# eth\_getTransactionCount - Celo

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

This method returns the number of transactions sent from an address on the Celo network. This value is also known as the nonce and is essential for transaction signing and preventing replay attacks.

## Parameters

| ----------- | ------ | -------- | ------------------------------------------------------- |
| address     | string | Yes      | The address to get transaction count for                |
| blockNumber | string | Yes      | Block number in hex, or "latest", "earliest", "pending" |
