What is Self Protocol Identity Verification?
The Self Protocol skill enables developers to integrate advanced, zero-knowledge identity verification into their applications. By leveraging the self.xyz protocol, this Openclaw Skills integration allows users to prove attributes like age, nationality, or humanity via NFC-scanned documents without revealing their actual identity.
This skill is an essential tool for developers building decentralized applications, fintech platforms, or any service requiring high-assurance KYC and Sybil resistance. It bridges the gap between real-world identity documents and digital privacy, making it a cornerstone of modern Openclaw Skills implementations.
Self Protocol Identity Verification Use Cases
- Adding privacy-preserving KYC or age verification to Next.js applications.
- Implementing Sybil resistance for airdrops or governance on the Celo blockchain.
- Verifying user nationality or OFAC compliance without storing sensitive document data.
- Creating trustless, on-chain identity gates using Self Protocol smart contracts.
How Self Protocol Identity Verification Works
- Initialize the SelfAppBuilder on the frontend to define required disclosures like minimum age or nationality.
- Generate a secure QR code using the SelfQRcodeWrapper which users scan with the Self mobile app.
- The Self app utilizes the document's NFC chip to generate a zero-knowledge proof (ZKP) of the requested attributes.
- The proof is sent to a backend endpoint or a Celo smart contract for validation.
- The SelfBackendVerifier or on-chain contract confirms the proof's validity without ever seeing the raw document data.
Self Protocol Identity Verification Setup
Install the necessary packages using npm:
npm install @selfxyz/qrcode @selfxyz/core
Configure your frontend with the SelfAppBuilder and provide a publicly accessible endpoint for the Self app to send proofs. When using Openclaw Skills for development, ensure your local environment is exposed via a tunnel for testing.
Self Protocol Identity Verification Data Schema & Taxonomy
| Parameter | Type | Description |
|---|---|---|
| appName | string | The display name shown to the user in the Self app. |
| scope | string | A unique identifier for the verification context. |
| disclosures | object | Defines required proofs such as minimumAge or nationality. |
| endpointType | string | Destination type: https, https-staging, celo, or celo-staging. |
| userId | string | A hex-encoded unique identifier for the user. |
Self Protocol Identity Verification Advanced Features
- Deep linking support for seamless mobile-to-mobile identity verification workflows.
- On-chain verification by inheriting the SelfVerificationRoot contract on Celo for trustless apps.
- Custom verification hooks to execute specialized logic upon successful identity proofing.
- Mock passport support for rapid development and testing without requiring real documents.
- Anti-replay protection using Poseidon-hashed scopes to secure multi-contract environments.
