# eth\_getBalance - BSC

Example code for the eth\_getBalance JSON RPC method. Сomplete 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 BNB Smart Chain. The balance is returned in wei (the smallest unit of BNB, where 1 BNB = 10^18 wei). This method is essential for wallet applications, balance verification, and transaction preparation.

{% hint style="info" %}
Balances are returned in wei (1 BNB = 10^18 wei). Convert from hex wei to decimal and then to BNB by dividing by 1e18.
{% endhint %}

## Parameters

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