概述

ChainStream GraphQL 提供三個預測市場資料 Cube，主要在 Polygon 上使用。這些 Cube 覆蓋預測市場的完整生命週期 — 從建立、交易到結算。
預測市場 Cube 屬於 EVM Chain Group，主要配合 network: polygon 使用。

​
PredictionTrades

​
近期預測市場交易

query {
  EVM(network: polygon) {
    PredictionTrades(
      limit: {count: 20}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Transaction { Hash }
      Trade {
        Buyer
        Seller
        Amount
        Price
        Fee
      }
      Prediction {
        Condition { Id Outcomes }
        Question { Id }
        Outcome
        Marketplace { ProtocolName }
      }
    }
  }
}

​
特定 Condition 的交易

query {
  EVM(network: polygon) {
    PredictionTrades(
      conditionId: {is: "CONDITION_ID"}
      limit: {count: 50}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Trade { Buyer Seller Amount Price }
      Prediction { Outcome OutcomeToken { SmartContract } }
    }
  }
}

​
按 Marketplace 統計交易量

query {
  EVM(network: polygon) {
    PredictionTrades(
      marketplace: {is: "Polymarket"}
      limit: {count: 100}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Trade { Amount Price }
      Prediction {
        Question { Id }
        Marketplace { ProtocolName }
      }
      count
      sum(of: Trade_Amount)
    }
  }
}

​
PredictionManagements

​
市場建立與解析事件

query {
  EVM(network: polygon) {
    PredictionManagements(
      limit: {count: 20}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Transaction { Hash }
      Management {
        EventType
        Description
        Group
        Prediction {
          Condition { Id }
          Question { Id }
          Marketplace { ProtocolName }
        }
      }
    }
  }
}

​
按事件型別過濾

query {
  EVM(network: polygon) {
    PredictionManagements(
      eventType: {is: "ConditionResolution"}
      limit: {count: 20}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Management {
        EventType
        Description
        Prediction { Condition { Id Outcomes } }
      }
    }
  }
}

​
PredictionSettlements

​
近期結算

query {
  EVM(network: polygon) {
    PredictionSettlements(
      limit: {count: 20}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Transaction { Hash }
      Settlement {
        EventType
        Holder
        OutcomeTokenIds
        Amounts
        Prediction {
          Condition { Id }
          CollateralToken { SmartContract Symbol }
          Marketplace { ProtocolName }
        }
      }
    }
  }
}

​
特定持有者的結算

query {
  EVM(network: polygon) {
    PredictionSettlements(
      holder: {is: "0xHOLDER_ADDRESS"}
      limit: {count: 50}
      orderBy: Block_Time_DESC
    ) {
      Block { Time }
      Settlement {
        EventType
        Amounts
        Prediction { Condition { Id } }
      }
    }
  }
}
