You can review the basics of player-to-player trading here and our take on trading that happens outside the game here.

Trading Tips:
Crates, Keys, and other in-game items may only be traded for other in-game items, Crates, or Keys. Trading outside of the game (For money or other goods) is against our EULA and Terms of Service

Remember that without proper precautions taken, there is a chance that a legitimate player-to-player trade ends up badly for one of the sides, and here's where we'd like to give a little helping hand with a few pointers on trading best practices. As they say, prevention is the best cure:

• Pay close attention to the items that you are being offered. Highlight each of them individually, so that you know that you're being offered what was agreed upon.
• If your trade partner offers more items than what was agreed upon, that's a red flag! Nobody would want to end up on a losing side of a trade, so there should be no reason for them to do so! Always make sure the items you were originally offered are still there and were not removed
• When possible try to trade with people you know.
• Getting a 3rd person involved can also be a red flag. If building trust is the argument invoked, then play a few more games with that person, do some "warm-up" trades with less valuable items, get to know them a bit better, before engaging in trading with the more valuable ones. Remember, there will always be someone wanting what you have to offer and vice-versa, there is no point in rushing things by getting a middleman involved.

Remember! It is the responsibility of all players to ensure that a trade is fair and equitable before accepting the trade. Our support team cannot intervene in trades.
