# Privado ID

> Prove once, use everywhere.

Privado ID provides open-source middleware for privacy-preserving digital identity, letting developers integrate verifiable credential verification into applications using zero-knowledge proofs.

Privado ID helps developers and organizations add identity verification to applications without requiring users to expose personal data. Users can store W3C-compliant verifiable credentials in a self-sovereign wallet and share zero-knowledge proofs with applications and smart contracts. The platform follows the Iden3 protocol, supports EVM-compatible blockchains, and is available under open-source licenses with a self-hosted deployment option.

## Products

- [Privado ID](https://thegrid.id/profiles/privado_id): Privado ID is an open-source middleware for privacy-preserving decentralized identity. The platform enables organizations to issue W3C-compliant verifiable credentials and verify identity claims using zero-knowledge proofs, both off-chain and on-chain across EVM-compatible blockchains. Built on the Iden3 protocol, the toolkit includes an Issuer Node for credential issuance, a Verifier SDK for off-chain and on-chain verification, Wallet and JS SDKs for building identity wallet applications, and Schema and Query Builder tools. A web wallet and mobile application provide end-user interfaces for storing and presenting credentials. (Decentralised Identity, Live, Main Product)
- [Privado Identity Chain](https://thegrid.id/profiles/privado_id): Privado Identity Chain is a blockchain network serving as the primary chain for user identities in the Privado ID ecosystem. Operating with Chain ID 21000, it acts as the authoritative source of identity state, enabling other EVM-compatible chains to synchronize with it to prevent credential fragmentation across networks. DIDs created on the chain use the prefix did:iden3:privado:main:. (L1, Open Beta)
