About this extension
Stop counting scrap manually and trade safer! 🍌

Nano Trade Assistant is a lightweight tool designed to make Team Fortress 2 trading faster and secure. It automates the boring math and protects you from common scams.

⚡ KEY FEATURES:

Auto-Calculator: Instantly sums up Keys, Refined, Reclaimed, and Scrap metal in any Steam Trade Offer window. No more calculators!

Smart Price Check: Displays the real Backpack.tf price directly on the trade button.

Scam Protection: The border turns GREEN if the price matches the listing, or RED if the values don't add up (protecting you from "quick-switch" scams or bad math).

One-Click Fill: Automatically adds the exact amount of metal/keys to the trade window with a single click.

🔒 PRIVACY & SECURITY:

No API Key Required: We never ask for your Steam API Key.

No Login Required: Works directly in your browser.

No Data Collection: We respect your privacy. This extension does not track you or send data to external servers.

Designed by a trader, for traders. Verified on Chrome Web Store and now available on Firefox.
