===============
Cryptocurrency enthusiasts often seek ways to efficiently manage their token holdings and check their balances. With the Chainbase API’s getAccountTokens
functionality, you can automate the process of retrieving ERC20 token balances owned by a specific wallet address. This not only saves time but also provides a convenient way to stay updated on your token investments.
- Overview of Tools Needed
===========================
Before diving into the implementation, it’s essential to ensure you have the necessary tools in place. Here’s what you’ll need:
1. Free Account at Chainbase with an API Key
To leverage the power of Chainbase, you should register for a free account. This account grants you access to various APIs and data cloud services provided by Chainbase.
2. IDE Recommendation: VS Code
While the examples provided in this article are in JavaScript, you can use any IDE of your choice. However, we recommend using Visual Studio Code (VS Code) due to its extensive features, code editing capabilities, and popularity within the developer community.
3. Wallet Address as Input
To retrieve ERC20 token balances, you’ll need a known wallet address as your input. This could be your own address or any other address you wish to inspect.
- Set up a Free Account at Chainbase
=====================================
To begin, let’s set up your free account at Chainbase and obtain an API key. Follow these steps:
-
Register for a free account at Chainbase by visiting our website.
-
Once you’ve registered and logged in, navigate to the dashboard to get an overview of the available features.
-
Create a new project in the Chainbase console. This project will be associated with your account and allow you to manage your API key and other settings.
-
After creating the project, you’ll be provided with an API key. This key serves as a unique identifier for your account when making API requests.
-
Write a Script Using Chainbase API
=====================================
Now that you have your Chainbase account and API key, you can proceed to write a script that utilizes the Chainbase API. Here are examples using both the Fetch and Axios libraries in JavaScript:
Using Fetch in JavaScript:
<span style="color:#323232;">network_id = '1'; // See to get the id of different chains.
</span><span style="color:#323232;">wallet_addr = '0xd8dA6
</span><span style="color:#323232;">
</span><span style="color:#323232;">BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.
</span><span style="color:#323232;">
</span><span style="color:#323232;">fetch(`https://api.chainbase.online/v1/account/tokens?chain_id=${network_id}&address=${wallet_addr}&limit=5&page=1`, {
</span><span style="color:#323232;"> method: 'GET',
</span><span style="color:#323232;"> headers: {
</span><span style="color:#323232;"> 'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
</span><span style="color:#323232;"> 'accept': 'application/json'
</span><span style="color:#323232;"> }
</span><span style="color:#323232;">}).then(response => response.json())
</span><span style="color:#323232;"> .then(data => console.log(data.data))
</span><span style="color:#323232;"> .catch(error => console.error(error));
</span><span style="color:#323232;">
</span>
Using Axios in JavaScript:
You need to install axios
using npm install axios --save
in the terminal first.
<span style="color:#323232;">network_id = '1'; // See to get the id of different chains.
</span><span style="color:#323232;">wallet_addr = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.
</span><span style="color:#323232;">
</span><span style="color:#323232;">const axios = require('axios');
</span><span style="color:#323232;">const options = {
</span><span style="color:#323232;"> url: `https://api.chainbase.online/v1/account/tokens?chain_id=${network_id}&address=${wallet_addr}&limit=5&page=1`,
</span><span style="color:#323232;"> method: 'GET',
</span><span style="color:#323232;"> headers: {
</span><span style="color:#323232;"> 'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
</span><span style="color:#323232;"> 'accept': 'application/json'
</span><span style="color:#323232;"> }
</span><span style="color:#323232;">};
</span><span style="color:#323232;">axios(options)
</span><span style="color:#323232;"> .then(response => console.log(response.data.data))
</span><span style="color:#323232;"> .catch(error => console.log(error));
</span><span style="color:#323232;">
</span>
Make sure to replace CHAINBASE_API_KEY
with your actual API key obtained from your Chainbase account.
- Print the ERC20 Token Balances
=================================
The Chainbase API’s getAccountTokens
endpoint takes the chain ID and wallet address as parameters and returns the ERC20 token balances associated with the provided address. You can also specify a particular token by supplying its contract address.
To print the ERC20 token balances, follow these steps:
- Save your script file with a
.js
suffix. - Open your terminal.
- Navigate to the directory where you saved the script file.
- Execute the command
node .js
, replacing `` with the actual name of your script file.
Upon running the script, you’ll receive a response similar to the following, displaying the balances of ERC20 tokens owned by the specified address:
<span style="color:#323232;">{
</span><span style="color:#323232;"> "balance": "0x2386f26fc10000",
