# K2 Subgraph

Restaking cloud has created a subgraph for the K2 protocol:

```
https://thegraph.com/hosted-service/subgraph/restaking-cloud/k2-protocol
```

Data points will be added over time for the K2 subgraph. Highlights include:

* Natively delegated BLS public keys
* Node runner representatives for the BLS public keys
* Activity events
* Reward claims

`Holesky` support for K2 is comming soon.

## Querying all natively delegated BLS public keys

This is the query for establishing which Goerli validator, regardless of liquid staking protocol or solo staker, has natively delegated to K2 via [MEV Plus](../docs-middleware/mevPlusModule.md):

```graphql theme={null}
{
  blspublicKeys(first: 1000) {
    id
  }
}
```

### Example response:

```json theme={null}
{
  "data": {
    "blspublicKeys": [
      {
        "id": "0x82216ed82308bd4a2db9d4ba960b275e5ca50ac6924ed7199d7d7f1d31c4e2a4e2499a9bc52e4c4c0d07589887106469"
      }
    ]
  }
}
```

### Querying the validators natively delegated by a specific node runner

In order to query the natively delegated validators by the Ethereum wallet address of a node runner, the following query can be run (make sure to replace the node runner address with the correct address and also make sure the node runner address is `ALL` lower case):

```graphql theme={null}
{
  blspublicKeys(
    first: 1000
    where: { nodeRunner: "0x7d3e58a4aea62417807a5c0929d936372a0a42fe" }
  ) {
    id
  }
}
```

Example response:

```json theme={null}
{
  "data": {
    "blspublicKeys": [
      {
        "id": "0x800330fec42ea0a795f5f87751bca39ce22858ef2828a12452505a4a5563c5c31519261f7167de746eb12bf92ae875d3"
      }
    ]
  }
```

## Querying protocol activity events

The following can be used to see what activity is taking place in the underlying protocol (ordered from newest to oldest event):

```graphql theme={null}
{
  events(orderBy: blockNumber, orderDirection: desc, first: 1000) {
    keys
    values
  }
}
```
