Frequently asked questions
How do I sell a Mann Co. Supply Crate Key for USDT?+
Paste your SteamID or Steam profile link, choose the quantity of Mann Co. Supply Crate Keys to sell, lock a quote for 30 seconds, and accept the trade offer in your Steam Mobile app. After the bot confirms receipt and settlement succeeds, USDT is credited to your site balance.
How much does SteamVaults take?+
SteamVaults spread starts at 2% and adjusts for volatility, liquidity, and inventory risk. A separate fixed $0.80 fee applies to Polygon withdrawals and is shown before you confirm.
Do you need my Steam password?+
No. SteamVaults uses your Steam Trade URL and Steam OpenID sign-in. You never share your Steam password, and items cannot move without your in-app confirmation.
Why is my trade held for 15 days?+
Steam may apply a hold of up to 15 days when an account is not protected by Steam Mobile Authenticator. Keeping it active for at least 7 days can avoid that standard hold, but item-specific or account-specific restrictions may still apply.
How do I withdraw the USDT?+
USDT settles to your site balance first. A Polygon wallet withdrawal is a separate request from My Page, and the fixed $0.80 fee is shown before confirmation.
