ℹ️

When allowing users to place express (or combo) bets, you can pass multiple selections, each for different outcomes across various events, and combine them into one larger bet.

const {...} = usePrepareBet({
  betAmount: '10',
  slippage: 5,
  affiliate: '0x...',
  selections: [
    {
      conditionId: '486903008559711340',
      outcomeId: '29',
      coreAddress: '0x34nsf41f...',
    },
    {
      conditionId: '486903008559711341',
      outcomeId: '30',
      coreAddress: '0x34nsf41f...',
    },
  ],
  odds,
  totalOdds,
})
ℹ️

To perform batch bet you need to provide object with amounts for each selection, key is concatenation of conditionId and outcomeId:

const {...} = usePrepareBet({
  betAmount: {
    '486903008559711340-29': 1,
    '486903008559711341-30': 10,
  },
  slippage: 5,
  affiliate: '0x...',
  selections: [
    {
      conditionId: '486903008559711340',
      outcomeId: '29',
      coreAddress: '0x34nsf41f...',
    },
    {
      conditionId: '486903008559711341',
      outcomeId: '30',
      coreAddress: '0x34nsf41f...',
    },
  ],
  odds,
  totalOdds,
})
