# txpool_contentFrom | Arc

> Arc API method that returns the pending and queued transactions in the node's pool for a single sender address. Use it on Arc via Chainstack.

Arc API method that returns the transactions in the node's pool for one sender address. It is [txpool\_content](/reference/arc-txpool-content) narrowed to a single account, so the response stays small on a busy node.

## Parameters

* `address` — the sender address to filter the pool by.

## Response

* `pending` — the sender's transactions that are ready for inclusion, keyed by nonce.
* `queued` — the sender's transactions held back by a nonce gap, keyed by nonce.

<Note>
  Arc produces a block roughly every 0.5 seconds, so a healthy sender's transactions usually clear before you can observe them. An empty result means nothing was pending for that address at that moment.
</Note>

## `txpool_contentFrom` code examples

<CodeGroup>
  ```javascript ethers.js theme={"system"}
  const { JsonRpcProvider } = require("ethers");

  const provider = new JsonRpcProvider("CHAINSTACK_NODE_URL");

  async function call() {
    const result = await provider.send("txpool_contentFrom", ["0x5d20879655df3c1e04ab111af0009ad650e762f0"]);
    console.log(result);
  }

  call();
  ```

  ```python web3.py theme={"system"}
  from web3 import Web3

  node_url = "CHAINSTACK_NODE_URL"
  web3 = Web3(Web3.HTTPProvider(node_url))

  result = web3.provider.make_request("txpool_contentFrom", ["0x5d20879655df3c1e04ab111af0009ad650e762f0"])
  print(result)
  ```

  ```shell cURL theme={"system"}
  curl -X POST "CHAINSTACK_NODE_URL" \
    -H "Content-Type: application/json" \
    --data '{
      "jsonrpc": "2.0",
      "method": "txpool_contentFrom",
      "params": ["0x5d20879655df3c1e04ab111af0009ad650e762f0"],
      "id": 1
    }'
  ```
</CodeGroup>

## Use case

When a user reports that a transaction is not landing, this answers the question directly for their address alone. If the transaction sits in `queued` rather than `pending`, the sender has a nonce gap and every later transaction stays parked until the missing nonce is filled.
