- What is a CS2 trade-up contract?
- A trade-up contract in Counter-Strike 2 lets you exchange 10 skins of the same rarity for one skin of the next higher rarity. The outcome depends on the collections your input skins come from and their float values. SkinGrind scans thousands of possible contracts to find the most profitable ones.
- How does the scanner find profitable Trade Ups?
- The scanner refreshes CSFloat prices hourly, then walks every contract combination it can build from them. For each one it works out the float ceiling each input has to stay under, the outcome pool and its probabilities, and the expected value after the marketplace fee. Contracts whose expected value beats what the inputs cost are the ones listed here.
- Can I build my own CS2 Trade Up contract?
- Yes. The CS2 Trade Up calculator lets you pick the 10 input skins yourself, set their floats, and see the outcome odds, the output float and the expected profit for a contract the scanner did not pick. Use the scanner to find contracts, and the calculator to price one of your own.
- What determines trade-up contract outcomes in CS2?
- Outcomes are determined by two factors: the collections your input skins belong to (which decide the possible output skins) and the floats of your inputs (which determine the wear condition of the output). Each input float is normalized inside its own skin's float range before the average is taken, and that average is then scaled into the output skin's range. Each possible outcome has a probability based on how many inputs come from each collection.
- What is an anchor skin in a trade-up?
- An anchor skin is the primary input skin that defines a trade-up contract. It determines the collection and rarity tier, which controls what output skins are possible. SkinGrind groups trade-ups by anchor skin so you can quickly compare all contracts built around a specific input.
- Are CS2 trade-up contracts profitable?
- Some trade-up contracts have a positive expected value, meaning they are profitable on average over many attempts. However, each individual contract is probabilistic, so you can still lose money. SkinGrind helps you find contracts with the best odds and highest expected profits.
