How to Check ETH Balance on the Ethereum Blockchain

·

Introduction to ETH Balance Checking

To check your Ethereum (ETH) balance on the Ethereum blockchain, you'll need access to an Ethereum node or a reliable API service. This process is similar to checking BNB balances on Binance Smart Chain (BSC) but requires different endpoints.

Key Services for ETH Balance Queries

Here are two trusted providers offering free Ethereum node access:

  1. Infura – A widely used Ethereum API with free tier access.
  2. Alchemy – Provides robust Ethereum node infrastructure.

Step-by-Step Guide

Step 1: Choose a Service

Select either Infura or Alchemy and sign up for a free account to obtain your API endpoint.

Step 2: Use Web3 Libraries

With the endpoint, you can query balances using:

Example (Web3.js):

const Web3 = require('web3');
const web3 = new Web3('YOUR_INFURA_ENDPOINT');
const balance = await web3.eth.getBalance('0xYourWalletAddress');
console.log(balance);

Step 3: Parse the Result

The returned value is in wei (1 ETH = 10¹⁸ wei). Convert it to ETH using:

const etherBalance = web3.utils.fromWei(balance, 'ether');

FAQ Section

Q1: Can I check ETH balance without running a node?

Yes! Services like Infura/Alchemy act as intermediaries, so you don’t need local node setup.

Q2: Are these APIs free?

Both offer free tiers with rate limits, sufficient for personal/testing use.

Q3: How accurate is the balance returned?

The data reflects real-time blockchain state, ensuring accuracy.

Q4: What if my query fails?

Conclusion

Checking ETH balances requires:

  1. A node provider (Infura/Alchemy)
  2. A wallet address
  3. Simple code implementation

For developers, running a local node (e.g., Geth) offers full control but demands higher resource commitment.
