Payout mechanism

How winning, losing, and the prize pool work.
Every round takes 1 minute: 30 seconds to place your prediction, then 30 seconds to watch and see how close the price lands. You set a target (green line) for where you think the price will be when the round ends, then watch the live price (orange line) to see how close you got. Unlike yes/no markets like Polymarket or Kalshi, there’s no side to pick, just your best prediction of the number.
Placing a prediction during the 30s PREDICT phase. User picks an exact number.

Once predictions lock, the watch phase begins. Trepa shows you a live payout curve and a payout amount that updates in real time as the price moves. The closer the price gets to your target, the bigger your payout.
The price can still move before the round ends. The green shaded area is your profitability range, where you're currently beating the round's median and on track to win.

Small improvements near your target matter more. Closing the gap at the end can meaningfully increase your payout, or flip you from losing to winning. Each round has a median error cutoff: beat it and you win your stake back plus a share of the prize pool by accuracy, miss it and you lose your entire stake.
