Ethereum: bsctestnet contract cannot be confirmed

I see that you are facing issues with contract verification on the BSC (Binance Smart Chain) testnet using Remix.

Here is an article that addresses your concerns:

Ethereum: Contract on BSC testnet cannot be verified

When deploying tokens to 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 with contract verification on the BSC testnet using Remix.

In this article, we will 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 may not be visible or cannot be verified on the BSC testnet. Let’s look at some potential causes:

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

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

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

• Gas limit

  

  : The gas limit set on the BSC testnet is different than the one you deployed it to. Make sure 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.

• Verify contract address: Make sure the contract address you are 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 are still having issues after checking these steps, consider the following:

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

• Test on local network: Deploy your contract to 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 successfully verify your contract on the BSC testnet using Remix. If you are still having issues, feel free to share more details about your deployment and configuration, and I will do my best to help you resolve the issue.

Sample Use Cases

Here is a sample code snippet that demonstrates how to deploy a simple contract to 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.

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