon ID modified: 2026-06-14 description: > Polygon ID (now operating as Privado ID) is a self-sovereign identity platform that enables issuers to create and manage decentralized identifiers (DIDs) and verifiable credentials (VCs) using zero-knowledge proof cryptography. Built on the iden3 protocol and the Polygon blockchain, it allows organizations to issue privacy-preserving credentials — such as KYC attestations, age proofs, and reputation signals — while giving users full control over their identity data. Verifiers can authenticate users and gate access using ZK queries without learning underlying personal information. image: https://www.privado.id/img/logo.png tags: - Identity - Verifiable Credentials - Zero-Knowledge Proofs - Self-Sovereign Identity - Decentralized Identity - Blockchain - Web3 - KYC url: https://www.privado.id/ specificationVersion: "0.19" apis: - name: Polygon ID Issuer Node API description: > The Issuer Node REST API provides full lifecycle management of decentralized identities and verifiable credentials. Issuers use it to create DIDs on supported Polygon networks, issue and revoke credentials, manage credential schemas, handle wallet-based authentication flows via JWZ tokens, and publish identity state on-chain. The API also covers payment requests, display methods, and key management. image: https://www.privado.id/img/logo.png humanURL: https://docs.privado.id/docs/issuer-node/issuer-node-api/introduction/ baseURL: https://issuer-node-core-api-testing.privado.id tags: - Identity Management - Verifiable Credentials - Zero-Knowledge Proofs - DID - Credential Issuance - Credential Revocation - Authentication - Schemas - Payment - Key Management properties: - type: Documentation url: https://docs.privado.id/docs/issuer-node/issuer-node-api/introduction/ - type: OpenAPI url: https://raw.githubusercontent.com/0xPolygonID/issuer-node/main/api/api.yaml - type: GitHubRepository url: https://github.com/0xPolygonID/issuer-node - type: Swagger url: https://issuer-node-core-api-testing.privado.id/ - type: Plans url: https://github.com/api-evangelist/polygon-id/blob/main/plans/plans.yml - type: RateLimits url: https://github.com/api-evangelist/polygon-id/blob/main/rate-limits/rate-limits.yml - type: FinOps url: https://github.com/api-evangelist/polygon-id/blob/main/finops/finops.yml contact: - FN: Privado ID Support url: https://support.polygon.technology/support/solutions/82000473421 - FN: Privado ID GitHub url: https://github.com/0xPolygonID - FN: Privado ID Twitter/X url: https://x.com/PrivadoID - name: Polygon ID Verifier SDK description: > The Verifier SDK enables web2 and web3 applications to authenticate users based on verifiable credentials without accessing the underlying personal data. Verifiers compose ZK queries using the Query Builder, generate QR codes or Universal Links, and receive zero-knowledge proofs from user wallets.
