How to Retrieve the Balance of a BEP-20 Token on the Binance Smart Chain Network?


The world of cryptocurrencies is constantly evolving, with new tokens and networks being introduced regularly. One such network that has gained significant popularity is the Binance Smart Chain (BSC) network. BSC is a blockchain platform that enables the creation and execution of smart contracts and decentralized applications (dApps). Within the BSC network, BEP-20 tokens play a crucial role in facilitating transactions and interactions. In this guide, we will delve into the details of retrieving the balance of a BEP-20 token on the Binance Smart Chain network, providing you with a comprehensive understanding of the process.

BEP-20 is a token standard on the Binance Smart Chain network, similar to the popular ERC-20 standard on the Ethereum network. This standard defines a set of rules and functions that all BEP-20 tokens must adhere to, ensuring compatibility and interoperability between tokens and dApps on the BSC network.

The BEP-20 standard offers several advantages. Firstly, it allows for seamless integration of BEP-20 tokens into existing decentralized exchanges (DEXs), wallets, and other applications built on the BSC network. This compatibility enhances liquidity and accessibility for BEP-20 token holders. Additionally, the standard provides a uniform interface for interacting with BEP-20 tokens, making it easier for developers to build decentralized applications that can handle multiple tokens simultaneously.

How to Retrieve the Balance of a BEP-20 Token on the Binance Smart Chain Network

The process of retrieving the balance of a BEP-20 token on the Binance Smart Chain network involves a few key steps.

  1. Exploring the BEP-20 Contract Address

The first step in retrieving the balance of a BEP-20 token is to identify the contract address of the token. The contract address is a unique identifier that represents the smart contract governing the token’s behavior and functionality. You can typically find the contract address on the BSCScan website or through the token’s official documentation.

Once you have the contract address, you can use it to interact with the token’s smart contract on the BSC network. The contract address serves as a reference point for retrieving token balances, executing transactions, and performing other operations related to the token.

  1. Accessing the BSC RPC node

To retrieve the balance of a BEP-20 token on the Binance Smart Chain network, you can use the BSC method. The BSC method involves connecting to the BSC network using an RPC (Remote Procedure Call) node. An RPC node acts as an interface between your application and the BSC network, allowing you to interact with smart contracts and retrieve token balances.

NOWNodes is a RPC node provider that offers access to various full nodes, including Binance Smart Chain and BNB Chain. It provides a platform where developers can easily access full nodes for multiple blockchain networks through RPC endpoints. This enables developers to interact with blockchain networks without having to set up and maintain their own nodes, which can be both time-consuming and costly.

To retrieve a token balance using the BSC method, you need to send a specific API call to the RPC node, providing the contract address and the wallet address associated with the balance you want to retrieve. The RPC node will process the request and return the token balance associated with the provided wallet address.

Here we will interact with the BSC RPC node via NOWNodes nodes as a service: 

1. Sign Up and API Key Generation: First, you’ll need to create a profile on the NOWNodes website ( Choose a tariff plan and blockchains you want to access. Notice that the START plan is free and allows you to pick up to 5 blockchains (including BSC mainnet endpoints) through one API key.

2. After registration, you have to generate an API key. This key is required to access their BSC RPC nodes. Always keep your API key secure and never expose it in client-side code to ensure your usage remains secure and within the platform’s guidelines.

3. Explore BSC Endpoint Information: NOWNodes will provide you with the BSC RPC endpoint for accessing the BSC mainnet network. NOWNodes offers documentation and support that can guide you through the functionalities and API calls you can make to the BSC RPC node.

The BSC RPC endpoint looks like ``. You’ll append your API key to this BSC RPC URL like so: ``, or insert it into the request header. You can test the connection directly from your web browser by pasting the BSC endpoint with the API key in Postman. 

Once you have the API key and the BSC RPC endpoint, you can plug these into your code to access BSC data. Whether you are using the Web3.js library, Ethers.js library, or direct HTTP calls, you’ll specify this BSC RPC endpoint for connection. 

  1. Retrieving the BEP-20 balance 
  • 1. Setup:
    • Make sure you have Node.js and npm installed.
    • Install the web3 library:

npm install web3

  • 2. Get the ABI (Application Binary Interface) of the BEP-20 Token:
    • Either obtain the ABI from the token’s official source, or
    • Go to BscScan, find your token, click on the Contract tab, and then on the ABI button to copy the ABI.
  • 3. Use Web3 to Interact with the Contract:

Here’s a simple Node.js script that you can use to retrieve the balance:

const Web3 = require('web3') 
const web3 = new Web3(new Web3.providers.HttpProvider("")) 
const ownerAddress = 'YOUR_ADDRESS_HERE' 
const tokenContractAddress = 'TOKEN_CONTRACT_ADDRESS_HERE' 
const tokenABI = [ ... ] 

const tokenContract = new web3.eth.Contract(tokenABI, tokenContractAddress) 
tokenContract.methods.balanceOf(ownerAddress).call((err, balance) => { if (err) { console.error('Error:', err); return; } 
const readableBalance = web3.utils.fromWei(balance, 'ether'); console.log(`Balance of address ${ownerAddress}:`, readableBalance); });

Replace 'YOUR_ADDRESS_HERE' with the address you want to check, and 'TOKEN_CONTRACT_ADDRESS_HERE' with the BEP-20 token contract address.

Run the script:

node script_name.js

This will print the balance of the specified address for the given BEP-20 token.

Remember! Binance Smart Chain is EVM-compatible, meaning it functions very similarly to Ethereum. Therefore, tools and libraries built for Ethereum, like web3.js, can be used with BSC by simply changing the network RPC.

Note: Always exercise caution when interacting with smart contracts, especially if executing any state-changing functions (like transfers).

Securing Your Private Key for Balance Retrieval on the Binance Smart Chain

When retrieving the balance of a BEP-20 token on the Binance Smart Chain network, it’s crucial to ensure the security of your private key. Your private key is the cryptographic key that allows you to access and control your wallet, including the ability to retrieve token balances. It’s essential to keep your private key secure and only share it with trusted applications or services.

To enhance the security of your private key, consider using hardware wallets or secure software wallets that offer robust encryption and multi-factor authentication. Additionally, be cautious of phishing attempts and ensure you are interacting with legitimate applications or services when providing your private key for balance retrieval.

Ensuring the Accuracy of Balance Retrieval through BSC Balance Check

To ensure the accuracy of balance retrieval on the Binance Smart Chain network, you can perform a BSC balance check. A BSC balance check involves cross-referencing the retrieved token balance with multiple reputable sources, such as BSCScan or other blockchain explorers. By comparing the retrieved balance with the information provided by these sources, you can verify the accuracy of the balance and identify any discrepancies or inconsistencies.

Performing a BSC balance check adds an extra layer of confidence and ensures that you have the correct information regarding your token balance. It helps prevent potential errors or misunderstandings that may arise from relying solely on a single data source.


Retrieving the balance of a BEP-20 token on the Binance Smart Chain network is a straightforward process that involves understanding the BEP-20 standard, identifying the token’s contract address, utilizing the BSC method for balance retrieval, securing your private key, performing a BSC balance check, and utilizing node providers for reliable balance retrieval. By following these steps and best practices, you can confidently access and manage your BEP-20 token balances on the Binance Smart Chain network.

Remember to always prioritize the security of your private key and verify the accuracy of retrieved balances through reputable sources. With the right knowledge and tools at your disposal, you can navigate the Binance Smart Chain network with ease and efficiency.
