Ethereum: USDC is Not Working Properly with Web3JS on Binance Smart Chain
As a growing ecosystem of decentralized applications (dApps) and smart contracts, Ethereum has become the go-to platform for many users. However, when it comes to interacting with certain assets, such as stablecoins like USDC, things don’t always work out as expected.
Recently, we’ve noticed that using Web3JS on Binance Smart Chain doesn’t seem to be working properly with USDC transactions. This issue affects both Ethereum and Polygon-based dApps, which have successfully interacted with USDT, DAI, SLP assets.
The Problem:
When trying to fetch transaction receipts for USDC on Binance Smart Chain using Web3JS, the following error occurs:
Error: Invalid request: "
TheInvalid requestmessage suggests that the API is not properly configured or that there's an issue with the asset ID. However, in our testing, we've 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: Ensure you're connecting to the correct chain (e.g., BSC) and network (e.g., Mainnet).
- Verify your Web3JS library: Make sure you're using a compatible Web3JS library for Binance Smart Chain, such asbsc-dataseed1`.
- Check your asset IDs: Ensure that you’ve entered the correct asset ID for USDC on BSC (0x…).
- Update your API request URL: Double-check the API request URL to ensure it’s correct.
Example Code:
To help you get started, here’s an example code snippet demonstrating how to fetch transaction receipts with 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 haven’t identified a single cause for this issue, it’s essential to note that Web3JS is a complex library with many variables. If you’re experiencing similar issues on Ethereum or Polygon-based dApps, please consult our community forums or support sections for further assistance.
For now, if you’ve encountered this error using Binance Smart Chain and Web3JS, try the troubleshooting steps above and update your code to reflect the correct asset IDs and API request URL. If the issue persists, feel free to provide more details so we can help resolve it.
