概要

ChainStream GraphQL は予測市場データ用に 3 つの Cube を提供しており、主に Polygon で利用できます。これらの Cube は、予測市場のライフサイクル全体（作成・取引・決済）をカバーします。
Prediction Market Cube は EVM Chain Group で利用できます。主に network: polygon と組み合わせて使います。

​
PredictionTrades

​
直近の予測市場取引

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

​
特定の Condition に紐づく取引

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

​
マーケットプレイス別の取引量

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

​
PredictionManagements

​
市場の作成・決済イベント

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

​
イベントタイプで絞り込み

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

​
PredictionSettlements

​
直近の決済

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

​
特定の Holder の決済

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