Introduction

x402WALL ("we," "our," or "us") respects your privacy. This Privacy Policy explains how we collect, use, and protect information when you use our pixel marketplace service built on Solana.

Information We Collect

Wallet Information

When you connect your wallet, we collect your public wallet address. This is necessary to process transactions and display your pixel ownership. We do not have access to your private keys or seed phrases.

Transaction Data

All transactions are recorded on the Solana blockchain, which is public by design. This includes pixel purchases, sales, and content updates. We store references to these transactions to display ownership and history.

Content You Upload

Images, titles, and links you add to your pixels are stored on our servers and displayed publicly on the wall. This content is associated with your wallet address.

Technical Data

We may collect standard technical data such as IP addresses, browser type, and device information for security, analytics, and service improvement purposes.

Blockchain and Public Data

Please understand that blockchain transactions are permanent and publicly visible. Your wallet address and transaction history on Solana cannot be deleted or hidden. This is fundamental to how blockchain technology works.

Content displayed on your pixels is also publicly visible to all visitors of x402WALL.
