Cryptocurrencies have revolutionized the financial landscape, offering new opportunities for investors and traders. Among the various types of cryptocurrencies, ERC20 tokens hold a prominent position. Built on the Ethereum blockchain, ERC20 tokens serve diverse purposes, ranging from utility tokens for decentralized applications to security tokens for fractional ownership of assets. If you are interested in investing, trading, or using ERC20 tokens, obtaining their historical price data is essential for making informed decisions.
1. Introduction to ERC20 tokens and their significance in the cryptocurrency market
Cryptocurrencies have gained widespread popularity, and ERC20 tokens have emerged as a prominent category within the market. ERC20 refers to the standard protocol for creating tokens on the Ethereum blockchain. These tokens adhere to a specific set of rules, enabling interoperability between different applications and platforms. Due to their compatibility and wide adoption, ERC20 tokens have become the backbone of numerous decentralized finance (DeFi) projects, initial coin offerings (ICOs), and tokenized assets.
2. The importance of historical ERC20 token price information
Understanding the historical price movements of ERC20 tokens is crucial for investors and traders. It provides valuable insights into token performance, trends, and market sentiment. Historical price data allows users to analyze patterns, identify potential buying or selling opportunities, and assess the overall market conditions. Whether you are a long-term investor or a short-term trader, having access to reliable historical ERC20 token price information is indispensable for making well-informed decisions.
3. Overview of Chainbase and the tools required to work with it
To access historical ERC20 token price data, we will utilize Chainbase, a platform offering comprehensive APIs and data cloud services. Before we dive into the process, there are a few tools you need to set up:
- Free account registration on Chainbase: Visit Chainbase's website and create a free account. This will grant you access to various APIs and data cloud services.
- IDE selection: Choose an integrated development environment (IDE) that suits your preferences. We recommend using Visual Studio Code (VS Code) as an example, but you can use any IDE that supports JavaScript.
- Token address as input: You will need the specific ERC20 token address for which you want to retrieve historical price data. This address uniquely identifies the token on the Ethereum blockchain.
4. Step-by-step guide to getting historical ERC20 token price using Chainbase API
Follow these steps to obtain the historical price of an ERC20 token using Chainbase API:
Step 1: Set up a free account at Chainbase
To leverage Chainbase's capabilities effectively, create a free account on their platform. Once you log in, visit the dashboard to familiarize yourself with the interface. Create a new project in the console and obtain an API key for authentication purposes.
Step 2: Write a script using Chainbase API
Depending on your preferred JavaScript library, you can use either fetch or axios to make API calls to Chainbase. Here's an example script using fetch:
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984'; // Take Uniswap as an example.
start_time = '1675209600'; // 2023-02-01 00:00:00 GMT in the format of epoch time.
end_time = '1677628800'; // 2023-03-01 00:00:00 GMT in the format of epoch time.
fetch(`https://api.chainbase.online/v1/token/price/history?chain_id=${network_id}&contract_address=${token_addr}&from_timestamp=${start_time}&end_timestamp=${end_time}`, {
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));
Alternatively, you can use axios as follows（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 = '0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984'; // Take Uniswap as an example.
start_time = '1675209600'; // 2023-02-01 00:00:00 GMT in the format of epoch time.
end_time = '1677628800'; // 2023-03-01 00:00:00 GMT in the format of epoch time.
const axios = require('axios');
const options = {
url: `https://api.chainbase.online/v1/token/price/history?chain_id=${network_id}&contract_address=${token_addr}&from_timestamp=${start_time}&end_timestamp=${end_time}`,
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));
5. Print historical ERC20 token price
The Chainbase API method getTokenPriceHistory takes the chain id, the contract address of a specific ERC20 token, start time, and end time as parameters. It then returns the historical price of that token during the provided time period. Run the script in your chosen IDE or execute it via the terminal. The response will contain an array of objects, with each object representing a specific price data point.
To get data printed, run command node <filename>.js in the terminal. In this case, the return data looks as follows
{
price: 6.6237146793,
symbol: 'usd',
source: 'coinmarketcap',
updated_at: '2023-02-01T23:59:59.999Z'
},
{
price: 7.1550444184,
symbol: 'usd',
source: 'coinmarketcap',
updated_at: '2023-02-02T23:59:59.999Z'
},
{
price: 7.1167093251499995,
symbol: 'usd',
source: 'coinmarketcap',
updated_at: '2023-02-03T23:59:59.999Z'
},
{
price: 7.1834694101,
symbol: 'usd',
source: 'coinmarketcap',
updated_at: '2023-02-04T23:59:59.999Z'
},
{

source: 'coinmarketcap',
updated_at: '2023-02-05T23:59:59.999Z'
},
