Ethereum: Contract in bsctestnet cannot be verified
I see you’re having trouble verifying contracts on the BSC (Binance Smart Chain) testnet using Remix.
Here’s an article that addresses your concerns:
Ethereum: Unable to verify contract in bsctestnet
When deploying tokens on any blockchain network, including the BSC testnet, it’s important to make sure your contract can be verified and run successfully. However, we’ve encountered issues verifying contracts on the BSC testnet using Remix.
In this article, we’ll explore some possible reasons why your contract is rejected or fails to be verified on the BSC testnet.
Possible Reasons for Contract Verification Issues
There are several reasons why your contract may not be visible or fails to be verified on the BSC testnet. Let’s look at some possible causes:
- Incorrect 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 check the contract code.
- Wrong address: Make sure you are using the correct contract address for your deployment. Make sure it is correct and matches the ABI (Application Binary Interface) contract.
- Wrong ABI: Double check that your contract ABI matches the one provided by Remix or any other source. If the ABIs are different, the contract may not be recognized.
- Gas limit: The gas limit set on the BSC testnet is different from what you deployed it for. 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 verifying these steps, consider the following:
- Check Remix’s documentation: Make sure you are using Remix with the correct network and settings.
- 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.
If you follow these troubleshooting steps, you should be able to successfully verify your contract on the BSC testnet using Remix. If you’re still having issues, feel free to share more details about your deployment and configuration with me and I’ll do my best to help you resolve the issue.
Example Use Case
Here’s a sample code snippet showing how to deploy a simple contract on the BSC testnet:
“solidity
pragma solidity ^0.8.0;
contract MyContract {
uint256 public x;
function setX(uint256 _x) public {
x = _x;
}
}
“
You can then deploy this contract using Remix and verify it using the steps above.
Hope this helps! Let me know if you have any other questions or concerns.
