# eth\_getTransactionCount - Somnia

This method returns the number of transactions sent from an address (the nonce) on the Somnia network. This is critical for transaction construction, as each transaction must have the correct nonce to be valid. With Somnia's high throughput, nonce management is important for rapid transaction submission.

## Parameters

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