# eth\_getBalance - Somnia

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

This method returns the balance of the account at a given address on the Somnia network. The balance is returned in wei (the smallest unit of SOMI, where 1 SOMI = 10^18 wei). This method is essential for wallet applications, balance verification, and transaction preparation.

## Parameters

| Parameter | Type   | Required | Description                                             |
| --------- | ------ | -------- | ------------------------------------------------------- |
| address   | string | Yes      | The address to check balance (20 bytes, 0x-prefixed)    |
| block     | string | Yes      | Block number in hex, or "latest", "earliest", "pending" |
