Hey, @AskAlexSharov , as I see you've assigned a High priority here,just wanted to follow up and ask if you've been able to identify the culprit here?

[pgtodoroff]

Hey @AskAlexSharov , wanted to kindly bump this again. Would really appreciate some insights here when possible! 🙏

[AskAlexSharov]

@AskAlexSharov any update on this?

Hi, non-canonical block hashes with requireCanonical: false is not supported for eth_getStorageAt, eth_getCode, eth_getBalance, etc. in Erigon. Only canonical hashes would work.

Supporting requireCanonical: false would possibly be a big work item for us that at moment sits low on our priorities list. We do not expect to be able to work on it in the near future.

However, @deepakbnsl @pgtodoroff @danalchemy it would be good for us to understand your use case so we can plan for a good solution when the time comes. In what situations do you need to use this and why? Is it by any chance related to this https://github.com/erigontech/erigon/issues/1613 and hardhat forking from mainnet? Or is it something else?
