# eth\_getTransactionCount - BSC

This method returns the number of transactions sent from an address (nonce) on the BNB Smart Chain. This is essential for creating new transactions, as each transaction requires the correct nonce.

## Parameters

| Parameter   | Type   | Required | Description                         |
| ----------- | ------ | -------- | ----------------------------------- |
| address     | string | Yes      | Address to get nonce for            |
| blockNumber | string | Yes      | Block number or "latest", "pending" |
