• Platform Fee: 2% of total pool
• Min Bet: 0.005 ETH
• Max Bet: 2 ETH per user per market
• One bet per user per market
• Winner payouts: Proportional to bet size within winning side

Payout Calculation Example

Total Pool: 10 ETH (6 ETH on YES, 4 ETH on NO)

If YES wins:

• Platform fee: 0.2 ETH (2%)
• Payout pool: 9.8 ETH
• User who bet 1 ETH on YES receives: (1/6) × 9.8 = 1.63 ETH
