How tf2cart Works
tf2cart coordinates Steam Trade Offers, supported stablecoin payments, stock, payout liquidity, and website balance through one tracked order flow.
tf2cart is independent and is not affiliated with Valve or Steam. Steam sign-in uses official Steam OpenID on steamcommunity.com; tf2cart never asks for your Steam password.
Open exchange1. Sign in through Steam
Sign-in opens official Steam OpenID on steamcommunity.com. tf2cart receives your Steam identity and public profile details, never your Steam password. Save a current Steam trade URL before buying or selling.
2. Choose buy or sell
The exchange loads the current key prices, available bot stock, your website balance, and sell payout capacity. Select a key quantity, token, and network. The server validates the final request rather than trusting browser calculations.
3. Buying reserves keys
A buy order checks stock under a concurrency lock and reserves the requested keys so another active invoice cannot sell the same stock. Existing website balance is applied first; only the remaining value becomes a crypto invoice.
4. Pay the exact invoice
The invoice states one token, one network, the receiving address, an exact amount, and a 15-minute expiry. Send that exact amount without rounding. Your wallet's own sending-network fee is separate from the invoice amount.
5. Payment detection and confirmation
The scanner matches the receiving wallet, token contract, network, raw transfer amount, and active invoice. The current interface displays one required confirmation; the scanner uses finalized chain state when the connected RPC supports it and otherwise applies its configured confirmation depth.
6. Steam buy delivery
After supported payment settlement, the buy order moves to Steam delivery without waiting for background treasury conversion. The bot sends one tracked offer to your saved trade URL. You have 15 minutes to review the sender, item count, and accept.
7. Selling reserves payout liquidity
A sell order validates your visible tradable key count and the chosen coin/network payout capacity. Pending sells reserve that route's liquidity. The bot sends a tracked offer, and website balance is credited only after Steam confirms the keys arrived.
8. Withdrawals and swaps
Website balance can be withdrawn or swapped through supported routes. The preview shows processing and service fees before confirmation. Funds remain locked while a withdrawal or swap is pending so the same balance cannot be spent twice.
9. Cancellations and failures
Cancelling an unpaid invoice releases reserved keys. Unaccepted sell offers release payout reservations without crediting balance. Definitively failed buy delivery returns paid order value to website balance. Uncertain Steam or blockchain states remain under review until duplicate delivery or refund risk is resolved.
10. History and support
Order, invoice, Steam offer, withdrawal, swap, and ledger states are retained for reconciliation and shown in account history where applicable. Contact support with the order ID, Steam offer ID, token, network, exact amount, and transaction hash when a state needs review.
