However, fetching your token balance can sometimes lead to confusing errors—especially if you're new to smart contracts and JavaScript coding. Today, we're going to break down how to retrieve your USDT balance using simple steps, while also troubleshooting a common error you might encounter along the way. The Problem: Fetching Your USDT Balance When attempting to retrieve your USDT balance using the Ethereum blockchain, you might run into the following error: “Returned values aren't valid, did it run Out of Gas?” This error may arise due to several factors, such as: Incorrect ABI (Application Binary Interface) used for the USDT contract Querying a node that is not fully synced Requesting data from a nonexistent block number Let’s dive into how you can successfully retrieve your balance and resolve any underlying issues. The Solution: Fetching the USDT Balance Understand the Basic Structure of the Code Your initial code snippet includes crucial components but may be encountering problems due to a faulty ABI. Here’s a recap of the important parts of your code structure: [[See Video to Reveal this Text or Code Snippet]] Revise the ABI Adjust the ABI to ensure that it is correctly formatted for fetching the USDT balance. The revised ABI should include a stateMutability field which specifies the nature of the function call. Here’s a suggested code for your updated ABI: [[See Video to Reveal this Text or Code Snippet]] State Mutability: By setting the stateMutability to view, you indicate that this function will only read data from the blockchain without making any changes, which is essential for fetching balances. Implement the Function to Get Your Balance Next, ensure your function to retrieve the balance of USDT is set up correctly. Here's a modified version based on the original snippet you shared: [[See Video to Reveal this Text or Code Snippet]] Test the Changes Now that you have updated the ABI and ensured your function is correct, run your JavaScript code again in your development environment. You should now see your USDT balance printed to the console. Troubleshooting Further Issues If you still encounter problems after this adjustment: Check the Token Address: Ensure that the address you're using for the USDT token is correct. Any mistakes here could lead to further errors. Node Synchronization: Make sure the node you are querying is fully synced, so you are getting the most accurate data. Conclusion Retrieving your USDT balance can be a seamless process once you understand the structure of your code and the importance of the ABI. By following the steps outlined in this guide, you should be able to fetch your token balances effectively. Remember to check your configurations and address details if issues arise, and happy coding on your Ethereum journey!
