Ethereum: How to get balance from tens of thousands of addresses?

Ethereum Address Balance: The Ultimate Guide

As a digital asset owner, managing multiple Ethereum addresses can seem like a daunting task. With thousands of unique addresses on the Ethereum network, keeping track of balances can quickly become a pain. In this article, we’ll take a look at the best ways to get Ethereum address balances and provide information on APIs that offer premium services.

What is an Ethereum Address Balance?

An Ethereum address balance refers to the amount of Ether (ETH) or other available tokens stored in a specific Ethereum account. Understanding how address balances work is crucial, as they determine ownership and control over your assets.

Why Maintain Your Ethereum Address Balance?

Managing multiple addresses can be stressful for the following reasons:

• High fees: Ethereum transaction fees can skyrocket, making it difficult to maintain large balances.

• Limited API: Most standard APIs, such as those provided by CoinDesk or Etherscan, have limitations on the frequency and size of requests.

• Security Risks: Unverified balances can expose your assets to potential theft or manipulation.

Best Way to Get Your Ethereum Address Balance

To effectively access your Ethereum address balance, consider the following methods:

1.
Etherscan API

Etherscan offers a free API that allows you to retrieve your Ethereum address balance in JSON format. You can use their API client library (for Node.js) or their HTTP request libraries (e.g. requests in Python).

Etherscan API Code Example (Node.js):

const etherscan = require('etherscan-api');
const accountAddress = '0x1234567890abcdef'; // Replace with your address
etherscan.getBalance(accountaddress, { from: null })
.then((balance) => console.log(balance))
.catch((error) => console.error(error));

2.
CoinDesk API

CoinDesk provides a free API that retrieves Ethereum address balances in JSON format.

CoinDesk API Code Example (Node.js):

const coinDesk = require('coindesk-api');
const accountAddress = '0x1234567890abcdef'; // Replace with your address
coinDesk.getBalance(accountaddress)
.then((balance) => console.log(balance))
.catch((error) => console.error(error));

3.
ethers.js

ethers.js is a popular Node.js library that provides a simple way to interact with Ethereum accounts.

Ethers.js Code Example:

const ethers = require('ethers');
const accountAddress = '0x1234567890abcdef'; // Replace with your address
ethers.getBalance(accountaddress)
.then((balance) => console.log(balance))
.catch((error) => console.error(error));

4.
Exchanges (e.g. Binance, Kraken)

You can also check the balance of your Ethereum address through exchanges. These platforms often provide APIs that allow you to access account balances.

Binance API Code Example (Node.js):

const binance = require('binance-api');
const accountAddress = '0x1234567890abcdef'; // Replace with your address
binance.getBalance(accountaddress)
.then((balance) => console.log(balance))
.catch((error) => console.error(error));

APIs offering premium services

To bypass the limitations of standard APIs, consider using premium services that offer:

• Higher request limits

  : Higher limits allow you to send more requests without exceeding the API’s bandwidth limits.

• Custom API keys: These types of services typically provide unique API keys for each account or user, reducing the risk of API key theft.

• Advanced analytics: Some APIs offer advanced analytics and insight into your account balances, helping you optimize your asset management.
