When I try to verify and publish my ERC721 contract code in etherscan gives this error. How do I correct it? Thank you. [Error etherscan] :computer: Environment :memo:Details :1234: Code to reproduce

Hi @ninoarteiro , Sorry for the delay, it took me a couple of attempts to verify your contract. I verified your contract: [image] Contract Address 0x3f513c0a9da9a3698219fb337208055c93b227c4 | Etherscan The Contract Address 0x3f513c0a9da9a3698219fb337208055c93b227c4 page allows users to …

Hi @ninoarteiro , Your contract is using GitHub imports. The current best way I know how to verify is as follows but you will need to convert imports to be from the package: Verify smart contract inheriting from OpenZeppelin Contracts If you get stuck, I can help you verify.

Hi @ninoarteiro , Checking that you were able to verify your token?

Thank you for your help. I still haven’t been able to verify. I tried to use the truffle flattener, but I couldn’t. Now I installed the plugin you recommended, but I can’t configure it. Can you guide me?

Hi @ninoarteiro , Can you share your Solidity smart contract code, any parameters passed to the constructor and if optimization was enabled. I can then verify and share my setup.

Optimization enabled. Code > https://drive.google.com/file/d/1PXMx-3nJgmzPkLrZsu2nEA78DCr66IbD/view?usp=sharing

Hi @ninoarteiro , Can you post the address and the unflattened contract smart contract and the constructor parameters?

The unflattened contract is on the link above. I don’t know what the constructor’s parameters are. Contract address, on the rinkeby network: 0x3f513c0a9da9a3698219fb337208055c93b227c4

I think I’m going to pay a programmer to finish this part for me. I paid a programmer to make the code for me. But the programmer is no longer available. I thought it would be easy to finish this rest. All that remained was to place the contract with access only for the owner and verify it on ethers…

To finish, I just need to flatten the code to verify in etherscan. I tried to use the truffle, but I couldn’t. Could you suggest me some programmer that I can pay to finish for me?

Andrew, thank you very much for your help. I tested it and it worked perfectly. The Openzeppelin team is doing an excellent job. The team is very efficient. Congratulations! :100:
