The setup Two players put up equal bets in SOL or USDT. Each gets a virtual $1,000 to trade real SOL, BTC and ETH prices. When both windows close, the higher final balance takes the pot, minus a flat 1%.
Play on your own clock Once matched, you have 24 hours to make your first trade, and that trade starts your window. Your opponent's window starts with their first trade, also within 24h. Both windows are the same length (the creator picks anything from 5 minutes to 72 hours), but they don't need to overlap. You never wait for your opponent to be online.
Sealed trades Only a fingerprint (hash) of each trade goes on-chain. Your opponent can't see your positions, your profit or even which coin you traded until both windows have closed. Nobody can copy you.
You fill at the next price When you trade, you don't get the price on your screen. You get the first price published after your trade lands. That blocks a classic exploit: signing a trade, waiting to see where the market goes, and only confirming if it went your way.
No leverage, no liquidations A long can only lose what it cost. A short reserves its full value as margin. Your balance can never go below zero.
Real prices Live prices anchored to Pyth, Solana's on-chain price oracle.
The close Trading stops 10 seconds before your window ends.
How a duel ends 🏆 Higher balance wins the pot (minus 1%) 💤 One player never traded? The one who did wins. Sitting out can't force a draw. 🤝 Neither traded? Both bets come back, minus 1% ↩️ Nobody joined? The creator can claim back their full bet, no fee.
No spread. No trading fees. One flat 1% on the pot. And every duel farms you $JACK, win or lose.
