概述
ChainStream GraphQL 提供三个用于预测市场数据的 Cube，主要覆盖 Polygon。这些 Cube 覆盖预测市场从创建、交易到结算的完整生命周期。预测市场 Cube 位于 EVM 链组中，通常与
network: polygon 一起使用。PredictionTrades
近期预测市场交易
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 }
}
}
}
}
指定条件的交易
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 } }
}
}
}
按交易平台的成交量
query {
EVM(network: polygon) {
PredictionTrades(
marketplace: {is: "Polymarket"}
limit: {count: 100}
orderBy: {descending: Block_Time}
) {
