This website offers you an automated Team Fortress 2 banking service for weapons, hats, keys and many other items.

You can bank your TF2 items for metal or you can exchange your metal for TF2 items our bots have in stock.

On top of banking we also offer tf2 item auctioning and giveaways/raffles and have an active community

Scrap.TF uses Steam's official OpenID interface to authenticate your Steam account. In this process you sign in with your username and password on the Steam servers, after that the Steam server tells us if you logged in successfully and returns your 64bit Steam ID. Your user credentials will not be shared.
