Trade Up: CS2 Contracts

🧮 Trade Up CS2 — a contract desk for Counter-Strike 2 trade-ups: fill 10 slots, read outcome percentages, simulate a roll.

Traders check contract EV before burning inventory on Steam or the market. Trade Up CS2 helps you plan: pick a rarity, add ten skins from the bundled catalog, and see collection-weighted chances for the next tier — with skin previews. Unofficial helper, bilingual EN/RU, no Steam login.

🔊 How it works
1️⃣ Choose input rarity (Consumer → Covert)
2️⃣ Fill 10 slots (search or Random 10)
3️⃣ Read next-tier outcome % list
4️⃣ Tap Simulate roll to sample one result

⚠️ Odds follow **collection-weighted trade-up logic** and may differ from a live Steam contract. Float mapping is approximate. This app never trades real skins.
