Introduction

Welcome to the official vouch documentation. This guide will help you understand how vouch works and how to integrate it into your application.

What is vouch?

vouch enables businesses to verify user claims without touching the underlying private data. Our platform allows individuals to generate verified attestations directly from their devices, without sharing sensitive information or requiring complex or expensive API integrations.

Understanding the Problem

Online businesses face challenges when handling private user data:

• Sensitive Data Management: Processing personal data creates obligations under privacy laws, increases IT costs, and exposes you to breach risks.
• API Limitations: Integrating with multiple platforms can be painful, expensive, and often impossible when APIs aren't available. You might also run into deplatforming risk if your operation poses a competitive threat to an incumbent platform.
• Verification Scalability: Traditional verification methods slow down operations and create friction that users hate.

vouch powered by vlayer Web Proofs

vouch leverages vlayer Web Proofs as the market leading implementation of zkTLS to facilitate its core value proposition. Importantly, vouch has been structured so that you don’t need to be a web3 business (run smart contracts) to benefit from this technological primitive. As long as your app runs on a server and can communicate with an API, you are good to go.

Implementation Overview

1. Create a business account with vouch to start receiving verifiable user claims.
2. Configure claim requirements based on your verification needs.
3. Integrate vouch into your application flow with our API. Test and go-live.
4. Receive attestations when users complete the verification process.

Vouch operates across multiple end-user platforms:

• Mobile: Native application for iOS and Android.
• Web: Browser extension for desktop environments.
