First craft in 5 minutes
One inexpensive craft and six steps: what to buy, how to check the float, how to make the contract in the game and what to do with what drops. The numbers are an estimate at the prices of the latest collection, not a promise of profit.
The 2018 Inferno Collection + The Train 2025 Collection · Mil-Spec Grade
1What a trade-up is
A trade-up (trade-up contract) is a game feature: you give 10 skins of one rarity and get one skin of the next rarity — from the collection of one of the inputs. Which one drops is chance, but the odds are known in advance. More, with sliders, — How crafts work.
Risk. The game takes the inputs for good: a contract cannot be undone.
Next: what to buy ↓2What to buy
Buy exactly these items — of the right wear and with the float inside the “buy from–to” window. “Buy” opens the marketplace search with this window already set.

10 items in total — at the collected prices you invest 545.73 ₽.
Risk. Prices are from the last collection (07.10 03:02 MSK). If listings are dearer and the total comes to more than 545.73 ₽, the calculation no longer holds — do not keep buying blindly. Items bought on a marketplace arrive by trade and cannot go into a contract for 7 days.
Next: how to check the float ↓3How to check the float
Float is the item's wear number, from 0 to 1. Every input must have it inside the “buy from–to” window.
- On marketplaces the float is shown on every listing.
- On Steam — “Inspect in Game” on the listing, or the “Check floats on Steam” button on the craft page.
- Already bought: in the game “Inventory” → item → “Inspect” → the “i” icon at the bottom, the “Wear Rating” line.
Risk. One input outside the window — and the outcome drops with a different wear; the site's calculation no longer applies.
Next: the contract in the game ↓4How to make the contract in the game
- Open the “Inventory” and click any of the skins you bought.
- Choose “Use With Trade Up Contract”.
- Add all 10 — exactly the ones you bought. Check the names and wear.
- Sign the contract with the mouse and confirm — the new item appears in your inventory.
Risk. A signed contract cannot be undone, and an extra or wrong item changes the odds.

What to do with the outcome: sell it on the Steam Community Market — the money goes to your Steam wallet minus the 15% fee. Or on another marketplace — with its own fee and withdrawal terms; compare before selling.
Risk. “Every outcome pays off” holds at the collected prices. Prices move: while you buy and sell, the outcome may get cheaper.
Next: record the result ↓6Record the result
Write down what you bought and at what price, the float of the inputs, what dropped and what you sold it for. Send it using the template from the Tester's guide — this is how we fill Proven in practice: real crafts checked against what the site promised.
Risk. One craft is not statistics: both profit and loss in a single attempt are chance.
