# txpool\_inspect - BSC

This method returns a compact, human-readable summary of the pending and queued transactions in the transaction pool on the BNB Smart Chain. It has the same sender-and-nonce nesting as [txpool\_content](/api-reference/bnb-smart-chain-bsc/txpool_content-bsc.md), but each transaction is reduced to a single summary string instead of a full object, which makes the response far smaller.

## Parameters

* None

## Response Parameters

| Parameter | Type   | Description                                                                 |
| --------- | ------ | --------------------------------------------------------------------------- |
| pending   | object | Transactions eligible for inclusion, keyed by sender address, then by nonce |
| queued    | object | Transactions not yet processable, with the same nesting                     |

Each leaf value is a string in the form `<to>: <value> wei + <gas> gas × <gasPrice> wei`, where all numbers are decimal rather than hex-encoded.

| Segment    | Description                  |
| ---------- | ---------------------------- |
| `to`       | Recipient address            |
| `value`    | BNB transferred, in wei      |
| `gas`      | Gas limit of the transaction |
| `gasPrice` | Gas price offered, in wei    |

## Use Cases

* Survey mempool contents without transferring megabytes of transaction data
* Spot senders offering unusually high gas prices
* Identify nonce gaps that leave transactions stuck in the queued set
* Feed lightweight mempool dashboards and alerting

## Error Handling

| Error Code | Description          |
| ---------- | -------------------- |
| -32601     | Method not supported |
| -32603     | Internal error       |
