Hi @critesjosh. That error originates from the Etherscan API and there's not much we can do in our side. As a workaround, you may need to condense your source code or split it into several contracts. Closing for now, but if you have any more questions or need further assistance, feel free to reopen it or start a new one.

Huh. Seems silly that etherscan would have a limit on contract size that is below the on chain limit

schaable commented 8 months ago

Hey @critesjosh, sounds weird, yes. I'm happy to take a look if you can provide a minimal reproducible example

critesjosh commented 8 months ago

I actually refactored my contracts and it's working now. Thanks for the offer though 🙏
