There seems to be something wrong with the etherscan verification. The logs show that everything is already verified successfully but on Etherscan the contracts are not verified.

I manually verified a RollupCreator contract I deployed by running npx hardhat verify --network sepolia 0xc4F30D50A7Fdf79Bd54D35261511f204770E6cba and after that it ended up being verified on etherscan.

Do you by any chance have an idea why the verification from the deployment script looks like it's working but isn't.

Overall looks great. Left some comments. If it's not straight-forward to fix the etherscan verification we can open a separate issue for it and manually run hardhat verify if necessary.

Seems like they use a deprecated package to verify which might be causing the issue
