Welcome to X402DollarHomepage. This service is operated by SAS Catalytech, a French company (Société par Actions Simplifiée), which acts as the data controller for your personal information. When we refer to "we," "our," or "us" in this policy, we mean SAS Catalytech.
We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our pixel canvas service.

Transaction Data
We record pixel purchase transactions including: pixel coordinates, colors selected, timestamps, wallet addresses, and transaction amounts. This data is necessary to maintain the canvas and verify pixel ownership.

4. Payment Processing & Security
How Payments Work
We use the x402 payment protocol (HTTP 402 micropayments) for all pixel purchases. This protocol enables secure, gasless USDC transfers on the Base network. When you paint a pixel, you sign an EIP-3009 authorization that allows only the exact payment amount to be transferred - nothing more.
Payment Recipient
All pixel payments are sent to our verified wallet address:
0x0c1bca2283b125f78c1ade27dd260184e9ec2faf
You can verify this address on BaseScan.
What We Never Request
- Your seed phrase or Secret Recovery Phrase - NEVER
- Your private keys
- Unlimited token approvals
- Access to tokens other than USDC
- Permissions to transfer NFTs or other assets
USDC Contract (Base Network)
Payments use the official Circle USDC contract on Base:
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Verify on BaseScan.
