MarketApp P2P

MarketApp P2P is the official extension for the Market.CSGO marketplace, designed to facilitate safe and fast item sales through a peer-to-peer (P2P) system. Extension Features: Basic Integration with Steam API The extension retrieves basic information from your Steam profile for display, as well as information from other users profiles for P2P trades on the trade offer page. Creating and Accepting Trade Offers via Steam API The extension allows users to create and accept trade offers on Steam that are initiated by Market.CSGO. Depending on the settings, this process can be either manual or automatic. Note that the extension does not handle trade confirmations. You will need to use the official Steam app, the MarketApp, or the Market.CSGO mobile app to confirm trades. Steam Trade Offer Page This page features a custom interface that distinguishes Market.CSGO trade offers from other offers. It also provides the ability to manually create and confirm trade offers from Market.CSGO. CS2 Game Inventory Page on Steam The appearance of the inventory page for CS2 items has been enhanced, with added features such as displaying the Float value and showing trade restrictions for items. For convenience, quick-sell and instant-sell buttons have been added for selling items on the Steam marketplace. The top toolbar has also been redesigned with a “Multiple Item Sale on Steam Marketplace” feature, which allows users to select multiple CS2 inventory items and sell them at a specified price. Steam Market Page The extension enhances the Steam Community Market page with advanced trading tools and market analytics. The module provides three main sections: Active Lots for managing your buy and sell orders with price deviation warnings, Steam Market Trade for browsing popular items, new listings, and recently sold items with search functionality, and Market History for viewing your complete trading history with filtering options and CSV export. Users can create buy orders, list items for sale, remove listings, and cancel buy orders directly from the enhanced interface, with real-time price updates and trade volume information displayed for better trading decisions.
