# Whitelist subgraph

The whitelist stores trusted data providers, their individual data feeds and the collateral tokens that have to be used in order to be eligible for the oracle services:

The whitelist subgraph can be accessed here: 

* Ropsten (deprecated): <https://thegraph.com/hosted-service/subgraph/divaprotocol/diva-whitelist-ropsten>
* Goerli: <https://thegraph.com/hosted-service/subgraph/divaprotocol/diva-whitelist-goerli>

## Data providers

Data providers can be and their offered data feeds can be queried as follows (here querying the first two data providers in the whitelist):

```
{
  dataProviders(first: 2) {
    id
    name
    publicTrigger
    dataFeeds {
      id
      referenceAsset
      referenceAssetUnified
      active
    }
  }
}
```

Sample output of above query:

```
{
  "data": {
    "dataProviders": [
      {
        "id": "0x9adefeb576dcf52f5220709c1b267d89d5208d78",
        "name": "Individual 1",
        "publicTrigger": false,
        "dataFeeds": [
          {
            "id": "0x9adefeb576dcf52f5220709c1b267d89d5208d78-0",
            "referenceAsset": "DIVA/USD",
            "referenceAssetUnified": "DIVA/USD",
            "active": true
          },
          {
            "id": "0x9adefeb576dcf52f5220709c1b267d89d5208d78-1",
            "referenceAsset": "BTC/USD",
            "referenceAssetUnified": "BTC/USD",
            "active": true
          }
        ]
      },
      {
        "id": "0xed6d661645a11c45f4b82274db677867a7d32675",
        "name": "Tellor",
        "publicTrigger": true,
        "dataFeeds": [
          {
            "id": "0xed6d661645a11c45f4b82274db677867a7d32675-0",
            "referenceAsset": "ETH/USD",
            "referenceAssetUnified": "ETH/USD",
            "active": true
          },
          {
            "id": "0xed6d661645a11c45f4b82274db677867a7d32675-1",
            "referenceAsset": "BTC/USD",
            "referenceAssetUnified": "BTC/USD",
            "active": true
          }
        ]
      }
    ]
  }
}
```

## Data feeds

The following query shows all data providers that can provide a given data feed (here ETH/USD):

```
{
  dataFeeds(where:{referenceAssetUnified:"ETH/USD", active:true}) {
    id
    referenceAsset
    referenceAssetUnified
    dataProvider {
      id
      name
      publicTrigger
    }
    active
  }
}

```

Sample output of above query:

```
{
  "data": {
    "dataFeeds": [
      {
        "id": "0xed6d661645a11c45f4b82274db677867a7d32675-0",
        "referenceAsset": "ETH/USD",
        "referenceAssetUnified": "ETH/USD",
        "dataProvider": {
          "id": "0xed6d661645a11c45f4b82274db677867a7d32675",
          "name": "Tellor",
          "publicTrigger": true
        },
        "active": true
      }
    ]
  }
}
```

## Collateral tokens

The following query returns all collateral tokens that are supported by whitelisted data providers:

```
{
  collateralTokens(first:2){
    id
    name
    symbol
    decimals
  }
}

```

Sample output of above query:

```
{
  "data": {
    "collateralTokens": [
      {
        "id": "0x384a78a65189c696a009681b20880cd9af01bc16",
        "name": "WAGMI20",
        "symbol": "WAGMI20",
        "decimals": 20
      },
      {
        "id": "0x867e53fede91d27101e062bf7002143ebaea3e30",
        "name": "WAGMI18",
        "symbol": "WAGMI18",
        "decimals": 18
      }
    ]
  }
}
```
