Polygon ID

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.

- 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.

  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.
