ONE BEAST OF FLAME
MELTS TEN MEN OF STEEL

Depth-verified trade-ups, live price history, and a developer API — every CS2 edge in one place.

A CS2 trade-up contract converts ten skins of one rarity into one skin of the next rarity up — which output you can get depends on your inputs' collections, and its exact float is calculated from theirs, not guessed. CSAlpha prices every possible outcome against real CSFloat, DMarket, and Skinport listings, nets out marketplace fees on both sides of the trade, and shows the expected value and odds before you spend a single dollar.
