What is the TransGate Extension? Looking at zkPass Technology

The TransGate Extension is a gateway to zkPass’s privacy-preserving framework, enabling users to securely verify and transfer personal data from Web2 platforms to Web3 without compromising privacy. Powered by a hybrid stack of zero-knowledge proofs (ZKPs), MPC networks, and 3-party TLS protocols, TransGate brings trustless attestation into real-world applications.

If you're exploring the zkPass Schema Market or want to integrate your Web2 data into blockchain-based apps, understanding how TransGate works is essential.

Key Takeaways

• TransGate enables secure, private data attestations from any HTTPS-enabled Web2 platform.
  
   
• It leverages zkPass’s ZK + MPC tech stack, ensuring sensitive data remains private.
  
   
• Only install the TransGate extension via the official Chrome Web Store link for security.

What is the TransGate Extension?

The TransGate Extension is a Chrome-based plugin that allows users to interact with zkPass’s schema attestation system. This tool enables the generation of zero-knowledge proofs from HTTPS sources (such as banking, academic, or healthcare websites) without exposing the underlying data.

It functions as the front-end for zkPass Protocol, supporting verifiable credentials and data monetization without relying on centralized data providers.

How Does It Work?

The TransGate Extension is built on three core technologies:

• Zero-Knowledge Proofs (ZKPs): Cryptographic methods that prove a fact is true without revealing the fact itself.
  
   
• Multi-Party Computation (MPC): Ensures computations on encrypted data can be verified without sharing private inputs.
  
   
• 3-Party TLS Protocol: A privacy-preserving method for verifying HTTPS-sourced data in a decentralized fashion.
  
   

Step-by-Step Overview:

1. Install TransGate via Chrome Web Store – Always use the official source.
   
    
2. Connect your Web3 Wallet (e.g. MetaMask) to zkPass.
   
    
3. Choose a Schema in the zkPass Schema Market (e.g. income, education, credit score).
   
    
4. Generate a Zero-Knowledge Attestation from any HTTPS-compatible site.
   
    
5. Use the attestation to verify eligibility, gain access to services, or monetize your data—without ever revealing the raw data.

What is the zkPass Schema Market?

The zkPass Schema Market is a decentralized marketplace where users can:

• Select schemas (data types) to attest from Web2 platforms.
  
   
• Monetize their attestations by providing privacy-preserving proofs.
  
   
• Use proofs to access on-chain services such as DeFi platforms, DAOs, or KYC-less onboarding.

Developers can also create and publish schemas for others to use—paving the way for a new kind of data economy.

FAQs

Is TransGate safe to install?

Yes—as long as you install it from the official Chrome Web Store. Do not use third-party downloads to avoid potential risks or malicious versions.

What data can I attest with zkPass and TransGate?

You can attest any data available from HTTPS websites, such as academic credentials, salary slips, credit scores, or KYC-related data.

Do I have to share my private data with anyone?

No. zkPass uses zero-knowledge cryptography, so your data remains local and private while still generating verifiable attestations.
