Value Calculation

function calculateTradeup(skins) {
  const totalValue = skins.reduce(
    (sum, skin) => sum + skin.value, 0
  );

  const bonusMultiplier = 1.15;
  const outputValue =
    totalValue * bonusMultiplier;

  return {
    input: totalValue,
    output: outputValue,
    profit: outputValue - totalValue
  };
}

Smart contract calculates fair value and adds a 15% bonus multiplier for successful tradeups.
