I want a small, self-contained PHP script with a browser-based GUI that sits on my Linux server and lets me swap my own ERC-20 token (the one I already hold in MetaMask) for ETH on the Ethereum Mainnet. The interface should: • Detect the connected MetaMask wallet, display the token balance, and let me enter how many tokens to convert. • Allow me to define and later update the conversion price (token-to-ETH rate) from a simple settings panel so I can run private sales without touching the code. • Build and sign the transaction client-side via MetaMask, then broadcast it so the user receives ETH back to the same wallet once the swap succeeds. • Show clear status and Tx hash feedback while the transaction confirms. Please keep the script focused on this single token only—no multi-token framework is required—yet structure it cleanly so I could extend it myself later if needed. I’ll provide the token contract address and any additional endpoints you might require (e.g., Infura). Deliverables are: 1. The PHP files and front-end assets. 2. A short README describing server prerequisites, environment variables, and how to adjust the price setting. 3. Brief install steps tested on a standard LAMP stack. If you rely on [login to view URL], [login to view URL], or similar libraries, bundle or document the exact versions so everything runs smoothly on deployment.

Greetings, I see you’re looking for a PHP script with a user-friendly GUI to swap your ERC-20 token for ETH directly on your Linux server. This is a solid project, and I can help you create a streamlined interface that connects to your MetaMask wallet, shows your token balance, and facilitates the conversion process without needing to dive into the code for updates. I'll ensure that the script only focuses on your specific token while making it easy for you to adjust the conversion rate via a simple settings panel. The transaction process will be handled client-side through MetaMask, providing clear feedback throughout. I’m familiar with the required technologies, which will allow me to create a clean and maintainable solution for you. Best regards, Muhammad Arshman

Technically, the smartest move for your project is to build a clean PHP script with a dedicated front-end using web3.js. This will allow the MetaMask integration for wallet detection and transaction signing. I can have the initial version ready in 5 days, including the GUI and documentation for setup. Say the word and I'll have a first version in front of you fast.
