Crypto Conversion Module for LynxMint

I have a series of .dox files that hold balances of electronic money. I need a clean, well-documented program that will read those files and instantly convert each balance into crypto—USDT, Bitcoin and Ethereum are mandatory, with Solana strongly preferred. The finished module has to run natively on the Lynx Mint operating system that powers my server.

You will receive the partial codebase I’m already using; treat it as a reference, not a constraint. Choose the language and libraries you’re most productive with as long as the final build installs smoothly on Lynx Mint and can be triggered from the command line or an API endpoint.

Timeline is tight: six to seven days from the project start.

Deliverables
• Source code with clear inline comments
• A setup script or concise install notes for Lynx Mint
• Demo data flow showing a .dox file fed in and crypto balances returned for USDT, Bitcoin, Ethereum (and Solana if implemented)
• Brief README outlining usage and any external dependencies

I’ll handle wallet keys and exchange access; your focus is the conversion logic and system integration. Let’s get this coded and running within the week.
