Hello! I'm trying to verify this contract on etherscan and ran into this error. I also tried out flattening the contract with the flatterer plugin in remix but that didn't work either. I would appreciate any help to solve, thank you!
Hi, welcome! 
If you deployed your contract with Remix, maybe you can have a look at this tutorial: Verify erc20 token on etherscan that was deployed through remix:step by step guide
And if you want to verify contracts by multi-files, I think you can look at this tutorial: Verify smart contract inheriting from OpenZeppelin Contracts
Hi Skyge, Thanks for the reply! I followed your first tutorial and this is what I got. Not really sure where to go from here.
It looks like just some warnings.
So could you please share the source code and contract address?
Sure!
