I see that you are having issues verifying contracts on the BSC (Binance Smart Chain) testnet using Remix.
Here is an article that addresses your concerns:
Ethereum: Contract in bsctestnet cannot be verified
When deploying tokens on any blockchain network, including the BSC testnet, it is essential to ensure that your contract can be successfully verified and executed. However, we have encountered issues verifying contracts 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. is correct and matches the one used in Remix. You can use the
remix runcommand with the-vflag to verify the contract code.
- Incorrect Address: Verify that you are using the correct contract address for your implementation. Make sure it is correct 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 may not be recognized.
- Gas Limit: The gas limit set on the BSC test network is different from the one you deployed it to. Make sure that the function call limits of your contract 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-codeto verify your bytecode.--abi
- Verify contract address: Make sure the contract address you are using for your 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-codeto verify your ABI.--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 settings.
- Test on local network: Deploy the contract on a local BSC test node before deploying it to a live network.
- Use a code sniffer
: Use a code sniffer like
remix --code-scanto 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.
Example Use Case
Here is an example code snippet that demonstrates how to implement 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 implement this contract and verify it using the steps mentioned above.
I hope this helps! Let me know if you have any further questions or concerns.
