YFIN Code is a digital code marketplace selling 30 ready-to-use code packs across 5 categories: Chrome extensions, VS Code extensions, HTML/JS tools, WordPress plugins, and Tampermonkey userscripts. All purchases are made with $YFIN token (BEP-20 on BNB Smart Chain).

How do I install the Chrome extensions?

Download the ZIP file, extract it, then go to chrome://extensions in your browser, enable Developer mode, click Load Unpacked, and select the extracted folder. The extension is active immediately — no Chrome Web Store required.

How do I install VS Code extensions (.vsix)?

Open VS Code, go to the Extensions panel (Ctrl+Shift+X), click the ··· menu, select Install from VSIX, and pick the .vsix file. Works with VS Code, Cursor, and VSCodium. You can also run: code --install-extension filename.vsix

What is the $YFIN burn mechanic?

When you buy any code pack, 30% of the YFIN payment is sent to the burn wallet (0x000...dEaD) and permanently destroyed. The remaining 70% goes to the treasury. This reduces $YFIN supply with every purchase, making it deflationary.

What is the $YFIN token contract address?

The $YFIN token contract on BNB Smart Chain is: 0xF576bcFac0fefc2119f8b119e3a1ac1505F2FD45. Verify on BscScan: https://bscscan.com/token/0xF576bcFac0fefc2119f8b119e3a1ac1505F2FD45

Do the HTML/JS tools work offline?

Yes. All HTML/JS tools are self-contained — open index.html in any browser with no internet connection required. No server, no CDN, no external dependencies. Works forever after download.
