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

Ethereum Address Balances: A Complete Guide

As a digital asset owner, managing multiple Ethereum addresses can be a daunting task. With thousands of unique addresses on the Ethereum network, keeping track of balances can quickly become overwhelming. In this article, we’ll explore the best ways to get your hands on Ethereum address balances and provide insight into 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 essential because they determine ownership and control of your assets.

Why Get Your Ethereum Address Balance?

Managing multiple addresses can be stressful due to:

• High Fees: Transaction fees on the Ethereum network can skyrocket, making it difficult to maintain large balances.

• Limited APIs: Most standard APIs, such as those provided by CoinDesk or Etherscan, have limitations in terms of request frequency and size.

• Security Risks

  : Unverified balances can expose your assets to potential theft or tampering.

Best Way to Get Your Ethereum Address Balance

To efficiently 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 (Node.js) code example:

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 retrieve your Ethereum address balance using 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 that offer premium services

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

• Increased request limits

  

  : Higher limits allow you to make more requests without hitting the API rate limits.

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

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