Ethereum: How do you get the balance of an address in your wallet using the rpc interface?

How ​​to Get Ethereum Wallet Balance Using RPC Interface

The Ethereum development team provides a RESTful API called RPC (Remote Procedure Call) that allows developers to programmatically interact with the Ethereum network. One of the most commonly used APIs is the eth_accounts endpoint, which returns a list of addresses that have been added to the Ethereum network.

In this article, we will explore how to use the RPC interface to get the balance of an address in your wallet. Ethereum uses the eth_accounts endpoint.

Why Use the RPC Interface?

The RPC interface is primarily used for testing and development purposes. However, it can also be used for integration with third-party applications that require access to the user’s Ethereum account information.

To get the balance of an address in your wallet using the RPC interface, you will need to:

• Get a List of Accounts – Use the eth_accounts endpoint to retrieve a list of addresses that have been added to the network.

• Select the desired address: Once you have a list of addresses, select the one you want to get information about.

RPC Interface Endpoint

The eth_accounts endpoint returns a JSON response with the following structure:

`json

Where[address1],[address2], etc. are Ethereum addresses.

Use Case Example
Let's say you have an Ethereum wallet with three addresses:
0x[Address1]: This is the primary wallet address.
0x[Address2]: This is a secondary wallet address used for testing purposes.
0x[Address3]: This is a test wallet address.
To get the balance of Address 2 (the second address of the main wallet), you can use the following RPC command:
blow
curl -X GET \

Replace [Address2]with your actual Ethereum address.

The response from theeth_accountsendpoint will be a JSON object containing information about all the accounts in the list. To specifically get the balance of Address 2, you can use the following API call:

blow

“

Note: This is just an example and may not work in all environments. The “eth_accounts” endpoint may require authentication and the API response may vary depending on your Ethereum node or wallet provider.

In conclusion, use the RPC interface to get the balance of an address in your wallet. Ethereum provides a convenient way to retrieve information about specific addresses without having to interact directly with the wallet programmatically.
