# eth\_getTransactionCount - Ethereum

Example code for the eth\_getTransactionCount JSON RPC method. Сomplete guide on how to use eth\_getTransactionCount JSON RPC in GetBlock Web3 documentation.

This method returns the number of transactions sent from an address, hex-encoded. This is the address's nonce — the counter used to order transactions from the same sender. Wallets read this before signing to set the correct nonce; nonce-management bugs are a common source of stuck or replaced transactions.

## Parameters

| Parameter        | Type   | Required | Description                                                                  |
| ---------------- | ------ | -------- | ---------------------------------------------------------------------------- |
| `address`        | string | Yes      | 20-byte address to query (hex-encoded with `0x` prefix)                      |
| `blockParameter` | string | Yes      | Block number in hex, or `latest`, `earliest`, `pending`, `finalized`, `safe` |

## Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0x462"
}
```

## Response Parameters

| Parameter | Type   | Description                                                                  |
| --------- | ------ | ---------------------------------------------------------------------------- |
| `jsonrpc` | string | JSON-RPC protocol version ("2.0")                                            |
| `id`      | string | Request identifier matching the request                                      |
| `result`  | string | Hex-encoded transaction count (nonce) for the address at the requested block |

## Use Cases

* **Nonce Management**: Set the `nonce` field when signing a transaction — typically use `pending` to include queued but unmined transactions
* **Account Activity Snapshots**: Show total sent-transaction count for an address in an explorer or wallet UI
* **Stuck-Transaction Recovery**: Diagnose whether a transaction is truly stuck by comparing on-chain nonce to expected nonce
* **Batch Transaction Sequencing**: Reliably enqueue N transactions with sequential nonces from a hot wallet

## Error Handling

| Error Code | Message        | Description                                                 |
| ---------- | -------------- | ----------------------------------------------------------- |
| -32602     | Invalid params | Address is malformed, or block parameter is invalid         |
| -32603     | Internal error | Node failed to look up account state at the requested block |
