I see you’re facing issues with verifying contracts on the BSC (Binance Smart Chain) testnet using Remix.

Here’s an article that addresses your concerns:

Ethereum: Contract in bsctestnet cannot be verified

When deploying tokens to any blockchain network, including the BSC testnet, it’s essential to ensure that your contract can be verified and executed successfully. However, I’ve encountered issues with verifying contracts on the BSC testnet using Remix.

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

Possible Reasons for Contract Verification Issues

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

• Incorrect Bytecode: Ensure that 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: Verify that you’re using the correct contract address for your deployment. Make sure it’s accurate and matches the contract ABI (Application Binary Interface).

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

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

Troubleshooting Steps

To resolve these issues and verify 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: Ensure that the contract address you’re using for deployment is correct and matches the one provided 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’re still encountering issues after verifying these steps, consider the following:

• Check Remix’s Documentation: Ensure that you’re 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 a live network.

• Use a Code Sniffer: Use a code sniffer like remix --code-scan to scan your contract for errors.

By following these troubleshooting steps, you should be able to verify your contract on the BSC testnet successfully using Remix. If you’re still experiencing issues, feel free to share more details about your deployment and configuration, and I’ll do my best to help you resolve the problem.

Example Use Case

Here’s an example code snippet that demonstrates how to deploy a simple contract on the BSC testnet:

pragma solidity ^0.8.0;


contract MyContract {

    uint256 public x;


    function setX(uint256 _x) public {

        x = _x;

    }

}

You can then use Remix to deploy this contract and verify it using the steps outlined above.

I hope this helps! Let me know if you have any further questions or concerns.
