# txpool\_status - Ethereum

This method returns the number of pending and queued transactions currently held in the node's transaction pool. It is the cheapest of the `txpool_*` methods: the response is two integers regardless of how busy the mempool is.

## Parameters

This method takes no parameters.

## Request

## Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": {
        "pending": "0x1739e",
        "queued": "0x36f3"
    }
}
```

## Response Parameters

| Parameter | Type   | Description                                                                   |
| --------- | ------ | ----------------------------------------------------------------------------- |
| `jsonrpc` | string | JSON-RPC protocol version ("2.0")                                             |
| `id`      | string | Request identifier matching the request                                       |
| `pending` | string | Hex-encoded count of transactions eligible for inclusion (`0x1739e` = 95,134) |
| `queued`  | string | Hex-encoded count of transactions not yet processable (`0x36f3` = 14,067)     |

## Use Cases

* **Congestion Monitoring**: Track mempool depth over time to gauge network load
* **Confirmation Estimates**: Combine pending depth with block gas limits to estimate wait times
* **Node Health Checks**: Confirm an endpoint is peered and receiving transactions
* **Cheap Polling**: Detect mempool changes before paying for a full [txpool\_content](/api-reference/ethereum-eth/txpool_content-ethereum.md) call

## Error Handling

| Error Code | Message          | Description                                         |
| ---------- | ---------------- | --------------------------------------------------- |
| -32601     | Method not found | The `txpool` module is not enabled on this endpoint |
| -32603     | Internal error   | Node failed to read the transaction pool            |
