Ethereum: USDC does not work properly with web3Js on Binance Smart Chain
As a growing ecosystem of decentralized applications (DAPP) and intelligent contracts, Ethereum has become a platform for many users. However, when it comes to interaction with certain assets such as Stablacoins such as USDC, things do not always work as expected.
We have recently noticed that the use of web3Js in Binance Smart Chain seems to work properly with USDC transactions. This problem is influenced by Ethereum DAPP and polygon, which successfully interacted with USDT, DAI, SLP assets.
problem:
When attempting to retrieve the USDC transactions in Binance Smart Chain using web3Js, the following error occurs:
Error: Invalid Request:" ""
The 'Invalid application' report indicates that the API is not properly configured or that there is a problem with the property ID. In our testing, however, we have found that this error also occurs when the valid ID of assets.
Steps to solve problems:
To solve this problem, try the next steps of troubleshooting:
- Check your Binance smart chain settings: Be sure to connect to the correct string (eg BSC) and network (eg Mainnet).
- Check your Web3JS:
Library: You are using a compatible Web3JS library for the Binance smart chain, such as "BSC-Dataseed1".
- Check your ID assets: Make sure you have entered the correct asset ID for USDC on BSC (0x ...).
- Update the API request URL: Double Check the API URL to make sure it is correct.
Code Example:
To help you start, here is an example of a scrap of code that demonstrates how to load transactions receipts using web3Js:
Javascript
Const Web3 = Require (‘Web3’);
Const BSCEDATASEED1 = New Web3 (New Web3.Providers.httpprovider (‘
Const USDCADDRESS = ‘0x …’; // Replace your USDC contract address to BSC
Const Assetid = 0x …; // replace the correct asset ID for USDC
Const Transactionreceipt = Awaiting BSCEDATASEED1.GETTRANSACTIONRECEPT (
‘0x …’,
{Gas: 100000, from: ‘0x …’, to: ‘0x …’}
);
// process a transaction confirmation
`
Conclusion:
Although we have not found a single reason for this problem, it is necessary to note that web3Js is a comprehensive library with many variables. If you have similar problems on Ethereum or Polygon DAPP, please contact our community forums or support the sections where you will find further assistance.
Meanwhile, if you have encountered this error using Binance Smart Chain and Web3Js, try the above -mentioned problems of troubleshooting and update your code to reflect the correct asset ID and URL of the API request. If the problem persists, do not hesitate to provide more details to help it solve it.
