Ethereum: Contract in bsctestnet cannot be verified

I see you are having trouble verifying your contract on the BSC (Binance Smart Chain) testnet using Remix.

Here is an article that addresses your concerns:

Ethereum: Contracts cannot be verified

When deploying a token on any blockchain network, including the BSC testnet, it is essential to ensure that your contract can be verified and executed successfully. However, I have encountered issues verifying my contract on the BSC testnet using Remix.

In this article, we will explore some possible reasons why your contract is rejected or cannot be verified on the BSC testnet.

Possible reasons for contract verification issues

There are several reasons why your contract may not be visible or cannot be verified on the BSC testnet. Let’s examine a few potential causes:

• Invalid bytecode

  : Make sure your contract bytecode is correct and matches the one used in Remix. You can use the remix run command with the -v flag to verify the contract code.

• Incorrect Address: Check that you are using the correct contract address for your implementation. Make sure that it is correct and that the ABI (Application Binary Interface) matches the contract.

• Incorrect ABI: Double-check that your contract ABI matches the one provided by Remix or another source. If the ABIs differ, the contract may not be recognized.

• Gas Limit: The gas limit set on the BSC testnet is different from what you set it for. Check that the function call limits of your contract match the required values.

Troubleshooting Steps

To resolve these issues and validate your contract on the BSC testnet, follow these steps:

• Verify bytecode with remix: Run remix run --network bsc --port 8545 --min-api-fee 10 --gas 1000000 --contract-code --abi to verify your bytecode.

• Check Contract Address: Make sure the contract address you are using to deploy is correct and matches the one listed in Remix or another source.

• Verify ABI with Remix: Run remix run --network bsc --port 8545 --min-api-fee 10 --gas 1000000 --contract-code --abi to verify your ABI.

Additional Tips

If you are still having issues after checking these steps, consider the following:

• Check Remix documentation: Make sure you are using Remix with the correct network and settings.

• Test on local network: Deploy your contract on a local BSC testnet node before deploying it to the live network.

• Use a code sniffer: Use a code sniffer such as remix --code-scan to scan your contract for errors.

By following these troubleshooting steps, you should be able to successfully validate your contract on the BSC testnet using Remix. If you are still having issues, feel free to share more details about your implementation and configuration, and I will do my best to help you resolve the issue.

Usage Example

Here is an example code snippet showing how to deploy a simple contract on the BSC testnet:

pragma solidity ^0.8.0;
contract My contract {

    uint256 public x;


    function setX ( uint256 _x ) public { { function setX ( uint256 _x ) public {

        x = _x;

    }}

}}

You can then use Remix to implement this contract and verify it according to the steps above.

Hope this helps! Let me know if you have any additional questions or concerns.
