# eth\_getBalance - SEI

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

Returns the balance of the account at the specified address on the Sei network. The balance is returned in wei (the smallest unit of SEI, where 1 SEI = 10^18 wei).

## Parameters

| Parameter | Type   | Description                                                                  |
| --------- | ------ | ---------------------------------------------------------------------------- |
| address   | string | The address to check for balance                                             |
| block     | string | Block number in hex, or 'latest', 'earliest', 'pending', 'safe', 'finalized' |
