Ethereum: USDC Not Working Properly with Web3JS on Binance Smart Chain
As a growing ecosystem of decentralized applications (dApps) and smart contracts, Ethereum has become the platform of choice for many users. However, when it comes to interacting with certain assets such as stablecoins like USDC, things don’t always work as expected.
Recently, we noticed that using Web3JS on Binance Smart Chain with USDC transactions doesn’t seem to work properly. This issue affects both Ethereum and Polygon-based dApps that have successfully interacted with USDT, DAI, and SLP assets.
The problem:
When attempting to retrieve transaction receipts for USDC on Binance Smart Chain using Web3JS, the following error occurs:
Error: Invalid request: "
The "Invalid request" message suggests that the API is not configured correctly or that there is an issue with the asset ID. However, in our testing, we found that this error occurs even when using valid asset IDs.
Troubleshooting Steps:
To resolve this issue, try the following troubleshooting steps:
- Check your Binance Smart Chain settings:
Make sure you are connecting to the correct chain (e.g. BSC) and network (e.g. mainnet).
- Check your Web3JS library: Make sure you are using a compatible Web3JS library for Binance Smart Chain, e.g.bsc-dataseed1`.
- Check your asset IDs: Make sure you have entered the correct asset ID for USDC on BSC (0x…).
- Update your API request URL: Double check the API request URL to make sure it is correct.
Sample Code:
To get you started, here is a sample code snippet showing how to retrieve transaction receipts using Web3JS:
const Web3 = require('web3');
const bscedataseed1 = new Web3(new Web3.providers.HttpProvider('
const USDCAddress = '0x...'; // Replace with your USDC contract address on BSC
const assetId = 0x...; // Replace with the correct asset ID for USDC
const transactionReceipt = await bscedataseed1.getTransactionReceipt(
'0x...',
{ gas: 100000, from: '0x...', to: '0x...' }
);
// Process the transaction receipt
Conclusion:
While we have not identified a single cause for this issue, it is important to note that Web3JS is a complex library with many variables. If you are experiencing similar issues with Ethereum or Polygon-based dApps, please consult our community forums or support sections for further assistance.
If you encountered this error while using Binance Smart Chain and Web3JS, for now, try the troubleshooting steps above and update your code to display the correct asset IDs and API request URL. If the problem persists, please provide us with further details so that we can resolve it.
