CS:GO / CS2 Trade-Up Contract — Complete Guide
Trade-up contracts have been a core feature since CS:GO and continue unchanged in CS2. Whether you're a veteran CS:GO trader or new to CS2, the mechanics are identical — 10 skins in, 1 skin out. Here's the complete guide.

When CS:GO became CS2 in September 2023, the trade-up system stayed exactly the same:
- ✅ Same float formula
- ✅ Same rarity tiers
- ✅ Same collection mechanics
- ✅ Same StatTrak rules
- ✅ Same 10-input requirement
What DID change: new collections were added (CS2-exclusive cases), some old collection prices shifted, and the overall skin economy grew significantly. All CS:GO trade-up knowledge still applies — you just have more collections to work with.
Why People Search 'CSGO Trade-Up Contract'
Many traders still use the term "CS:GO trade-up" because:
- Most YouTube tutorials and guides reference CS:GO
- The system was popularized during the CS:GO era
- Older collections (CS:GO-era cases) are still the backbone of many profitable trade-ups
Whether you call it CS:GO or CS2, the trade-up contract system is identical. TradeUpX supports all collections from both eras.
The Basics of Trade-Up Contracts
A trade-up contract exchanges 10 skins of one rarity for 1 skin of the next higher rarity. Key mechanics:
- Select exactly 10 skins of the same rarity tier
- The game produces 1 output skin from the next tier up
- Output is randomly chosen from all possible next-tier skins in the input collections
- Output float is determined by the average input float formula
- StatTrak inputs produce StatTrak output
The skill is in choosing inputs where the expected output value exceeds the input cost. That's what TradeUpX calculates for you.
