# Network stats

> Stream MultiversX TPS, block, mempool, shard, and health snapshots from the Relayer stats WebSocket.

Connect to `/ws/stats` to receive read-only MultiversX network snapshots without sending a subscribe message.

## Endpoint

```text theme={"system"}
wss://relayer.xoxno.com/ws/stats
```

Use `/ws` for topic subscriptions and `/ws/stats` for push-only network snapshots.

## Pushed Event

```json theme={"system"}
{
  "type": "networkStats",
  "data": {
    "network": {
      "notarizedTps": 18.5,
      "currentAps": 42
    },
    "mempool": {
      "estimatedQueue": 120,
      "pressure": 0.18
    },
    "shards": {
      "0": {
        "latestNonce": 123456,
        "blockTimeMsP50": 6000
      }
    }
  }
}
```
