Entities

This subgraph exposes five entities:

1. MarketContract
2. PositionToken
3. PositionTokenMintedEvent
4. PositionTokenRedeemedEvent

MarketContract

Use this entity to explore and query all the MarketContracts that have been deployed.

Here are some nice fragments you can use in your query:

fragment MarketContractData on MarketContract {
  id
  name
  priceCap
  priceFloor
  isSettled
  settlementPrice
  lastPrice
  expirationTimestamp
  settlementTimeStamp
  oracleUrl
}

fragment ContractMeta on MarketContract {
  name
  priceFloor
  priceCap
  priceDecimalPlaces
  qtyMultiplier
  expirationTimestamp
}

fragment ContractFees on MarketContract {
  collateralTokenFeePerUnit
  mktTokenFeePerUnit
}

fragment ContractCollateral on MarketContract {
  collateralTokenAddress
  collateralPerUnit
}

fragment OracleData on MarketContract {
  oracleUrl
  oracleStatistic
}

fragment MarketPositionTokens on MarketContract {
  longPositionToken {
    id name symbol decimals marketSide
  }
  shortPositionToken {
    id name symbol decimals marketSide
  }
}

PositionToken

Use this entity to explore the different position tokens.

Here are some fragments you can use:

fragment PositionTokenData on PositionToken {
      id
      name
      symbol
      decimals
      marketSide
    }

PositionTokenOwner

Use this entity to fetch position token owners and their balances.

PositionTokenMintedEvent

Use this entity to fetch history of minting of a particular token or watch for minting events through subscriptions.

PositionTokenRedeemedEvent

Use this entity to fetch history of redemptions of a particular token or watch for redeeming events through subscriptions.

Example Queries

Here are some examples of some queries you can try out to see results or better still you could visit the demo website to see some of them in action.

export const PositionTokensQuery = gql`
  query {
    positionTokens(first: 10) {
      ...PositionTokenData
    }
  }
`;

export const AllMarketContractsQuery = gql`
  query {
    marketContracts(first: 10) {
      ...MarketContractData
    }
  }
`;

export const AllMarketContractsWithPositionTokensQuery = gql`
  query {
    marketContracts(first: 10) {
      ...MarketContractData
      shortPositionToken {
        ...PositionTokenData
      }
      longPositionToken {
        ...PositionTokenData
      }
    }
  }
`;

export const PositionTokenOwnerWithAddress = gql`
  query($ownerAddress: String) {
    positionTokenOwners(where: { owner: $ownerAddress }) {
      id
      owner
      token {
        ...PositionTokenData
      }
      balance
    }
  }
`;

export const AllMarketContractsWithPositionTokensExpiringWithinQuery = gql`
  query($gt: BigInt, $lt: BigInt) {
    marketContracts(
      first: 10
      where: { expirationTimestamp_gt: $gt, expirationTimestamp_lt: $lt }
    ) {
      ...MarketContractData
      shortPositionToken {
        ...PositionTokenData
      }
      longPositionToken {
