How do I start trading?

Sign in to the website using your Steam account and if you haven't already, go to p2p settings and paste your steam trade-link and steam api-key.
Choose the items you wish to sell from your inventory and choose its price for listing.
Choose the items you wish to buy from a marketplace — select an item and press buy.
Please be patient as the trade is being processed. Once completed, you will receive a trade offer on Steam containing the list of items you intend to trade.
Accept the trade offer through Steam.
Confirm the trade using the Steam mobile authenticator and enjoy your newly acquired items!
