# Self Protocol

Self is a **privacy-first, open-source identity protocol** built on **zero-knowledge proofs**. It lets developers verify real-world identity attributes — age, nationality, sanctions status, proof-of-human — without exposing personal data.

Self bridges the gap between real-world identity and on-chain activity. Users verify once with the Self app, then selectively disclose attributes across any application that integrates the protocol.

## Products

### Self Pass

Identity verification for applications. Verify that your users are real humans, meet age requirements, or pass sanctions checks — all without seeing their personal data. Supports passports, national IDs, Aadhaar, and KYC attestations from 60+ countries.

[Get started with Self Pass](https://docs.self.xyz/self-pass/self-pass)

### Self Connect

An open-source protocol that maps off-chain identifiers (phone numbers, email addresses, Twitter handles, GitHub usernames) to on-chain blockchain addresses. Enables users to discover and transact with each other using familiar identifiers instead of hex addresses.

### Self Agent ID

On-chain proof-of-human identity for AI agents. Each agent receives a soulbound ERC-721 NFT backed by a ZK passport verification, enabling trustless proof-of-human for autonomous agents. Implements the ERC-8004 standard with SDKs in TypeScript, Python, and Rust.
