Bybit Futures API Integration Using ccxt Library with Error Handling

• The columns array specifies how data fields (e.g., username, points) map to table columns.

• language.emptyTable: Custom message displayed when no data is available.

• $response->successful(): Returns true if the response has a status code of 200-299.
• $response->failed(): Returns true if the request failed (status code of 400 or greater).

Other useful methods include:

const axios = require('axios');

// Replace with your Etherscan API key
const apiKey = 'YOUR_ETHERSCAN_API_KEY';

// Replace with the wallet address you want to query
const address = '0xYourEthereumAddress';

// Replace with the ERC-20 token contract address
const contractAddress = '0xTokenContractAddress';

// Etherscan API URL to fetch ERC-20 token transactions
const url = `https://api.etherscan.io/api?module=account&action=tokentx&contractaddress=${contractAddress}&address=${address}&startblock=0&endblock=99999999&sort=asc&apikey=${apiKey}`;

async function getTokenTransactions() {
    try {
        // Make the API request to Etherscan
        const response = await axios.get(url);
        const transactions = response.data.result;

        // Log the token transactions
        transactions.forEach(tx => {
            console.log(`
                From: ${tx.from}
                To: ${tx.to}
                Value: ${ethers.utils.formatUnits(tx.value, 18)} Tokens
                Transaction Hash: ${tx.hash}
            `);
        });
    } catch (error) {
        console.error('Error fetching token transactions:', error);
    }
}

// Call the function to get the token transactions
getTokenTransactions();

• API Key: Replace 'YOUR_ETHERSCAN_API_KEY' with the API key you generated from Etherscan.
• Wallet Address: Replace '0xYourEthereumAddress' with the wallet address you want to query for token transactions.
• Token Contract Address: Replace '0xTokenContractAddress' with the contract address of the ERC-20 token you want to track.

In this tutorial, we will compare Etherscan and Infura, two popular services for interacting with the Ethereum blockchain. Both provide APIs, but they serve different purposes and are suited for different types of applications. By understanding the strengths of each, you can choose the right one based on your specific use case, whether it involves querying blockchain data or interacting with the Ethereum network in real-time.

• Basic understanding of Ethereum and blockchain concepts.
• Familiarity with APIs and programming in Node.js or any other language.

   https://api.etherscan.io/api?module=account&action=txlist&address=0xYourEthereumAddress&startblock=0&endblock=99999999&sort=asc&apikey=YOUR_API_KEY

   https://api.etherscan.io/api?module=account&action=tokentx&address=0xYourEthereumAddress&startblock=0&endblock=99999999&sort=asc&apikey=YOUR_API_KEY

To follow along, you’ll need the following:

• Node.js installed on your machine.
• Basic understanding of JavaScript.
• An Ethereum wallet (with private key or mnemonic phrase).
• (Optional) An Infura account to access the Ethereum network.

For example, in token burn events, project developers often send tokens to this address to signal to the community that those tokens are now out of circulation. This is usually followed by a public announcement, detailing the number of tokens burned and the reasons behind the burn.

Token burns are typically done to increase scarcity, and scarcity can lead to a higher token value if demand remains the same or increases. The basic principle of supply and demand comes into play: when the supply of an asset is reduced, it becomes more valuable (assuming demand holds steady).

Before the Fetch API, the traditional way to make AJAX requests was using XMLHttpRequest.

   function createLeak() {
       const hugeArray = new Array(1000000).fill('leak');
       return () => console.log(hugeArray.length);
   }

   const leakyFunction = createLeak();
   // hugeArray is never garbage collected because it's referenced in leakyFunction

• Detached DOM nodes are elements that have been removed from the DOM tree but are still referenced in JavaScript.

Axios is a powerful and flexible library for making HTTP requests in JavaScript. Whether you're fetching data, submitting forms, or handling complex API interactions, Axios simplifies the process with its clean and consistent API. By mastering the basics covered in this tutorial, you'll be well-equipped to use Axios in your own projects.

• Experiment with making requests to different APIs.
• Explore more advanced Axios features like interceptors and request cancellation.
• Consider using Axios in a framework like React or Vue.js for even more powerful applications.

Inline assembly allows for low-level operations and optimizations.

function multiply(uint a, uint b) public pure returns (uint) {
    uint result;
    assembly {
        result := mul(a, b)
    }
    return result;
}

In your Python script, initialize the Pybit HTTP client:

   api_key = os.getenv('BYBIT_API_KEY')
   api_secret = os.getenv('BYBIT_API_SECRET')

   session = HTTP(
       endpoint='https://api.bybit.com',
       api_key=api_key,
       api_secret=api_secret
