Jervis: Trading & Market Assistant

The official, secure, and lightning-fast trading companion for the Jervis.gg marketplace.

The official trading companion for the Jervis.gg marketplace. Jervis Trade Assistant connects your Steam account to Jervis.gg so that P2P trades are faster and safer. It sends and checks trade offers for your Jervis orders, keeps your inventory up to date and warns you about common Steam scams, all from your browser. 🛡️ CORE FEATURES • Verified Auto-Accept Before accepting an incoming trade offer, the extension compares it with your Jervis order: the items, the seller and the offer details. An offer is accepted automatically only when it matches. If it doesn't match (for example the offer asks for your items or contains the wrong item), it is never accepted and the attempt is reported to Jervis. When a match can't be confirmed, the offer is left for you to review and accept on Steam yourself. You can turn Auto-Accept off at any time; you then accept every trade manually on Steam. • Auto-Send When you sell an item on Jervis.gg, the extension prepares and sends the trade offer to the buyer in the background. Outgoing items ALWAYS require your own Steam Guard Mobile confirmation. You can turn Auto-Send off and send trades from Jervis.gg or the Steam website instead. • Scam Shield On Steam trade offer pages, every offer is checked against the Jervis order database. A green banner marks a verified Jervis trade, and a red banner warns you about a suspicious or tampered offer before you accept anything. • Steam API Key Alert The extension checks whether your Steam Web API key is registered to an unknown domain, which is a common sign of an API scam, and warns you to revoke the key immediately. • Background Inventory Sync Your CS2 inventory details (float values, paint seeds, stickers, charms) are synchronized with Jervis.gg every 5 minutes, so you don't need to keep a Steam tab open. • One-Click Selling List items on Jervis.gg directly from your Steam inventory page using the quick-action buttons. • Market Price Insights While browsing the Steam Community Market, see Jervis.gg prices next to Steam prices. • Clear Status at a Glance The popup shows whether you are connected, which automations are on, when the last check ran, how many trades were accepted and how many are waiting for your review. 🔒 PRIVACY & SECURITY Jervis Trade Assistant works only between your browser, Steam and Jervis.gg. It uses your existing Steam session locally to carry out trades you created or approved on Jervis.gg. Your Steam password, login cookies and access tokens stay in your browser and are never sent to Jervis or anyone else. The only data sent to Jervis.gg is what the service needs: your trade offer status and your CS2 inventory item details. No data is sold or shared with third parties.
