# txpool\_content - BSC

This method returns all pending and queued transactions currently held in the transaction pool on the BNB Smart Chain, grouped first by sender address and then by nonce.

{% hint style="info" %}
The BSC mempool routinely holds thousands of transactions across hundreds of senders, so a full `txpool_content` response can be several megabytes. Use txpool\_status for counts only, [txpool\_inspect](/api-reference/bnb-smart-chain-bsc/txpool_inspect-bsc.md) for a compact text summary, or [txpool\_contentFrom](/api-reference/bnb-smart-chain-bsc/txpool_contentfrom-bsc.md) to scope the result to a single sender.

## Use Cases

* Inspect the full mempool before submitting a competing transaction
* Detect stuck transactions and nonce gaps for a set of accounts
* Build MEV and arbitrage tooling that reacts to unconfirmed transactions
* Debug why a submitted transaction is not being mined

## Error Handling

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