What is the x402 Trust Center?

Overview

The x402 Trust Center is a decentralized reputation system that helps build trust and transparency across the FREGO and broader x402 ecosystem. By aggregating user ratings and transaction data, the Trust Center enables informed decision-making when interacting with merchants and service providers on the x402 protocol.

What is it?

The x402 Trust Center collects and analyzes ratings from real x402 protocol transactions to create transparent reputation scores for merchants. Every rating is tied to a verified blockchain transaction, ensuring authenticity and preventing manipulation. This creates a trustworthy foundation for users to evaluate merchants before engaging with their services.

Key Features

• Transaction-Verified Ratings - Every rating must reference a real blockchain transaction, ensuring authenticity

• Public and Transparent - No authentication required to submit or view ratings

• Spam Prevention - Each blockchain transaction can only be rated once

• Real-Time Processing - Transaction details are enriched asynchronously after submission

• Dynamic Scoring - Merchant scores are recalculated hourly based on accumulated ratings

• Ecosystem-Wide - Works across all x402 merchants, not just FREGO

Why This is Useful

• Quality Assurance - Maintain high standards across the x402 merchant network through community feedback

• Informed Decisions - Choose reliable merchants based on verified transaction history and peer ratings

• Merchant Accountability - Encourage excellent service through transparent reputation tracking

• Trust Building - Enable merchants to build credibility through consistent positive ratings

• Network Effects - As more users rate transactions, the system becomes increasingly valuable for everyone

How It Works

1. A user completes an x402 protocol transaction with a merchant

2. The user submits a rating using the Merchant Rating API, providing the transaction hash and their wallet address

3. The system verifies the transaction exists on the blockchain

4. The rating is processed and the merchant's reputation score is updated

5. Other users can view merchant scores to make informed decisions

The Merchant Rating API

The Trust Center exposes a public API that allows anyone to submit ratings for x402 transactions. The API requires no authentication, making it easy for developers to integrate rating functionality into their applications, AI agents, or workflows.

To submit a rating, you'll need:

• The blockchain transaction hash from your x402 transaction

• Your wallet address (the address that initiated the transaction)

• The resource endpoint that was called (e.g., /api/v1/generate)

• Your rating decision (thumbs up or thumbs down)
