Could anyone help me make sense of this error. For context. I had 2 contracts 1 will verify and the other won't. I noticed this when trying to merge them into 1 contract. The contract that is not verifying is an ERC1155.
I read on brownie gitter page that flattening the oz files aparently solves this. My questions are How do you work with the file after it's flattend? Are all my imports going to be local paths now? I havnt seen this before so Im assuming there is another way.. I tried using the flattend files to verify manually on etherscan but it doesnt work.. Do i need to install hardhat or truffle just to verify?? If anyone could explain this better though would be apreciated. Like why the contracts deployed and verified seperately but when combining them into one it fails verification..
