Introduction

In the world of cryptocurrencies, ERC20 tokens have gained significant popularity. These tokens are built on the Ethereum blockchain and serve various purposes, from utility tokens for decentralized applications to security tokens representing fractional ownership of assets. As an investor or trader, it is crucial to have access to real-time information about the price of ERC20 tokens. In this article, we will explore how you can obtain the price of an ERC20 token using Chainbase, a reliable API provider.

Understanding ERC20 Tokens

Before diving into the process of obtaining token prices, let’s briefly understand what ERC20 tokens are. ERC20 stands for Ethereum Request for Comments 20, which is a standard interface for tokens on the Ethereum blockchain. This standard ensures compatibility between different tokens, allowing them to be easily exchanged and interacted with on the Ethereum network.

ERC20 tokens have become the foundation for numerous blockchain projects and ICOs (Initial Coin Offerings). They provide a flexible and interoperable framework for creating fungible tokens, enabling developers to build decentralized applications and smart contracts.

The Importance of Tracking ERC20 Token Prices

The cryptocurrency market is known for its volatility, and ERC20 tokens are no exception. The prices of these tokens can fluctuate rapidly, presenting both opportunities and risks for investors and traders. To make informed decisions about buying, selling, or holding ERC20 tokens, it is essential to have access to accurate and up-to-date price information.

Tracking token prices allows investors to analyze historical trends, identify patterns, and assess market sentiment. It helps them determine the best entry and exit points, set realistic price targets, and manage their risk effectively. Additionally, knowing the price of an ERC20 token enables investors to calculate their portfolio value accurately.

Tools You Need to Work with Chainbase

To retrieve ERC20 token prices from Chainbase, you will need the following tools:

  1. A free account at Chainbase with an API key.
  2. An Integrated Development Environment (IDE) such as Visual Studio Code (VS Code).
  3. The ERC20 token’s address for which you want to obtain the price.

Setting up these tools will allow you to make API calls to Chainbase and fetch the desired token price data.

Step 1: Set up a Free Account at Chainbase

To leverage Chainbase’s functionalities, you need to create a free account. Follow these steps to set up your account:

  1. Visit the Chainbase website and click on the “get started” button.
  2. Fill in the required information, including your name, email address, and password.
  3. After creating an account, log in to Chainbase using your credentials.
  4. Once logged in, you will be redirected to the dashboard, where you can access various features and APIs.

Creating a free account at Chainbase gives you access to their API services and data cloud, enabling you to retrieve ERC20 token prices efficiently.

Step 2: Write Script Using Chainbase API

To retrieve the price of an ERC20 token from Chainbase, you can use either the fetch method or the axios library in JavaScript. Here’s an example script using both approaches:

Using fetch in JavaScript:


network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0xdAC17F958D2ee523a2206206994597C13D831ec7'; // Take USDT as an example.

fetch(`https://api.chainbase.online/v1/token/price?chain_id=${network_id}&contract_address=${token_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));


Using axios in JavaScript:

You need to install axios using npm install axios --save in the terminal first.


network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0xdAC17F958D2ee523a2206206994597C13D831ec7'; // Take USDT as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/token/price?chain_id=${network_id}&contract_address=${token_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));


Choose the method that suits your development environment and coding preferences. Ensure you replace the parameters with your network ID, token address, and Chainbase API key.

Step 3: Print the Token Price

After setting up your script, you can now execute it to retrieve the price of the ERC20 token.

Run command node .js in the terminal. In this case, the return data looks as follows.

Note that updated_at indicates the GMT time when you query the data, which may vary accordingly.

{
  price: 1.001497299920505,
  symbol: 'usd',
  source: 'coinmarketcap',
  updated_at: '2023-03-21T19:37:49.249213Z'
}

Replace `` with the name of your JavaScript file. Upon successful execution, you will receive the token price data, including the price value, symbol, source, and the timestamp of the latest update.

The data will be in JSON format, and you can further process it according to your requirements.
