How it works

Four steps from sign-in to keys in your Steam inventory

Step 1
Sign in with Steam
One-click sign-in via Steam OpenID. After signing in, add your trade URL — without it bots can't send you keys.
Step 2
Top up your balance
Deposit USDT on the BSC or TON network — we'll give you an address and the exact amount. Funds usually arrive within 1–2 minutes after the transaction is confirmed.
Step 3
Buy keys
Two ways:
- Instantly — take from the order book at the best price
- Cheaper — place your own limit-bid order and wait for matching sellers
Step 4
Claim them in Steam
Purchased keys accumulate in your storage. Request a withdrawal — a bot sends a trade in Steam. Or keep them to resell on the exchange

TF2 Key Exchange in USDT — Buy and Sell Mann Co. Supply Crate Keys

TF2key is an order-book marketplace for Team Fortress 2 keys, complete with a live order book, price charts, and instant execution. Buy and sell Mann Co. Supply Crate Keys for the USDT stablecoin on the BSC and TON networks. Sign in through official Steam OpenID; deposit and withdraw funds via crypto wallets.

Buy TF2 keys

Two ways to trade. “At market” — keys arrive instantly from the best seller offers in the order book. “Cheaper” — set your own limit-bid price and wait for a matching seller. Every key you buy stacks up in your storage — withdraw it to Steam via the bot or resell it right on the exchange.

Sell TF2 keys for USDT

USDT lands in your balance the moment the trade executes, with no delays.

Live order book and price history

Frequently asked questions

›What is a Mann Co. Supply Crate Key?

The Mann Co. Supply Crate Key is a cornerstone item of the Team Fortress 2 economy.

Originally needed to open TF2 crates, it grew into a universal unit of trade within the community. Keys are used to value items, make trades, buy and sell skins, and as a convenient way to move value into and out of the Steam ecosystem through third-party platforms.

Thanks to high liquidity, steady demand, and large trade volume on the Steam Community Market, TF2 keys are considered one of the most popular and convenient items to trade.

›How is an exchange different from a regular marketplace?

On a regular marketplace a price is just a listing; you have to wait for someone to buy your specific lot. An exchange runs on an order book: the best prices are visible instantly and orders fill automatically through order matching, without action from the seller or buyer.

›How much is a TF2 key in USDT?

The price floats — watch the order book and the chart on the home page. Best ask and best bid are shown in the market header, with the historical chart below.

›How do I withdraw purchased keys to Steam?

Go to “Profile” → “Storage” and click “Withdraw”. The bot sends a trade-offer to your Steam — confirm it, and the keys land in your inventory.

›Can I sell keys without a trade URL?

No. A trade URL is what lets our bot accept your keys. You can get the URL in Steam: “Inventory” → “Trade offers privacy settings”.
