An onchain trading card game where your deck trades real markets.
Collect animal cards, build a deck, and compete in seasons of paper trading executed against the real SoDEX orderbook. Winners split the season prize pool — everything settled onchain in $SOSO.
🚧 In active development. This repo is the public overview. The core contracts, game engine and client live in a private repo until public launch — follow @NftraderCrypto for the reveal.
- Open a box → random animal cards across 4 rarities, drawn with onchain commit–reveal (no repeats per box)
- Build your deck → 1–5 distinct animals, each with a trading ability interpreted by the game engine
- Enter a season → your deck paper-trades against live SoDEX market data for the season window
- Climb the leaderboard → prize pool paid out onchain to the top players at season end
| Rarity | Examples |
|---|---|
| Common | Ram, Ant, Rooster, Fish… |
| Rare | Bull, Bear, Fox, Owl, Wolf |
| Epic | Shark, Octopus, Eagle, Turtle |
| Legendary | Whale, Dragon, Phoenix |
Onchain rarity is the source of truth for box odds and metadata; abilities are interpreted off-chain by the engine.
