Fees and Supported Networks
tf2cart currently supports USDT and USDC on BSC and Polygon. Buy invoices use the exact token and network shown. Withdraw shows the selected output, estimated fee, and received amount before confirmation.
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.

The active routes are USDT BSC, USDC BSC, USDT Polygon, and USDC Polygon. Always select the route in the interface and verify its token contract; a matching symbol on another network is not the same asset.
BSC token contracts
USDT BSC: 0x55d398326f99059fF775485246999027B3197955. USDC BSC: 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. BSC token amounts use 18 contract decimals in the payment scanner.
Polygon token contracts
USDT Polygon: 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Native USDC Polygon: 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Polygon token amounts use 6 contract decimals.
Buy invoice fees
USDT BSC is the direct treasury route and has no tf2cart processing fee. USDC BSC, USDT Polygon, and USDC Polygon invoices include the live conversion estimate plus protection equal to the greater of $0.05 or 0.045% of order value. The combined processing fee is shown before invoice creation; your wallet's sending gas is separate.
Payment confirmations
The current BSC and Polygon invoice response displays one required confirmation. Payment scanning prefers finalized chain state when the RPC supports it; otherwise it scans only through the configured confirmation depth. Detection time therefore depends on block production and RPC availability, not only the scanner interval.
Withdrawals
Withdrawals have no platform percentage markup. Direct USDT BSC shows the estimated token-transfer cost. Other routes can include conversion, protection, and destination transfer costs. The total estimate is deducted from the requested amount and shown before confirmation. A positive sub-cent estimate is represented as at least $0.01 because balances use cent accounting.
Common questions
What coins and networks are supported?
tf2cart supports USDT BSC, USDC BSC, USDT Polygon, and USDC Polygon for the current automated flows.
Which buy option has no tf2cart processing fee?
USDT BSC is the direct no-processing-fee purchase route. Alternative token or network routes show their conversion and protection cost before you create the invoice. Your sending wallet still pays its own network fee.
What happens if I send the wrong token or network?
Automatic detection expects the exact token, network, and amount shown. Sending the wrong asset or chain can delay or prevent automatic credit and may require support review.
Why do withdrawals show a processing fee?
Withdrawals require an on-chain token transfer from the tf2cart hot wallet. The withdrawal screen shows the estimated blockchain processing cost before confirmation and deducts it from the requested amount. Positive sub-cent estimates are represented as a minimum $0.01 charge because balances are handled in USD cents.
Does tf2cart charge a withdrawal percentage?
No percentage fee is added to normal withdrawals. Only the shown processing fee is deducted from the withdrawal amount.
