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.

  - 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.

  - 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. Supports both off-chain verification (server-side) and on-chain
      verification via Polygon smart contracts.

    description: >
      The JS-SDK enables browser-based applications, extensions, and dApps to
      implement identity wallet functionality, create and manage DIDs, generate
      ZK proofs, and interact with the iden3 protocol directly. Supports
      credential storage, proof generation, and communication with issuer and
      verifier nodes.
